100 Q&A Python with System Admin & Azure DevOps

 This post provides a comprehensive set of questions and answers designed to evaluate a candidate's proficiency across Python development, system administration, and Azure DevOps practices. The questions are divided into relevant categories to assess the full spectrum of skills required for this hybrid role.

Category 1: Core Python Programming (30 Questions)

1. What is the difference between a list and a tuple in Python? Answer: A list is mutable, meaning its elements can be changed, while a tuple is immutable, meaning its elements cannot be changed after creation. Tuples are generally faster and used for data that should not be modified, like coordinates or configuration settings.

2. What are Python decorators and provide a simple use case? Answer: A decorator is a function that takes another function as an argument, adds some functionality to it, and returns the modified function without altering the original function's code. A common use case is creating a timer decorator to measure the execution time of a function.

3. Explain the Global Interpreter Lock (GIL) in CPython. Answer: The GIL is a mutex that protects access to Python objects, preventing multiple native threads from executing Python bytecodes at the same time. This means that even on a multi-core processor, only one thread can execute Python code at once, which can be a performance bottleneck for CPU-bound, multi-threaded programs.

4. What is the difference between __init__ and __new__? Answer: __new__ is the first step in instance creation; it's responsible for creating and returning a new, empty object. __init__ is the initializer; it takes the newly created object and initializes its attributes. You would use __new__ when you need to control the creation of a new instance, like subclassing an immutable type.

5. What are list comprehensions and why are they useful? Answer: List comprehensions provide a concise way to create lists. They are often more readable and faster than using a for loop to build a list. For example, squares = [x*x for x in range(10)].

6. What is a Python generator? How is it different from a normal function? Answer: A generator is a function that returns an iterator using the yield keyword. Unlike a normal function that computes all values at once and returns them, a generator yields one value at a time, pausing its state between calls. This is highly memory-efficient for working with large data streams.

7. What are *args and **kwargs? Answer: They are used to pass a variable number of arguments to a function. *args is used to pass a non-keyworded, variable-length argument list (as a tuple). **kwargs is used to pass a keyworded, variable-length argument list (as a dictionary).

8. Explain how exception handling works in Python. Answer: It works using try, except, else, and finally blocks. The try block contains code that might raise an exception. The except block catches and handles the specific exception. The else block executes if no exception occurs. The finally block executes regardless of whether an exception occurred, and is typically used for cleanup actions.

9. What is the difference between a shallow copy and a deep copy? Answer: A shallow copy creates a new object but inserts references to the objects found in the original. A deep copy creates a new object and recursively copies all objects found in the original, creating fully independent copies.

10. What is duck typing? Answer: Duck typing is a concept where the type or class of an object is less important than the methods it defines. "If it walks like a duck and it quacks like a duck, then it must be a duck." In Python, this means you can use any object that provides the required methods, without forcing it to be a subclass of a particular type.

11. How do you manage package dependencies in a Python project? Answer: By using a requirements.txt file, which lists all project dependencies. This file is typically used with a virtual environment (venv) to isolate project dependencies from the system-wide Python installation. Tools like pip freeze > requirements.txt are used to generate the list.

12. What is the purpose of the if __name__ == "__main__": block? Answer: This block of code will only execute when the Python script is run directly, not when it is imported as a module into another script. It's used to contain code that should only be run at the top level, like tests or a command-line interface.

13. What are f-strings and why are they preferred? Answer: F-strings (formatted string literals) provide a way to embed expressions inside string literals, using curly braces {}. They are preferred because they are more readable, more concise, and faster than other string formatting methods like %-formatting or str.format().

14. What is the difference between .py and .pyc files? Answer: .py files contain the human-readable source code. .pyc files contain the compiled bytecode of the Python code. Python compiles source code into bytecode to improve performance on subsequent executions.

15. What is a context manager and what is the with statement used for? Answer: A context manager is an object that defines the methods __enter__ and __exit__. The with statement is used to wrap the execution of a block of code with methods defined by the context manager, typically for resource management like opening/closing files or database connections, ensuring cleanup happens automatically.

16. What is method overriding in Python? Answer: Method overriding is an object-oriented programming feature that allows a subclass to provide a specific implementation of a method that is already provided by one of its parent classes.

17. How does Python's garbage collection work? Answer: CPython's primary garbage collection mechanism is reference counting. Every object has a count of the number of references pointing to it. When the count drops to zero, the object's memory is deallocated. It also has a cyclic garbage collector to detect and clean up reference cycles.

18. What is Pip and what is its purpose? Answer: Pip is the standard package manager for Python. It allows you to install and manage third-party libraries and dependencies from the Python Package Index (PyPI).

19. What is the difference between is and ==? Answer: is checks if two variables point to the same object in memory (identity). == checks if the values of two variables are equal (equality).

20. What are Python's built-in data types? Answer: The main built-in types are numeric (int, float, complex), sequence (list, tuple, range), text (str), mapping (dict), set types (set, frozenset), and boolean (bool).

21. How would you read a large file line-by-line in Python? Answer: The most memory-efficient way is to use a with statement and iterate directly over the file object: with open('large_file.txt', 'r') as f: for line in f: process(line). This reads the file line by line without loading the entire file into memory.

22. What is a lambda function? Answer: A lambda function is a small, anonymous function defined with the lambda keyword. It can take any number of arguments but can only have one expression. It's often used for short, simple operations, for example as an argument to sorted() or map().

23. What is the requests library used for? Answer: The requests library is used for making HTTP requests to web services and APIs. It simplifies the process of sending GET, POST, PUT, DELETE requests and handling their responses.

24. How can you make an HTTP POST request with JSON data using requests? Answer: import requests; requests.post('https://api.example.com/data', json={'key': 'value'})

25. What is the purpose of a virtual environment? Answer: A virtual environment creates an isolated space for a Python project, with its own interpreter and installed packages. This allows you to manage dependencies for different projects separately and avoid conflicts between package versions.

26. What is serialization in Python? Give an example of a library used for it. Answer: Serialization is the process of converting a Python object into a format that can be stored (e.g., in a file) or transmitted (e.g., over a network). The pickle library is used for serializing Python objects into a binary format, and the json library is used for serializing them into the standard JSON format.

27. What is a dictionary comprehension? Answer: Similar to a list comprehension, a dictionary comprehension provides a concise way to create dictionaries. For example: squares_dict = {x: x*x for x in range(5)}.

28. How would you handle a KeyError when accessing a dictionary? Answer: You can use the .get() method, which returns None (or a specified default value) if the key is not found, instead of raising a KeyError. Alternatively, you can use a try...except KeyError block.

29. What is the difference between a module and a package in Python? Answer: A module is a single Python file (.py). A package is a way of organizing related modules into a directory hierarchy. A directory becomes a package if it contains a special file named __init__.py.

30. What does the pass statement do? Answer: The pass statement is a null operation; nothing happens when it executes. It is used as a placeholder in code where a statement is syntactically required, but no action needs to be taken, such as in an empty function or class definition.

Category 2: System Administration & Networking (25 Questions)

31. How would you check the CPU and memory usage of a specific process on Linux? Answer: You can use the top or htop command and find the process in the list. Alternatively, for a specific process ID (PID), you can use ps -p <PID> -o %cpu,%mem.

32. What is the purpose of systemd in modern Linux distributions? Answer: systemd is an init system and service manager. Its primary purpose is to initialize the system and manage system services (daemons) after the kernel has booted, including starting, stopping, and restarting services.

33. Explain the difference between a hard link and a symbolic (soft) link. Answer: A hard link is a direct reference to a file's inode; it's like a second name for the same file. A symbolic link is a separate file that contains a path to the target file; it's like a shortcut. Deleting the original file breaks a symbolic link but does not affect a hard link until all hard links to the inode are removed.

34. How would you find all files larger than 1GB in the current directory and its subdirectories? Answer: Using the find command: find . -type f -size +1G

35. What is an SSH key and how does it provide more secure authentication than a password? Answer: An SSH key pair consists of a public key (which is placed on the server) and a private key (which is kept secret on the client). Authentication works by the client proving it possesses the private key that corresponds to the public key. This is far more secure than a password because the private key is much more complex and is never transmitted over the network.

36. What is the purpose of a firewall? What is iptables? Answer: A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. iptables is a command-line utility in Linux used to configure the kernel's firewall ruleset (netfilter).

37. Explain what a DNS A record and CNAME record are. Answer: An A record (Address record) maps a domain name directly to an IPv4 address. A CNAME record (Canonical Name record) maps a domain name to another domain name (an alias).

38. How would you check which ports are open and listening on a Linux server? Answer: Using the netstat or ss command: netstat -tuln or ss -tuln.

39. What is the difference between TCP and UDP? Answer: TCP (Transmission Control Protocol) is a connection-oriented protocol that provides reliable, ordered, and error-checked delivery of a stream of bytes. UDP (User Datagram Protocol) is a connectionless protocol that is faster but does not provide any guarantee of delivery, order, or error checking.

40. What is RAID and what are RAID 0, 1, and 5? Answer: RAID (Redundant Array of Independent Disks) is a technology for combining multiple physical disk drives into a single logical unit.

    • RAID 0 (Striping): Offers performance but no redundancy.

    • RAID 1 (Mirroring): Offers redundancy by writing the same data to two disks.

    • RAID 5 (Striping with Parity): Offers a balance of performance and redundancy, using parity information to rebuild data if one disk fails.

41. How would you write a bash script to back up a directory? Answer: A simple script would use tar:

    #!/bin/bash
    TIMESTAMP=$(date +"%F")
    tar -czvf /backups/my-backup-$TIMESTAMP.tar.gz /path/to/directory
    
    

42. What is the /etc/fstab file used for? Answer: The /etc/fstab (file systems table) file is used to define how disk partitions and other block devices should be mounted into the filesystem at boot time.

43. What is a subnet mask and why is it needed? Answer: A subnet mask is used to divide an IP address into two parts: the network address and the host address. It allows devices to determine if another IP address is on the same local network or on a remote network.

44. How do you view and follow log files in real-time on Linux? Answer: Using the tail command with the -f (follow) flag: tail -f /var/log/syslog.

45. What is the purpose of cron? How would you schedule a script to run every day at 3 AM? Answer: cron is a time-based job scheduler in Unix-like operating systems. To schedule a script, you would edit the crontab (crontab -e) and add the line: 0 3 * * * /path/to/your/script.sh.

46. What is PowerShell and how does it differ from CMD on Windows? Answer: PowerShell is a modern, powerful command-line shell and scripting language built on the .NET Framework. It is object-oriented, allowing you to pipe objects between commands (cmdlets), whereas CMD is a traditional shell that pipes simple text strings.

47. How do you check the routing table on a Windows server? Answer: Using the route print or Get-NetRoute command in PowerShell.

48. What is Active Directory? Answer: Active Directory (AD) is Microsoft's directory service for Windows domain networks. It is used for centralized domain management, authentication, and authorization.

49. What is the function of a load balancer? Answer: A load balancer distributes incoming network traffic across multiple backend servers to ensure no single server becomes overwhelmed. This improves application availability, reliability, and performance.

50. What is I/O redirection in Linux? Give an example. Answer: I/O redirection allows you to change where a command's standard input, standard output, and standard error go. For example, ls -l > file_list.txt redirects the standard output of ls -l to a file named file_list.txt.

51. What is the chmod command used for? What does chmod 755 mean? Answer: The chmod command is used to change the permissions of files and directories. chmod 755 sets the permissions to rwxr-xr-x: the owner has read, write, and execute permissions (7); the group has read and execute permissions (5); and others have read and execute permissions (5).

52. How would you troubleshoot a slow network connection between two servers? Answer: I would start by using ping to check latency and packet loss. Then, I would use traceroute (or tracert on Windows) to identify potential bottlenecks along the network path. I would also check for network interface errors using ifconfig or ip a.

53. What is an Inode in a Linux filesystem? Answer: An inode is a data structure that stores all the information about a file—such as its size, permissions, owner, and location on the disk—except for its name and the actual data content.

54. What is the purpose of the sudo command? Answer: The sudo (superuser do) command allows a permitted user to execute a command as the superuser or another user, as specified by the security policy in the /etc/sudoers file.

55. What is a "shebang" (#!) at the beginning of a script? Answer: A shebang tells the operating system which interpreter to use to execute the script. For example, #!/usr/bin/python3 specifies that the script should be run with the Python 3 interpreter.

Category 3: Azure DevOps (30 Questions)

56. What is Azure DevOps? What are its main components? Answer: Azure DevOps is a suite of services that provides an end-to-end solution for planning, developing, testing, and delivering software. Its main components are Azure Boards (work tracking), Azure Repos (Git hosting), Azure Pipelines (CI/CD), Azure Test Plans (testing), and Azure Artifacts (package management).

57. Explain the difference between a build pipeline and a release pipeline in Azure Pipelines. Answer: A build pipeline (now often just called a "pipeline" in multi-stage YAML) is responsible for Continuous Integration (CI). It takes source code, compiles it, runs tests, and produces a deployable package called an artifact. A release pipeline is responsible for Continuous Deployment (CD). It takes the artifact from the build pipeline and deploys it to various environments like Dev, QA, and Production.

58. What is a "stage" in a YAML pipeline? Answer: A stage is a major logical boundary in a pipeline, representing a collection of jobs. Common stages include "Build," "DeployDev," and "DeployProd." Each stage runs independently and can have its own conditions and approvals.

59. What is an Azure DevOps Agent? What are Microsoft-hosted vs. self-hosted agents? Answer: An agent is a piece of software that runs on a machine to execute jobs in a pipeline. Microsoft-hosted agents are managed by Microsoft and provide a fresh virtual machine for every job. Self-hosted agents are set up and managed by you on your own machines (on-prem or in the cloud), giving you more control over the environment and software.

60. What is Infrastructure as Code (IaC)? Name two IaC tools used with Azure. Answer: IaC is the practice of managing and provisioning infrastructure through machine-readable definition files (code), rather than through manual configuration. Two common tools for Azure are Azure Resource Manager (ARM) templates or Bicep, and the cloud-agnostic tool Terraform.

61. What is the purpose of an Azure Key Vault? How would you use it in a pipeline? Answer: Azure Key Vault is a service for securely storing and accessing secrets, keys, and certificates. In a pipeline, you would link the Key Vault to a variable group and reference secrets securely, so they are never exposed in logs or scripts.

62. What is a Dockerfile? Answer: A Dockerfile is a text file that contains a set of instructions for building a Docker image. It specifies the base image, commands to install software, files to copy, ports to expose, and the command to run when a container is started from the image.

63. Explain the purpose of Azure Container Registry (ACR). Answer: ACR is a private, managed Docker registry service in Azure. It is used to store and manage your private Docker container images, which can then be deployed to services like Azure Kubernetes Service (AKS) or Azure App Service.

64. What is Azure Kubernetes Service (AKS)? Answer: AKS is a managed container orchestration service in Azure that simplifies deploying, managing, and scaling containerized applications using Kubernetes. It offloads the operational overhead of managing the Kubernetes control plane to Azure.

65. How can you trigger an Azure Pipeline automatically? Answer: You can set up a CI trigger in the YAML file to automatically run the pipeline whenever a change is pushed to a specific branch (e.g., main) in your Git repository. You can also set up scheduled triggers or triggers based on the completion of another pipeline.

66. What is a variable group in Azure DevOps? Answer: A variable group is a collection of variables that can be shared across multiple pipelines. They are useful for storing values that you want to manage in one place, such as connection strings or secrets linked from an Azure Key Vault.

67. What is Azure App Service? Answer: Azure App Service is a fully managed platform for building, deploying, and scaling web apps and APIs. It supports multiple languages and frameworks (like Python, .NET, Node.js) and handles the underlying infrastructure for you.

68. What is a deployment slot in Azure App Service? Answer: A deployment slot is a live app with its own hostname. It allows you to deploy a new version of your app to a non-production slot (like "staging"), test it, and then swap it with the production slot with zero downtime.

69. What is Azure Functions? When would you use it? Answer: Azure Functions is a serverless compute service that allows you to run small pieces of code ("functions") in response to events, without having to manage any infrastructure. You would use it for event-driven tasks, like processing a file when it's uploaded to Blob Storage or running a scheduled cleanup job.

70. What is Azure Monitor? Answer: Azure Monitor is a comprehensive solution for collecting, analyzing, and acting on telemetry data from your Azure and on-premises environments. It helps you understand how your applications are performing and identify issues affecting them.

71. What is the difference between ARM templates and Bicep? Answer: ARM templates are JSON files used for declarative IaC in Azure. Bicep is a domain-specific language (DSL) that transpiles to ARM templates. Bicep was created to provide a much cleaner, more readable, and simpler syntax for writing IaC compared to the verbosity of JSON ARM templates.

72. What is the azure-pipelines.yml file? Answer: It is the YAML file that defines your CI/CD pipeline as code. It lives in your repository alongside your application code and specifies the stages, jobs, and steps of your pipeline.

73. How do you manage environments and approvals in Azure Pipelines? Answer: You define "Environments" in Azure DevOps, which can represent your Dev, QA, or Prod infrastructure. In your YAML pipeline, you can target a deployment job at a specific environment and configure approval checks, requiring one or more users to approve the deployment before it proceeds.

74. What is Azure Artifacts? Answer: Azure Artifacts is a service that allows you to create, host, and share package feeds (like NuGet, npm, Maven, and Python packages) within your organization. It allows you to manage dependencies in a secure, centralized location.

75. What is a service connection in Azure DevOps? Answer: A service connection provides a secure way for Azure Pipelines to connect to external and remote services, such as your Azure subscription, a container registry, or an on-premise server, without having to embed credentials directly in your pipeline.

76. What is the purpose of the "build agent pool"? Answer: A pool is a collection of agents. When a pipeline runs, it requests an agent from a specific pool. This allows you to group agents with specific capabilities (e.g., agents with macOS and Xcode, or self-hosted agents with special software).

77. How would you use Python to interact with Azure services? Answer: By using the Azure SDK for Python. There are libraries for nearly every Azure service (e.g., azure-storage-blob, azure-keyvault-secrets, azure-identity) that allow you to programmatically manage resources, upload data, and interact with services.

78. What is Azure Policy? Answer: Azure Policy is a service that helps you enforce organizational standards and assess compliance at scale. You can create policies that, for example, only allow resources to be deployed in specific regions or require certain tags on all resources.

79. What is a "task" in an Azure Pipeline? Answer: A task is the smallest building block of a pipeline. It is a pre-packaged script that performs an action, such as running a command-line script, building a .NET project, or deploying an ARM template.

80. How do you ensure code quality in your CI pipeline? Answer: By integrating several steps:

    • Linting: Using tools like Pylint or Flake8 to check for style issues.

    • Unit Testing: Running tests with a framework like Pytest and checking for code coverage.

    • Static Analysis: Using tools like SonarCloud to detect bugs, vulnerabilities, and code smells.

81. What is GitFlow? Answer: GitFlow is a branching model for Git that defines a strict branching structure around a project release. It provides a robust framework for managing larger projects with distinct main, develop, feature, release, and hotfix branches.

82. What is Azure CLI and why is it useful? Answer: The Azure CLI is a cross-platform command-line tool for managing Azure resources. It's useful for automation, allowing you to write scripts to create, update, and delete resources declaratively, which is essential for DevOps practices.

83. What is a multi-stage YAML pipeline? Answer: It's a single YAML file that defines both the CI (build) and CD (deployment) processes for an application. It provides a unified view of the entire lifecycle, from code commit to production deployment, as code.

84. What is Azure Blueprints? Answer: Azure Blueprints is a service that allows you to define a repeatable set of Azure resources, policies, and role assignments that can be deployed as a single package. It helps ensure that new environments are created in a consistent and compliant way.

85. How would you secure a web application running on Azure App Service? Answer: By implementing multiple layers of security: using managed identities to access other resources, storing secrets in Key Vault, configuring network restrictions, enabling authentication/authorization, and using a Web Application Firewall (WAF).

Category 4: Scenario-Based & Behavioral Questions (15 Questions)

86. A developer tells you "the build is broken." Describe the steps you would take to troubleshoot. Answer: First, I would check the Azure Pipelines build results for the specific error message and logs. I'd identify which task failed. I would then try to reproduce the error on my local machine. I'd check recent code commits to see what changed. Finally, I would communicate with the developer to get more context on their changes.

87. You need to deploy a Python web application to Azure. What service would you choose and why? Answer: For most standard web applications, I would choose Azure App Service. It is a fully managed platform that simplifies deployment and scaling. It has built-in support for Python, handles the underlying OS and web server, and offers features like deployment slots for zero-downtime deployments, making it very efficient.

88. You are tasked with writing a Python script to clean up old files from an Azure Blob Storage container. How would you approach this? Answer: I would use the Azure SDK for Python (azure-storage-blob). The script would authenticate using a managed identity or service principal, list all blobs in the container, iterate through them, check the last_modified property of each blob, and if it's older than a specified threshold (e.g., 90 days), I would call the delete_blob method. I would schedule this script to run periodically using an Azure Function with a timer trigger.

89. A production server is experiencing high CPU usage. How would you investigate the cause as a system admin? Answer: I would first SSH into the server and use top or htop to identify the specific process consuming the most CPU. I would then use tools like strace to see what system calls the process is making, or lsof to see what files it has open. I'd also check the application logs and system logs (/var/log/syslog) for any related error messages.

90. Describe a time you automated a manual process. What was the process and what was the impact? Answer: (The candidate should provide a specific example). A good answer would describe a manual reporting or deployment task, explain the Python script or pipeline they built to automate it, and quantify the impact in terms of time saved, errors reduced, or increased deployment frequency.

91. How do you stay up-to-date with the latest trends in Python, system administration, and Azure? Answer: I follow key industry blogs, subscribe to newsletters like Python Weekly and Azure Weekly, participate in online communities like Stack Overflow and Reddit, and dedicate time to hands-on learning with new features in my personal Azure account or through Microsoft Learn.

92. You need to provision a complex, multi-tier environment in Azure. Would you use the Portal, CLI, or an IaC tool? Why? Answer: I would use an IaC tool like Terraform or Bicep. While the Portal is good for exploration and the CLI is good for single commands, only an IaC tool can provision a complex environment in a reliable, repeatable, and documented way. It allows for version control of my infrastructure and easy teardown and recreation.

93. How do you handle secrets (like database passwords) in your Python application and your Azure DevOps pipelines? Answer: I follow a strict "no secrets in code" policy. Locally, I use environment variables or a .env file (which is in .gitignore). In Azure, all secrets are stored in Azure Key Vault. My application uses a Managed Identity to authenticate to Key Vault and retrieve the secrets at runtime. In the pipeline, I use a variable group linked to Key Vault to securely inject secrets into the deployment tasks.

94. What is your approach to code reviews? Answer: My approach is to be constructive and collaborative. I focus on the "what" and "why," not the "who." I look for correctness, readability, maintainability, and adherence to project standards. I always provide specific suggestions for improvement and am also open to discussing different approaches.

95. A deployment to the production environment failed late at night. What do you do? Answer: My immediate priority is to restore service. I would use the pipeline's rollback feature or swap back to the previous version using deployment slots to immediately revert the change. Once production is stable, I would begin a post-mortem analysis of the deployment logs to understand the root cause, but I would not attempt to push a new fix until it was fully understood and tested.

96. How would you design a CI/CD pipeline for a containerized Python application destined for AKS? Answer:

    1. CI Stage: Trigger on push to main. Lint and run unit tests. Build the Docker image using a Dockerfile. Push the versioned image to Azure Container Registry (ACR).

    2. Deploy to Dev Stage: Use the new image to deploy to the Dev namespace in AKS using a Kubernetes manifest file (or Helm chart). Run integration tests.

    3. Deploy to Prod Stage: After manual approval, trigger the deployment to the Prod namespace in AKS, updating the deployment with the new image tag.

97. Tell me about a challenging technical problem you solved. Answer: (The candidate should provide a specific, detailed story). A strong answer will clearly articulate the problem, the steps they took to investigate it, the solution they implemented, and what they learned from the experience. It should demonstrate their problem-solving and technical skills.

98. How do you balance speed of delivery with quality and security in a DevOps environment? Answer: By automating quality and security checks early in the pipeline (a "shift-left" approach). We don't see them as trade-offs, but as integrated parts of the process. By automating linting, unit tests, static code analysis, and security scanning in the CI phase, we ensure that every commit meets a certain quality bar before it can even be considered for deployment, allowing us to deliver quickly and safely.

99. Imagine you've written a Python script to process data, but it's too slow. What steps would you take to optimize it? Answer: First, I would use a profiler (like cProfile) to identify the exact bottlenecks in the code. Based on the results, I would look for algorithmic improvements, such as using more efficient data structures (e.g., a set for membership testing instead of a list). I would also check for inefficient I/O operations. If it's a CPU-bound problem, I might explore using multiprocessing.

100. Why do you think a role combining Python, SysAdmin, and Azure DevOps is a good fit for you? Answer: I thrive on seeing the big picture and owning the entire application lifecycle. My Python skills allow me to build the application and create automation scripts. My system administration background gives me the knowledge to manage the underlying infrastructure and troubleshoot issues. And my Azure DevOps experience allows me to tie everything together, building robust, automated pipelines that deliver value efficiently and reliably. I enjoy working across these different domains to build and maintain resilient systems.
