During May 2025, Richard Choi contributed backend development and scripting expertise to the microsoft/VirtualClient repository, focusing on feature delivery and release management. He implemented elevated script execution by introducing a RunElevated parameter to the ScriptExecutor, enabling scripts to run with elevated privileges across PowerShell and Python executors. This enhancement improved automation consistency and security for cross-platform scenarios. Richard updated and expanded unit tests in C# to ensure robust validation of the new functionality. He also managed disciplined versioning by bumping the project to 2.0.14, supporting release hygiene. The work demonstrated depth in backend engineering and careful attention to deployment practices.
