During February 2025, Caigen contributed to the App-vNext/Polly repository by refactoring the chaos injection configuration to improve resilience testing workflows. He focused on enhancing the clarity and maintainability of fault, latency, outcome, and behavior injection rates, renaming constants for greater specificity and updating example code in C#. Alongside these code changes, Caigen revised documentation to clarify the sequential nature of chaos injections and their effects on the resilience pipeline, supporting more accurate testing and easier onboarding for engineers. His work emphasized code readability, traceable commits, and comprehensive documentation, leveraging skills in C# and technical writing to empower future development.
