May 2025 — aws/aws-cdk-cli: Focused on aligning CLI UX with actual behavior and reducing user confusion. Delivered a targeted bug fix to the integ-runner CLI: corrected the --clean option help text to accurately describe its behavior of cleaning up and deleting stacks after test completion. This directly improves reliability of test workflows in CI and reduces support queries related to test cleanup behavior. Overall impact includes clearer developer guidance, more predictable automation, and better maintainability of the CLI help/docs. Technologies/skills demonstrated include TypeScript/Node.js CLI development, UX messaging accuracy, and rigorous commit hygiene with traceable fixes.
