I work on practical software maintenance:
- bug fixes with regression tests
- CI and build failure diagnosis
- Windows/Linux compatibility fixes
- CLI and developer-tooling issues
- focused code review with clear bug reports
Recent work includes merged open-source pull requests across TypeScript, JavaScript, Python, and developer tooling projects.
