Hi, I am Bin

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.

Available for Small Maintenance Projects

I take focused software maintenance work through Upwork:

How I Usually Work

1. Reproduce the issue.
2. Identify the root cause.
3. Make a focused patch.
4. Add or update tests.
5. Provide clear validation steps.

I prefer small, reviewable changes with clear scope and evidence.
