Software engineer and Checkstyle contributor who merged 100+ pull requests and built five new Google Java Style checks.

At Google Summer of Code 2026, I contributed to Checkstyle, merging 100+ pull requests and resolving 25+ issues in its Google Java Style configuration. I built and activated five new checks and reworked OneStatementPerLine.

I shipped those changes under 100% line-coverage and PIT mutation-testing gates, and updated the coverage page to the April 2026 style guide. In Social Winter of Code 2026, I built the plumbing layer of kitcat, a Git-like VCS in Go, and reviewed 14 pull requests.

In my projects, I built CrewSync, a real-time collaborative editor with an RGA CRDT, and Airhealth, an air-quality map and threshold-alert app. I also built apiCheck, a concurrent Go CLI for API health checks.
