Open Source Contributions

I contribute to infrastructure and networking projects I use in production. These contributions were made with the help of ◈ Claude Code — AI-assisted code review that helped me find real bugs: unchecked errors, nil panics, resource leaks, race conditions. I review every line, understand every fix, and test before submitting. Claude finds patterns I'd miss; I provide the domain context and production experience.
