Got a bug you can describe but haven't had time to chase down? Send me the steps to reproduce it and access to the repo, and I'll find the root cause and fix it in your TypeScript/JavaScript (Next.js, React, Node.js) or Python codebase. Every fix comes with a test that fails before the change and passes after it, so the bug can't quietly come back. You get a pull request that passes your linter and test suite, plus a short plain-English note on what was wrong, why it happened and how the fix works. If the bug turns out to be bigger than one fix, I'll tell you before going further. I use AI coding tools and review, test and explain every change myself.
