About this gig

Got a bug that's eating your time? I'll find it and fix it.


I debug and fix issues in JavaScript, TypeScript, React, and Node.js projects broken components, API errors, build failures, and behavior that "only happens sometimes."


How it works:

1) You send the repo or code and a short description of the bug.

2) I reproduce it, find the root cause, and fix it properly no quick patches.

3) You get the fix plus a short note on what was wrong and how I fixed it.


I don't just make the error disappear I make sure it stays gone. Clear communication, fast turnaround, and clean code you fully own.


Not sure if your bug fits a single order? Message me first with the details and I'll confirm the scope before you order.
