About this gig

App broken? Error you can't figure out? I'll find it and fix it fast.


I'm a Full Stack Developer working daily with React, Next.js, Node.js and React Native, with real production systems in my portfolio (including work for Scania Brasdiesel).


WHAT YOU GET:


- Bug diagnosed and FIXED (not just patched)

- Clear explanation of what caused it so it doesn't come back

- Testing to confirm the fix didn't break anything else

- Clean code, following your project's patterns

- 24-48h delivery on most fixes


I FIX:


Crashes, errors, broken layouts, API issues, form problems, deployment errors, performance issues and "it works on my machine" mysteries.


HOW IT WORKS:


Send me the error (screenshot/message) and access to the code (GitHub or zip). I'll confirm the diagnosis before starting no surprises.


Message me with your error and I'll tell you right away if I can fix it and how fast.
