About this gig

Stuck on a bug that's eating your time? Site broken, app crashing, API failing? Send it my way.


I'm a full-stack developer who debugs and fixes issues in modern web projects, and I explain what went wrong so it doesn't happen again.


I CAN FIX:

React / Next.js errors (hydration issues, state bugs, routing, build failures)

Node.js / Express API errors and crashes

MongoDB connection and query problems

JavaScript / TypeScript errors

CSS and responsive layout problems

Deployment and build errors (Vercel and similar)

Auth, Socket.IO, and API integration problems


HOW IT WORKS:

1. Message me with the problem (screenshots or error messages help).

2. I confirm I can fix it and give a clear timeline.

3. I fix it, test it, and explain what caused it.


WHY ME?

- Fast turnaround

- Clean fixes, not messy workarounds

- Clear explanation of the cause

- I'll tell you honestly before ordering if I can't fix something


Message me before ordering, and I'll take a quick look for free.
