About this gig

Is your React or JavaScript site throwing errors and costing you time?


I'm a full-stack MERN developer who specialises in finding and fixing bugs fast with a full explanation of what went wrong and why, so it doesn't happen again.


WHAT I FIX:

TypeError, ReferenceError, undefined errors

React white screen / blank page issues

CORS errors and API call failures

useState, useEffect, and hook-related bugs

Next.js build errors and routing issues

npm / package dependency conflicts

Console errors and broken UI components

MongoDB connection and query errors


WHY CHOOSE ME:

Root-cause report included not just a patch

Free re-check within 7 days if the issue returns

Clean, commented code so you understand the fix

Clear communication throughout no ghosting


YOU WILL RECEIVE:

Fixed and tested source code

Written explanation of the bug and fix

Deployment-ready files if needed


Drop your error message, GitHub link, or a quick description of the problem I'll review it before you even place an order.
