About this gig

MERN app broken before a demo or deploy? I'll fix 1 bug in 24h $15, no-risk.


I debug React, Node.js, Express, MongoDB & Firebase fast without breaking what's working. You get the fix + a 1-line explanation of why it broke.


What I fix:

- React: white screen, state/routing, form/API fetch errors

- Node/Express: CORS, auth, crash loops, API 500s

- MongoDB: connection/query/schema issues

- Deployment: Vercel/Railway/Render env & build failures

- Stripe webhooks, Firebase auth tokens


How it works:

1. Send error + repo access

2. I find root cause

3. Patch, test, deliver clean diff with explanation


New Seller Advantage: $15 Quick Fix is my review magnet you get senior-level debugging at junior price. Fast replies (under 1hr) + 1-day delivery.


Complex or multiple bugs? Message me first I'll quote Standard/Premium honestly, no surprise charges.
