You will get debugging and errors fixed in your code within 24 hours
Project details
Stuck on an error in your React, Next.js, Node.js, or Express app that's blocking your launch or deadline? I'll find the root cause and fix it — fast.
This is a focused debugging service for developers, founders, and teams who need a specific error or bug resolved without hiring for a full project. I work across the MERN stack (MongoDB, Express, React, Node) plus Next.js and SQL databases, and I don't just patch the symptom — I identify why the error is happening so it doesn't resurface.
What I need from you:
The error message or a description of the bug
Access to the repo or relevant code
Any steps to reproduce the issue
What you get:
Root-cause diagnosis, not a quick patch
The fix applied directly, tested, and explained
A short note on what caused it (so you can avoid it next time)
I use AI-assisted debugging tools to scan and trace issues faster, but every fix is verified and tested by me before delivery — accuracy over speed-for-speed's-sake.
100% Job Success Score, 4.9★ across 90+ projects. If your issue turns out to be bigger than a single bug (missing feature, broken deployment, etc.), message me first and I'll scope it properly rather than starting blind.
