I will fix your nodejs and nextjs bugs crashes and errors fast
Hamza Nafasat
About this gig
Nodejs debugging and Nextjs debugging for crashes, broken APIs, and production errors. If your app works locally but fails deployed, I find the root cause and fix it fast.
I specialize in full stack debugging across Node.js and Next.js. Server crashes, broken API endpoints, memory leaks, database connection issues, environment variable problems, and build errors that only show up after deployment.
Most bug fixing jobs I get are ones the developer already tried to fix. The error is either vague, hard to reproduce locally, or shows up in production when everything worked in development. That is exactly the nodejs crash fix and nextjs crash fix work I do best.
What I fix:
Node.js and Next.js runtime crashes and errors
Broken API endpoints and server-side failures
Server-side rendering and hydration errors
Docker and deployment environment bugs
Database and auth issues
Build failures on Vercel, Railway, and VPS
I trace the root cause first, explain what broke and why, then fix it properly so the same problem does not come back.
Send me your error logs or describe what is happening and I will tell you if I can fix it before you order.

Founders hire me when they need a full stack developer who understands the whole system. Not just the code. The deployment, the auth, the database, the AI layer and how it all holds together under real usage.

FAQ
What information do you need to start fixing my bug?
Your error message or logs and a short description of what the app is doing versus what it should do. GitHub access is helpful but not always required to get started.
Can you fix bugs without access to my full codebase?
Yes in most cases. Share the relevant files or the section where the error is occurring and I can work from that. For complex issues full repo access speeds things up significantly.
What if you cannot find or fix the bug?
I only accept orders I am confident I can solve. If after reviewing your issue I think it is outside scope I will tell you before you pay anything.
Do you fix bugs in deployed apps or only local code?
Both. I regularly handle nodejs crash fix and nextjs crash fix issues that only appear in production on Railway, Vercel, VPS, and similar environments. That is actually the most common case.
How fast do you usually finish?
Single isolated bugs are usually done in 24 hours or less. Complex multi-file issues with unclear root causes take 2 to 3 days depending on how deep the problem goes.
