I will nodejs code debug, fix bugs and errors in your backend api
ghayoorusman
About this gig
Your Node app throws an error you can't trace. The logs say nothing useful. Deploy is tomorrow.
Send it to me.
I do node.js code debug work daily:
Express APIs,
async bugs,
memory leaks,
queries that hang,
auth that works locally and breaks in production.
What I fix:
- Crashes, unhandled rejections and silent failures
- Express and REST API errors, broken routes, wrong status codes
- Async/await and promise bugs, race conditions
- MongoDB, PostgreSQL and MySQL query or connection problems
- JWT, OAuth and session auth issues
- Slow endpoints, memory leaks and blocked event loops
- Bugs in AI-generated code that looks right and isn't
Stack: Node.js, Express, NestJS, TypeScript, MongoDB, PostgreSQL, MySQL, Redis, Docker
You get the fix, a short explanation of what caused it, and code you can maintain. If the bug is a symptom of something structural, I'll tell you instead of patching over it.
I check every issue before accepting an order. Message me with your error and I'll tell you whether I can fix it and how long it takes.

FAQ
What do you need from me to get started?
Three things: access to the code (repo, zip, or just the file), the exact error message or a description of what's going wrong, and steps to reproduce it. Logs and screenshots help. That's usually enough for me to start straight away.
Can you fix bugs in AI-generated code?
Yes, and it's a big part of what I do. Code from ChatGPT, Copilot or Cursor often looks correct and then fails on edge cases, async timing, or error handling. I find what's actually broken and rewrite those parts properly.
Which package should I pick?
Message me first and I'll tell you. One clear error, Basic is enough. Several related bugs, or something you can't isolate, go Standard. If the whole backend is unstable or you inherited the codebase, Premium.
Do you work with TypeScript, NestJS and Express?
Yes, all three. Also plain JavaScript, MongoDB, PostgreSQL, MySQL, Redis and Docker. If your stack isn't listed, ask. I'll tell you if it's outside what I know well.
What if you can't fix the bug?
You get a full refund. Before that happens I'll have told you what I found and how far I got, so you're not left with nothing. I check the issue before accepting an order, which is why I ask you to message me first.
