I will fix bugs and errors in your node js express backend api
Younes H
About this gig
Is your Node.js backend throwing errors, crashing, or just not behaving the way it should? I can help.
I'm a backend developer specializing in Node.js, Express, PostgreSQL, and Prisma. I build and debug production-style backend systems including a custom API Gateway with load balancing, circuit breakers, and Redis rate limiting, and a full-stack booking platform with JWT auth and race-condition-safe transactions.
What I can fix for you:
API errors and unexpected crashes
Authentication/authorization (JWT, sessions) issues
Database bugs bad queries, race conditions, wrong relations
Broken endpoints or incorrect HTTP logic
Performance issues (slow queries, missing indexes, no caching)
Docker/deployment configuration problems
How I work:
- Send me your code (or repo access) and describe the issue
- I diagnose the root cause not just a patch, the actual "why"
- I fix it and explain what caused it, so it doesn't happen again
I care about clean, maintainable fixes not band-aids that break again next week. Message me before ordering if you're not sure which package fits your issue, happy to take a quick look first.

FAQ
What do you need from me to get started?
Access to your code (GitHub repo, zip file, or relevant files) plus a clear description of the bug or error, including any error messages/logs if you have them.
What if my issue isn't listed in the package descriptions?
Message me first with details before ordering — most backend issues fall under debugging/fixing, and I'll tell you honestly if it's a good fit or point you elsewhere.
Do you sign NDAs or work with private repos?
Yes, I'm happy to sign an NDA and work with private repositories or limited-access code.
