I will fix bugs and errors in your nodejs or nestjs code

Your Node.js or Nest.js app throwing errors? Server crashing? Endpoint returning the wrong thing? I'll fix it fast.

I debug Node.js, Nest.js, Express, MongoDB, PostgreSQL, and AWS issues for a living. Most bugs are fixed within hours of ordering.

COMMON ISSUES I FIX

Server crashes and unhandled promise rejections

MongoDB / Mongoose query and aggregation errors

Authentication / JWT / cookie issues

CORS, environment config, deployment problems

Memory leaks and performance bottlenecks

Broken API endpoints returning wrong data

Stripe / payment integration errors

Socket.io connection and real-time bugs

AWS deployment failures (EC2, Lambda, S3)

Docker container issues

Failing tests

AI-generated code that "almost works" but doesn't

WHAT YOU GET

Root cause explained in plain English, not just a code patch

Fixed code with comments so you understand what changed

A short note on how to avoid the same bug next time

TO ORDER QUICKLY

Send me your error message, repo access (or relevant file), and a short description of what should happen vs what is happening. I'll confirm if I can fix it, give you a time estimate, then start.

I've shipped fixes within 30 minutes of ordering for small issues.
