I will fix bugs in your nodejs api, express, python, flask api and application

Is your Node.js or Express app throwing errors you can't figure out? I'll find and fix the bug quickly and cleanly.

I can fix:

API routes not working or returning wrong responses

MongoDB / Mongoose query errors

Authentication & middleware issues (JWT, sessions)

WebSocket connection problems

Server crashes and unhandled errors

Environment variable and deployment issues

What I need from you:

Your code (GitHub link or zip file)

A clear description of the bug

Any error messages or logs

What you'll get:

Fixed, working code

A short explanation of what was wrong and what I changed

Fast delivery most bugs fixed within 24 hours

I'm a backend developer with hands-on experience in Node.js, Express, MongoDB, Redis, and WebSockets. I don't just patch I fix it properly.

Message me before ordering if you're unsure whether I can help. I'll be honest with you.
