I will fix nodejs, express and typescript bugs, errors and rest api issues
Muhammad Rizwan
About this gig
Is your Node.js backend crashing, throwing errors, or refusing to deploy? I fix Node.js, Express and TypeScript bugs fast - and explain what caused them, in plain words.
WHAT I FIX
- Runtime errors, unhandled exceptions and crashes
- Express middleware, routing and async/await issues
- TypeScript type errors and build failures
- REST API bugs: wrong responses, status codes, validation
- Database query errors (PostgreSQL, MongoDB)
- Authentication issues (JWT, sessions)
- Deployment and environment problems (PM2, Docker basics)
HOW IT WORKS
1. You send the error, logs or repo access
2. I reproduce the bug locally
3. I fix it, test it, and show you the change
4. You get a short summary of the root cause
Clean, commented fixes - no hacks that break again next week. Message me before ordering if you are not sure the issue fits - I will tell you honestly.

FAQ
What do you need from me to start?
Your code (GitHub repo or zip), a description of the bug, and steps to reproduce it.
What if the bug cannot be fixed?
If I cannot fix it, you get a full refund — no risk to you.
Do you work with frontend bugs too?
My focus is Node.js/TypeScript backends. For React frontend bugs, message me first and I will tell you if I can help.
What do you need from me?
The error message/logs and access to the code (GitHub invite or a zip). The more detail, the faster the fix.
What if the bug is bigger than expected?
I stop, show you what I found, and quote honestly before doing extra work — no surprise charges.
