I will fix nodejs, express and typescript bugs, errors and rest api issues
Muhammad Rizwan
Over deze dienst
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.

I'm a backend developer specializing in TypeScript and Node.js. I fix bugs and build production-grade REST APIs with clean, tested code.
Recent work: implemented OpenTelemetry distributed tracing across Temporal workers for an open-source project — shared exporter package, 220+ tests green, under maintainer review.
Clear communication, on-time delivery, code you can maintain. Let's get your project working right.
Veelgestelde vragen

What if the bug cannot be fixed?
If I cannot fix it, you get a full refund — no risk to you.
