I will fix nestjs production apis and backend bugs

Your NestJS or Node API is broken, slow, or missing an endpoint and you need a production fix, not a rewrite.

I work on live backends: REST, webhooks, auth, MongoDB or PostgreSQL, queues, and third-party APIs (payments, marketplaces, Excel imports).

What you get

A clear repro of the bug or the missing API behavior

A focused patch in your repo (NestJS preferred, Node/TypeScript OK)

What changed and how to verify it

Good fit

500 / 401 / 404 / timeout on an existing route

Webhook not firing or payload mapped wrong

One new endpoint on an existing module

AI-generated NestJS that compiles but fails in real use

Not included

Full app rewrite or new product from scratch

Frontend / React / mobile

DevOps, servers, or 24/7 on-call

Sharing production secrets in chat use a sanitized .env.example

Message me before you order: repo (or zip), the broken route, and the expected result. If the scope is bigger than the package, I will say so before you pay.
