About this gig

Is your NodeJS or NestJS backend crashing, failing to start, or blocking deployment?


I will fix blocking NodeJS / NestJS bug and clearly explain the root cause,

so your application runs correctly again.


This gig is focused on fast, safe bug fixing no unnecessary refactors,

no risky changes, and no guesswork.


I work on live production backends and complex workflows, so every fix is

tested and handled carefully.


I can help with:

  • API crashes and runtime errors
  • NestJS module, dependency injection, and configuration issues
  • Authentication / authorization bugs (JWT, RBAC)
  • Production bugs after deployment
  • Database-related backend bugs (PostgreSQL / TypeORM)


Youll get a clean fix, a clear explanation, and guidance to avoid the issue again.

I specialize in critical backend bug fixes in Node.js & NestJS systems. I routinely fix authorization leaks (JWT/RBAC), production API crashes, third-party API failures (Plaid, Checkr, Attom), and real-time chat issues like message duplication or ordering bugs. I work directly on live systems and focus on safe, production-ready fixes.
