Informazioni su questo servizio

Is your Node.js, NestJS or .NET API throwing errors, returning wrong data, or missing a feature? Is something broken on your website? I'll find the problem and fix it with clean, maintainable code.


I'm a backend developer with 10+ years of experience building APIs, websites and business systems, including credit management and real estate platforms running in production.


WHAT I CAN HELP WITH:

- Bugs, crashes and unexpected API responses

- Database issues with SQL Server, MongoDB or MySQL

- New endpoints or small features

- Authentication and validation problems

- Next.js / React website bugs

- Swagger / OpenAPI documentation

- Python FastAPI backends


HOW IT WORKS:

1. Message me BEFORE ordering with a short description of the issue

2. I confirm the scope and the right package

3. I fix it, test it, and explain what I changed


You get the updated code plus a short summary of the fix.


Not sure if your issue fits a package? Send me a message and I'll get back to you with an honest estimate.
