Project details

I am a backend engineer specializing in NestJS.
This project is for teams who already have a NestJS codebase and need:

• New features added
• Bugs fixed or production issues debugged
• API behavior corrected or optimized
• Authentication / authorization issues resolved
• Database or ORM (Prisma / TypeORM) problems fixed
• Performance or memory issues investigated

I focus on clean, maintainable code, minimal risk changes, and preserving existing API behavior so frontend integrations do not break.

Typical work includes:

 • Adding or modifying controllers, services, modules

 • Debugging request/response issues

 • Fixing guards, interceptors, pipes, or filters

 • Resolving Prisma / database errors

 • Improving logs, error handling, or test coverage

This project is best suited for small to medium tasks and ongoing backend maintenance.
