I can help with:
REST API and response errors
Express routes and middleware
NestJS controllers, services, and modules
Async/await and Promise issues
Authentication and permission bugs
Database query and data-handling problems
TypeScript build and runtime errors
Dependency and configuration issues
Error handling and backend stability
Every order includes bug investigation, a verified code fix, and clear fix documentation according to the selected package.
Before ordering, please send the code, reproduction steps, error logs, expected behavior, Node.js version, dependencies, and environment details.
I only work on systems and code you own or are authorized to modify. Please message me before ordering so I can confirm the scope.
