Are you experiencing Node.js backend errors, broken REST APIs, authentication problems, or database issues? I can help you debug and fix your existing backend application.

  • Broken REST API endpoints
  • HTTP 400, 401, 403, 404, and 500 errors
  • Request validation and error handling
  • JWT authentication and authorization issues
  • MongoDB and PostgreSQL query or connection errors
  • Prisma ORM errors and database-related bugs
  • Incorrect API responses and business logic issues
  • Backend integration and configuration problems
