Over deze dienst

Already have a Spring Boot API but no authentication yet?

I will integrate a complete JWT authentication system into your backend clean, secure, and ready for production.


What I implement:

  • Login and register endpoints with JWT token generation
  • Secure password encryption with BCrypt
  • Spring Security configuration with protected routes
  • Role-based access control (admin, user, or custom roles)
  • Token validation and expiration handling


This is not a tutorial copy-paste. I implement authentication the way it works in real applications with proper filter chains, exception handling, and security layers.


Every delivery includes full source code, Postman collection with ready-to-use auth requests, and a README explaining the full auth flow.


Message me before ordering to confirm your project is a good fit.
