Challenge

Many applications need a secure authentication foundation before they can scale confidently.

I built a complete auth flow with JWT, refresh-token rotation, email verification, password reset, rate limiting, and role-based access control.

Impact

The system gives any app a safer, production-minded starting point for user management and access control.
