In plain English

This project is a complete login system that lets users create an account, log in, log out, and refresh their session securely. It's similar to what modern websites use to protect user access and ensure your data stays safe. The API manages user identities while preventing unauthorized access.

For the curious

Built with Spring Boot and PostgreSQL, the project implements full JWT authentication with access tokens, refresh tokens, and a blacklist mechanism. It follows a clean architecture using Models, DTOs, Repositories, Services, Controllers, and dedicated configuration/security layers. CI/CD pipelines and Docker Compose ensure reproducible environments and automatic deployment. Unit tests validate core features, and complete CRUD flows are implemented for user management.

A little summary :

This authentication API is a solid foundation for secure backend systems. It demonstrates mastery of Spring Security, token-based authentication, Dockerized infrastructure, clean architecture, and CI/CD workflows. Designed in only three days, it reflects efficiency and a strong understanding of production-grade best practices.
