About this gig

Need a clean and secure Spring Boot backend for your SaaS, MVP, admin panel, internal tool, or business application?


I will build a maintainable Java/Spring Boot REST API with JWT authentication, PostgreSQL integration, clean endpoint structure, validation, Swagger/OpenAPI documentation, Docker setup, and handoff notes depending on the package you choose.


What I can help with:


- Spring Boot REST API development

- JWT authentication and role-based access

- PostgreSQL database integration

- Swagger/OpenAPI documentation

- Docker or Docker Compose setup

- Backend validation and error handling

- Clean project structure and README handoff
