You will get a secure Spring Boot REST API with JWT, PostgreSQL, and Docker
Project details
You will get a secure, maintainable Spring Boot REST API built for your SaaS product, MVP, admin panel, internal tool, or business application.
I can include JWT authentication, PostgreSQL integration, clean REST endpoints, validation, Swagger/OpenAPI documentation, Docker setup, tests, and clear handoff notes depending on the package you choose.
What sets this project apart is my focus on production-ready backend structure, not just code that “works once.” I build with clean layers, readable naming, practical security, and maintainability in mind so another developer can continue the project easily.
I am a Principal Software Engineer and Spring Boot Architect with 13+ years of experience building backend systems, microservices, SaaS platforms, Kafka workflows, and AI/RAG features.
