A production-ready Spring Boot 4.1 / Java 21 REST API foundation for backend developers who want to skip weeks of boilerplate. Includes JWT authentication, PostgreSQL with Flyway migrations, 30 tests using Testcontainers, Docker setup and CI pipeline. $29 one-time purchase, full source code.

I kept rebuilding the same auth, migrations, testing and Docker setup on every new Java project. I packaged the production-grade baseline I use so other developers can start shipping features on day one.
