Ich werde deine Java Spring Boot REST API erstellen oder reparieren

Java backend developer working professionally since March 2025. I build and maintain REST APIs with Java and Spring Boot, using Spring Data JPA/Hibernate, PostgreSQL, Spring Security with JWT, and unit tests with JUnit and Mockito. I also set up CI/CD pipelines with GitHub Actions and Docker, and deploy applications on Linux servers with Docker Compose, Nginx and HTTPS. I communicate clearly in writing, in Spanish and English, and I deliver clean, tested code. Message me before ordering so we can confirm scope.
