About this gig

Java Spring Boot backends & microservices


I build production-ready backends in Java with Spring Boot REST APIs and microservices that are clean, testable and ready to scale.


What I build:

  • REST APIs with Spring Boot & Spring Web
  • Security with Spring Security (JWT, roles)
  • Data layer with Spring Data JPA / Hibernate PostgreSQL, MySQL, MSSQL
  • Microservice architecture, DTOs, validation, proper error handling
  • Unit & integration tests (JUnit)


You get: a well-structured Maven/Gradle project, clear layering (controller / service / repository), and a README so anyone can run and extend it.


New service from scratch, new endpoints on an existing Spring app, or cleaning up an inherited codebase all good.


I can Dockerize & deploy the service so it's actually running, not just compiling.


Tell me what the service should do and I'll propose a clean Spring Boot design.
