About this gig

Looking for a reliable Java Spring Boot developer to build your backend? I've got you covered.


I build clean, well-structured REST APIs and backend systems using Java, Spring Boot, and Spring Data JPA. Whether you need a simple CRUD API or a more advanced setup with authentication and multiple services, I can handle it.


What I offer:


REST API development with Spring Boot & Spring Data JPA

JWT authentication & Spring Security implementation

Microservices architecture (Spring Cloud, Kafka, RabbitMQ)

Database integration - PostgreSQL, MySQL, MongoDB

Docker containerization

Clean, documented code with Postman collections


My background:


I've built a microservices fitness platform, a banking system with the SAGA pattern and Kafka, and a Chrome Extension powered by Spring Boot and Gemini AI. I also have a pull request merged into a live open-source Spring Boot project, reviewed and approved by the maintainers.


New to Fiverr, but not new to backend development. I communicate clearly and keep you updated throughout the project.
