About this gig

Are you looking for a reliable Java backend developer who ships clean, production-ready code?


I build full stack applications using Java Spring Boot, PostgreSQL, and REST APIs. I have real production experience building enterprise systems, integrating authentication with Keycloak, and deploying with Docker.


What I deliver:

- Spring Boot REST APIs with proper error handling

- PostgreSQL database design and optimization

- Authentication and authorization (Keycloak, JWT, OAuth 2.0)

- Docker containerization for easy deployment

- Clean, well-documented, maintainable code

- Source code included with every order


I have built production systems used daily by real users. You are not getting a tutorial project, you are getting professional-grade backend development.

I am building production systems with a focus on security and scalability. My stack includes Java 17+, Spring Boot, PostgreSQL/PostGIS, Node.js, and React. I have experience with infrastructure such as Docker, Linux, GitHub Actions, AWS, and Cloudflare Workers. I am familiar with security aspects like REST APIs, WebSocket, TLS/SSL, X25519, and AES-256-GCM.
