About this gig

I'll build you a Java backend that's ready for real traffic not a tutorial demo.


WHAT I DELIVER

Spring Boot REST APIs (Spring Boot 3, Spring Security, JPA / MyBatis)

JWT authentication & role-based access control

MySQL + Redis integration (caching, sessions, rate limiting)

Netty TCP gateways & custom protocol servers - a rare skill; most sellers can't do this

Clean layering: controller / service / repository, DTOs, global exception handling

Swagger/OpenAPI docs + a Postman collection so you can test immediately


TYPICAL PROJECTS

CRUD modules and full microservices

Bug fixes and refactoring of messy codebases

Performance issues: slow endpoints, connection leaks, thread safety

Third-party API integration (payment, SMS, push)


WHY ME

I run production Java services under real load. My code comes documented, with a README explaining the design decisions, so your team can extend it confidently.


MESSAGE ME BEFORE ORDERING with your requirements doc or a rough description. I'll confirm scope, timeline, and the right package for you.
