I develop and optimize backend systems using Java and Spring Boot. I can build REST APIs, fix performance issues, implement JWT and SSO authentication, and handle database integration. My focus is on clean, scalable, and production ready code with proper validation, logging, and error handling.
If you want a sharper version:
I build and fix Spring Boot backend APIs that are fast, secure, and production ready. From authentication and database integration to performance optimization, I focus on delivering reliable backend systems that actually work under real usage.
