About this gig

I build secure, production-quality backend systems using Java and Spring Boot the same architecture powering real SaaS platforms.

Whether you need a REST API from scratch, JWT-based authentication, or a backend that's secure and scalable, I can help.

What I offer:

  • REST API development with Spring Boot
  • JWT/OAuth2 authentication and role-based access control
  • Database integration (MySQL, PostgreSQL, MongoDB)
  • Redis caching for faster response times
  • Clean, well-documented, testable code

Recent work:

I built a multi-service fitness tracking platform with Eureka service discovery, an API Gateway, Keycloak-secured authentication, and an event-driven RabbitMQ pipeline feeding an AI recommendation engine. I also built a full-stack task manager with JWT auth, BCrypt password hashing, and Redis-cached queries that noticeably reduced repeated database load.

I care about clear communication you'll know exactly where your project stands at every step, not just at delivery. Message me before ordering if you'd like to discuss your specific requirements, and I'll make sure the right package fits what you actually need.

Java Backend Developer specializing in secure REST APIs and Spring Boot microservices. I build production-style backend systems — JWT/OAuth2 authentication, event-driven services with RabbitMQ, Redis caching, and polyglot data layers (MySQL/MongoDB) — the kind of architecture real SaaS platforms run on. Recent work: a multi-service fitness tracking platform with Eureka service discovery, an API Gateway, and an AI-powered recommendation engine; and a full-stack task manager with JWT auth and Redis-cached queries. I write clean, testable code and communicate clearly at every stage.
