What I'm looking for

I’m looking for a backend Java role where I can build secure, scalable, high-performance systems—focused on performance optimization, system reliability, and long-term maintainability. I want to work on microservices, reactive architectures, and real-time features.

I’m a Backend Java Developer with over 4 years of professional experience designing, developing, and maintaining scalable, secure, and high-performance systems. I’m driven by “programming and continuous learning,” and I enjoy tackling complex challenges with “innovative and efficient solutions.”

Across enterprise projects, I delivered secure RESTful APIs and microservices, implemented complex workflows with Camunda 8 (multi-step Task/User Task with dynamic conditions), and improved reliability with robust error-handling and retry strategies. I also built reactive backend services with Spring Boot and WebFlux, integrating Spring Security (JWT), RabbitMQ, WebSocket, and geospatial processing with PostgreSQL/PostGIS—supporting thousands of concurrent real-time events while keeping latency low.
