What I'm looking for

I’m looking for a Java/Spring Boot backend role where I can build microservices and REST/WebSocket APIs, optimize performance, and ship production-ready features with JUnit/Mockito and collaborative delivery.

I’m a Java Software Engineer focused on backend application architecture and microservices development using Java and Spring Boot. I build and evolve production-ready services with clean, maintainable code and strong communication with cross-functional teams.

In my current role, I design and implement REST APIs and integrate WebSockets, leveraging Spring Cache and async messaging between distributed services. I contribute to performance optimization, problem-solving, and application stability improvements.

I also own the full post-release support loop—bug fixing, issue investigation, feature enhancements, and ongoing maintenance—backed by testable development practices. I deliver reliable code using JUnit 5 and Mockito, improving CI/CD readiness for release preparation.

I work across a modern stack (Java 11/17/21, Spring Boot/Security/Data JPA, Hibernate, and databases like PostgreSQL/Oracle/ClickHouse/Redis) and messaging/search technologies (Kafka/IBM MQ/RabbitMQ, Elasticsearch), with Docker/Kubernetes and AWS to support scalable deployments.
