What I'm looking for

I seek senior backend roles focused on Java microservices, cloud-native platforms, and collaborative agile teams that value architecture, quality, and continuous delivery.

I am a Senior Java Software Engineer with over 13 years of experience delivering robust backend solutions across healthcare, banking, and telecom sectors. I hold Oracle Java certifications and have led development using Java SE/EE, Spring Boot, Quarkus, microservices, hexagonal architecture, and extensive CI/CD practices.

I consistently apply agile (Scrum) practices to deliver high-quality software, leveraging Docker, Kubernetes, AWS, and modern testing frameworks (JUnit, Mockito). I have contributed to architecture, data modeling, stakeholder collaboration, and maintenance of critical systems for major clients.
