What I'm looking for

I seek backend or full-stack roles focusing on Java/Spring microservices, secure integrations, collaborative Agile teams, professional growth, and measurable product impact.

I am a solution-driven developer with strong Java and Spring expertise, experienced in building microservices, RESTful APIs, and e-commerce platforms. I have delivered production projects using Agile/Scrum, collaborated with cross-functional teams, and applied best practices such as testing with JUnit/Mockito, CI/CD, and design patterns to improve productivity and product quality.

My work includes designing data models, integrating third-party payment and authentication (OAuth2/OpenID/Keycloak), implementing security and email services, and using technologies like Spring Boot, Spring Cloud, Docker, Kafka, MongoDB, and PostgreSQL. I focus on maintainable, reusable code and measurable outcomes—such as increased productivity and improved UX—while supporting operations and resolving customer issues.
