What I'm looking for

I seek backend/API roles where I can design and integrate secure RESTful services, improve test coverage, work with containerized deployments, and contribute to scalable systems and team best practices.

I am a Java backend developer with hands-on experience designing and integrating API-based applications and microservices. I focus on building secure, performant RESTful APIs using Spring Boot and related Java technologies.

At Qinshift and client engagements I implemented end-to-end integrations, authored API documentation, and maintained evolving services to meet business needs. I emphasize code quality through test-driven practices and comprehensive unit test coverage.

My tech strengths include Java (8/11/17), Spring Boot, Hibernate, JPA, Vaadin for web UIs, containerization with Docker, and relational databases such as MySQL and PostgreSQL. I also work with CI/build tools like Maven and Gradle and source control with Git.

I hold certified Vaadin credentials and Docker/Java course certificates, and I seek roles where I can deliver reliable APIs, improve system integrations, and mentor testing best practices.
