What I'm looking for

I'm looking to build high-quality, scalable backend applications in collaborative international Agile teams, solve complex technical challenges, and continue expanding my expertise with modern technologies.

I've built scalable backend and full-stack applications at DataArt for international financial services, e-commerce, and logistics automation clients. My work spans Java, Spring, React, Hibernate, PostgreSQL, BigQuery, and AWS.

I design REST APIs, integrations, and asynchronous messaging with RabbitMQ, while supporting reliable delivery through testing, Docker, Kubernetes, and CI/CD. I enjoy collaborating in international Agile teams and solving complex technical challenges.
