Backend Java developer specializing in microservices, BPMN systems, and scalable Spring-based architectures.

I am a Backend Java developer with 5+ years of commercial experience focused on building scalable server-side systems using Java, Spring, and microservices. I have strong domain experience delivering large-scale projects for government institutions and retail corporations, including migrations from monoliths to microservices.

I design and implement BPMN-driven business workflows, REST and event-driven services, and work with PostgreSQL, OracleDB and MySQL while leveraging CI tools like Docker, Maven/Gradle and Git. I have hands-on experience with testing using JUnit5 and Mockito, messaging with RabbitMQ, and search with Apache Solr.

I have mentored junior engineers, led an internal English-speaking club, and contributed to cross-functional teams to modernize legacy systems; I am seeking a remote position with an international company where I can continue to improve maintainability and mentor teams.
