What I'm looking for

I seek senior backend or full-stack roles using Java and Spring in collaborative teams with CI/CD practices, opportunities to design scalable microservices and impact product stability.

I am a Senior Software Developer with over 8 years of professional experience focused on Java development and full-stack delivery. I hold Oracle Java SE 8 certification and have consistently designed and implemented backend systems, microservices, and frontend features.

I have delivered projects across banking, e-commerce, IoT, and education sectors, owning both frontend and backend responsibilities, and working with Spring Boot, Spring Cloud, REST, and modern JS frameworks such as Angular and Vue.js.

My technical practice spans CI/CD (GitLab, Jenkins, Nexus), containers (Docker), messaging and integration (MQ, Camel), search (Elasticsearch, Solr), and multiple databases including MySQL, PostgreSQL, Oracle, MongoDB, and Cassandra.

I communicate effectively in English and Russian, work well in remote and cross-functional teams, and focus on writing maintainable, testable code that stabilizes and scales production systems.
