I've built resilient, high-load distributed systems across fintech, HealthTech, and enterprise software, with more than four years of commercial Java development experience.

At a large Eastern European fintech and banking ecosystem, I deployed Kafka-based StandIn database replication for near-100% uptime and zero data loss during updates. I also reduced database disk usage by 23.9%, cut infrastructure overhead by 9%, and built monitoring that reduced production anomaly detection time by 50%.

At RESHENIE-SOFT, I migrated a legacy PL/SQL monolith to a Java/Spring Boot gateway and supported an Oracle-to-PostgreSQL transition. I redesigned a REST API around Kafka-driven asynchronous messaging, tripling message throughput, and raised test coverage from 12% to 78%.

Earlier at EPAM, I co-developed a microservice application from scratch using Spring Boot and Spring Data JPA, containerizing services with Docker and integrating CI/CD. I enjoy taking systems from requirements through automated releases, observability, and reliable production operation.
