Java Backend Developer (Software Engineer)

На данный момент Java Backend Developer.

Мои компетенции и опыт

Over 5 years of commercial Java backend experience across fintech, industrial monitoring, and edtech. Built and maintained high-load microservices using Java 8–21, Spring Boot, Kafka, and PostgreSQL.

At Sberbank, worked on a high-load banking platform for salary card issuance — increased TPS by 40% through connection pool tuning, resolved chronic Kafka consumer rebalancing issues, eliminated 12 security vulnerabilities found during internal audit, and integrated the service with 4 internal banking APIs.

At ACT, led a full modernization of a legacy system: migrated from Java 8 to Java 21, redesigned core database schemas and cut P95 query latency from 850ms to 140ms, rebuilt authentication from scratch using Spring Security 6 + JWT, and delivered 3 new domain modules end-to-end.

Earlier projects covered edtech and corporate portals — built file management services, RBAC systems, async event processing with RabbitMQ, and REST APIs from scratch.

Comfortable working in both legacy codebases and greenfield projects. Always focused on measurable outcomes — performance, stability, and clean architecture.
