What I'm looking for

I want to lead end-to-end delivery of cloud-native Java microservices—owning architecture and features—while building high-performance REST/GraphQL backends with Kafka and Redis in a collaborative Agile team.

I’m a Senior Java Developer with 4+ years of experience in building scalable, high-performance backend systems. I architect cloud-native microservices and design complex event-driven solutions using Java, Spring Boot, and Apache Kafka.

I’ve delivered robust RESTful and GraphQL APIs, optimized data persistence in MySQL and MongoDB, and implemented high-load caching strategies with Redis. I focus on clean architecture, SOLID principles, and TDD to keep systems maintainable and high-quality.

At EPAM Systems, I lead technical design, drive CI/CD practices, and mentor developers through code reviews and technical interviews. I take complete ownership of features end-to-end—from initial design and TDD-based development to deployment and production support—while working collaboratively in Agile environments.
