Contact me GitHub

I'm a Golang backend developer with 8+ years of experience. I've worked at three companies — Raiffeisenbank, Kaspersky Laboratory, and ITV | AxxonSoft — building microservices and high-load systems.

My core stack is Go and Python, with solid experience in databases — PostgreSQL, ClickHouse, and Redis. I design event-driven architectures, work with Kafka and gRPC, and care a lot about performance and clean code.
