At Ozon Tech, I design and deploy Go microservices for a high-load recommendations platform serving 200K+ requests per second and 100M+ monthly users.
I built a Go service that aggregates business metrics from services via Kafka and Redis, with Prometheus and Grafana dashboards and alerts. This helped prevent multiple P1/P2 incidents.
I also developed API testing and automation frameworks, increasing coverage from 0% to 50% and reducing release time from hours to one hour. I led production incident investigations and post-mortems, reducing MTTR by 40%.
At Home Bank, I built and maintained backend test automation infrastructure and implemented proxy-based API response mocking. Earlier, at Digital League, I supported releases through regression testing, release validation, and production support.
