Kirill Rysin is an SDET with 8 years of experience designing test automation, CI/CD and analytics pipelines to improve product quality and developer feedback loops. Based in Belgrade, he has led QA teams at Yandex and built service-wide testing strategies, crowdtesting optimization, and scalable test analytics that revealed process bottlenecks. At YDB he combined DevOps and automation expertise to modernize GitHub Actions pipelines, surface real-time test results in PRs, and drive a 75% reduction in muted tests in three months. He is fluent in Python, SQL and BI tooling and has a track record of eliminating CI performance bottlenecks and automating mute management with auto-ticketing and historical failure tracking. An underrated strength is his focus on measurable ownership—translating test health into dashboards and SLAs that nudge teams to act. His open-source contributions to the YDB distributed SQL project reflect practical experience with high-availability, scalable systems.
