Experience
Site Reliability Engineer · Yandex
Improved update download speed ~3x by optimizing internal caching and network layer, reducing user session startup time. Migrated GPU virtual machines to a new architecture and driver branch, ensuring seamless user transition and improved VM performance. Reduced user disk mount time from 5-7 seconds to ~0.5 seconds by switching to Windows system APIs, eliminating backend service timeouts. Automated integration and updates of external gaming platforms, cutting manual operations and accelerating new game releases to production. Reduced infrastructure error rate on backend from thousands per day to zero by analyzing Windows interactions and golden image build process. Standardized release processes and documentation (including game documentation generation), simplifying onboarding of new projects. Mentored new team members, conducted onboarding sessions and technical knowledge-sharing meetings.
