Rockstar🎓
Top SchoolPetr Reznikov is a senior software developer with 10+ years at Yandex, specializing in building and migrating high-performance, scalable network and data services. He led the zero-downtime migration of Yandex.Mail from Oracle to PostgreSQL across 300+ TB and 10M DAU, and designs data-driven systems that balance reliability, cost and operational constraints. Comfortable across C++, Python, OLTP/OLAP databases, stream and batch processing, he moves systems from monoliths to service-oriented architectures while enabling continuous delivery. Petr focuses on aligning technical choices with business impact—whether designing long-term storage schemas or running research-driven experiments—and has a practical knack for automating complex, resource-sensitive processes. Notably, he reduced operational overhead by eliminating DLL/ABI issues through static linking and build caching, accelerating deployment and platform upgrades.
