Rockstar🎓
Top SchoolAndrew Pogrebnoi is a Principal Software Engineer with 11 years’ experience building high-performance, reliable distributed systems and storage solutions, currently working on PostgreSQL encryption and backup tooling at Percona. He combines deep systems expertise—compilers, databases, performance tuning—with hands-on operator and DevOps work, contributing to widely used projects like Percona's MongoDB and XtraDB Cluster operators. Previously he architected a geo-distributed RTB platform processing 50k QPS per node, shaving CPU by up to 50% with custom in-memory storage and driving sub-millisecond bid selection at the 99th percentile. Based in Limassol, Cyprus, he focuses on stability, maintainability and low-latency design, and often surfaces subtle SDK and nil-reference edge cases in production-grade operator code.
