At Querify Labs (CedrusData) he made substantial Trino enhancements, including a Cascades-style exchange planner, dynamic catalogs, partition-aware planning, and gpfdist support, and is a Trino contributor. Now back at JetBrains, he continues to bridge advanced algorithms and scalable systems, with a strong academic foundation from Saint Petersburg State University and ITMO.
