Rockstar🎓
Top SchoolVladimir Gordiychuk is a Senior Software Engineer with 11 years of experience designing and operating high-throughput distributed systems, currently driving the development of a Yandex time-series database that handles hundreds of millions of writes per second and millions of reads. He has deep expertise in Java, PostgreSQL replication, streaming architectures and performance tuning—evidenced by building a Netcracker pipeline that streams logical replication to Kafka and Elasticsearch at 10k TPS with ~2s lag. An active open-source contributor, Vladimir has improved the widely used pgjdbc PostgreSQL JDBC driver by adding configurable fetch-size and replication-related APIs, helping reduce memory pressure in client applications. He combines production-grade scalability work with low-level database and JVM optimizations, and brings a pragmatic focus on measurable performance improvements and robust testing.
