Leads engineering for Postgres managed by ClickHouse, one stack for transactions and analytics, along with database integrations: Postgres and MySQL CDC in ClickPipes, and the open-source mcp-clickhouse server.

Co-founded PeerDB (YC S23) to make Postgres replication fast, simple, and cost-effective: a native CDC and ETL platform built in Go on Temporal, streaming Postgres to data warehouses, queues, and storage. Acquired by ClickHouse in 2024; it now powers ClickPipes for Postgres.
