Andres is one of the leading contributors in the Postgres community and his work has been influential to advancing the replication, performance and scalability capabilities of Postgres. He joins EDB from Citus Data, Inc., where he was a Developer and Principal Software Engineer for two and a half years. Prior to that, he was a Developer and Consultant for 2ndQuadrant Ltd. for just over three years. He spent two years as a Developer and Software Architect at Programmfabrik GmbH in Berlin. He also ran his own database consulting company, Freund EDV, for 13 years. Andres is known in the Postgres community as the primary author of logical decoding, which was introduced in PostgreSQL 9.4 and became the basis for logical replication in Postgres. He has also done major development work to enable Postgres to scale to large systems, especially multi-socket systems. Most recently, for the PostgreSQL 10.0 release, he rewrote Postgres’ entire expression evaluation engine. The result is a significant increase in speed on queries that evaluate a large number of rows.
