Shaun has been working with PostgreSQL since late 2000. He presented in several past Postgres Open conferences from 2011 to 2017 on topics such as handling extreme throughput, High Availability, server redundancy, failover techniques, system monitoring, and cluster management. He's also the author of the PostgreSQL High Availability Cookbook, which he wrote to make life easier on DBAs using PostgreSQL in Enterprise environments.
Currently he serves as a consultant at 2ndQuadrant, a Postgres services and development company where he ensures clients have a great Postgres architecture, and maintains his PG Phriday blog.
Ultimately, he wants to prove PostgreSQL is more than ready for major installations.
