Worked with databases since 2005, first as a developer, and later as an Administrator. I've specialized in MySQL since 2011, and joined Yelp in 2013 as the second DBA. Since then I've specialized in performance monitoring, benchmarking, and configuration management both with physical hardware (FusionIO) and in the cloud. My work has extended to implementing many opensource projects internally to advance our ability to scale and manage an ever growing infrastructure footprint. Recent projects include quantifying impacts of traffic patterns on database performance on various EC2 instance types, and identifying failure points with the use of a multidimensional metrics system based around cluster membership and database server roles.
