Working with RDBMS since Sybase 4.x / "Ashton-Tate Microsoft" SQL Server, I have designed and built transactional database systems for applications ranging from Wells-Fargo Foreign Exchange to list-processing AI recommendation systems. Recently focused on MySQL variants performance and scalability, I worked on Percona for 3 years creating Fabric-managed sharded databases for OLAP applications on the bleeding edge. Now globally supporting database customers.
