Arjen initially started with C programming, but has since branched out to other stuff that blends geekness with more human interaction.

Arjen was employee #25 at MySQL AB (2001-2007), dealing with Documentation, Community Relations, Training, Support, Licensing, and acting as Program Chair for the 2005 and 2006 MySQL Users Conferences. He also co-authored the 2nd edition of O’Reilly’s popular “High Performance MySQL” book.

Arjen founded Open Query, delivering affordable remote and on-site MySQL support and training. He also does some coding again with the OQGRAPH engine, and his work on OurDelta (Builds for MySQL & MariaDB).

Outside work Arjen likes spending time with his daughter, bushwalking, camping, and dabbles in organic gardening.
