I started to work with the Oracle database using version 5 in 1989. I was 15 years Oracle employee and finally ended up as member of the Real World Performance Group as principle member of technical staff. In 2012 i left Oracle and became Oak Table Member and somewhat later, Oracle ACE. I would call myself an Oracle Performance Architect. My intentionis always to make software work more efficiently. I will do whatever it takes. Be it a change in the data model, the physical design, the code, the database setup or even the hardware. I always believe in scientific methods. I disregard guessing and I favour facts. I hold a US patent in improving certain queries, together with my friend, Bjoern Engsig.
