Nigel Bayliss, Optimizer Product Manager
I'm the product manager for the Oracle Optimizer. I started out as an Oracle DBA and application developer in 1988, gradually migrating to the field of consulting, specializing in database design and performance management. I joined Oracle Consulting in 1996 where I concentrated on delivering performance-critical, very large database applications. Since then, I've been involved in a wide variety of different roles including development, benchmarking and pre-sales (with a particular emphasis on Oracle Exadata). I am part of the Oracle Data Warehouse Product Management team.
