ORACLE

I'm specialized in Oracle Database performance troubleshooting. I'm among the top specialists worldwide in the area of SQL performance analysis and Oracle optimizer technology... I regularly publish notes on my blog and share my knowledge via video tutorials on my Youtube channel, free webinars and contributions to the official Oracle OTN forums. I'm also regularly invited to speak at user conferences around the world... As acknowledgement of my contributions to the Oracle community I was invited to join the Oracle ACE program in 2009 and became Oracle ACE Director in 2011. In December 2016 I've asked to be removed from the ACE program and since then have "Alumni" status.
