I wear a couple of hats, professionally speaking. I am a full-time employee of Quest Software, and have been since 2001. My official title is "PL/SQL Evangelist." I came up with it myself. It was either that or "PL/SQL Obsessive/Compulsive." "Evangelist" is a bit more dignified. I do lots of different things at Quest, most importantly (from my perspective, anyway) designing and developing the backend of Quest Code Tester for Oracle.
I also offer training and consulting through my own firm, Feuerstein and Associates. Choose from any of the following to get in touch with me regarding the hiring of my services at your company or with your user group.
