John Edward Scott has been using Oracle since version 7 (about 1993) and has used basically every release since then. He has had the good fortune to work on a wide range of projects for a varied group of clients. He was lucky enough to start working with Oracle Application Express when it was first publicly released and has worked with it nearly every day since (and loves it).
John is an Oracle ACE Director, was named Application Express Developer of the Year in 2006 by Oracle Magazine, and is the author of the best-selling book Pro Oracle Application Express. He is also the co-founder of APEX Evangelists (www.apex-evangelists.com), which specializes in providing training, development, and consulting specifically for the Oracle Application Express product.
