Dimitri Gielis was born in 1978. Together with his family he lives in Leuven, Belgium.
At an early age, Dimitri started experimenting with computers (Apple II and IBM XT), and he quickly got to know that he would like to work with computers and especially with databases all his life.
In 2000, Dimitri began his career working as a consultant for Oracle Belgium where he came across almost every Oracle product. His main expertise was in the database area, but at that time he was also exposed to HTMLDB, which was renamed as Oracle Application Express later on. From the very start he liked the Oracle database and APEX so much that he never stopped working with it. Dimitri then switched to another company to create an Oracle team and do pre-sales, to later create and manage an Oracle Business Unit.
In 2007, Dimitri co-founded APEX Evangelists (http://www.apex-evangelists.com), together with John Scott. APEX Evangelists is a company that specializes in providing training, development, and consulting specifically for the Oracle Application Express product.
On his blog (http://dgielis.blogspot.com), he shares his thoughts and experience about Oracle, and especially, Oracle Application Express.
Dimitri is a frequent presenter at OBUG Connect, IOUG Collaborate, ODTUG Kaleidoscope, UKOUG conference, and Oracle Open World. He likes to share his experience and meet other people. He's also President of the OBUG (Oracle Benelux User Group) APEX SIG.
In 2008, Dimitri became an Oracle ACE Director. Oracle ACE Directors are known for their strong credentials as Oracle community enthusiasts and advocates.
In 2009, Dimitri received the APEX Developer of the year award by Oracle Magazine.
In 2012, Dimitri was part of the LA OTN Tour where he presented different APEX topics.
