David N. Welton lives in Innsbruck, Austria, with his wife Ilenia and daughter Helen, after a number of years in Padova, Italy. His personal web site is http://www.welton.it/davidw/ and his business web site is http://www.dedasys.com.

Jacques Le Roux has been in the IT business since September 1985. Since then, he has worked mostly on PCs but also on Mainframes in the eighties. For many years he used the APL language as his preferred language. In the mid nineties, he switched to C++, and in 2003 to Java. He likes to see himself as a self made man even if he is an IT engineer graduate from CNAM in Paris (a highly regarded French Open University). During this period, he worked for major French companies in various domains (bank, insurance, TV broadcasting, Media-planning, nuclear energy and manufacturing).
Since 2000, Jacques has been working independently for his own Company "Les Arts". Looking for open source Point of Sale software, he crossed the OFBiz project when it was not yet an Apache project, in September 2004. Since early 2005 he has contributed to the project and OFBiz is now his main source of income. He utilises his skills across the whole life-cycle of a project: doing POC as a pre-sales consultant, helping companies in their analyses and doing implementations when needed.
