chris davenport

Location: Shrewsbury, Shropshire, United Kingdom
Timezone: GMT
Position: Production Leadership Team

Born 1958, Chris first began programming on a DEC PDP8 in 1975. He gained a degree in mathematics in 1979 and, after a brief spell as a mathematician in the aerospace industry, got sucked into the rapidly growing computer industry. Chris has developed software at all levels from assembly language upwards, on everything from microprocessors to mainframes, and has learnt through hard experience the value of good, disciplined commenting and thorough documentation. "Documentation is as much a part of the finished product as the code itself."

He discovered Mambo in 2003 while searching for a content management system for an intranet project. Although impressed by the product itself, he felt that the lack of documentation was a major weakness. Rather than complaining, he set about trying to fix the problem by writing his own and was soon recruited to the Documentation Team. He switched to Joomla as soon as the split occurred and is now responsible for developer documentation.
