David is a man of many parts. He's been a consultant editor for Techworld since its launch. David currently earns a crust as a technology consultant, specialising in networking, telecomms, security and Internet application development. He has variously worked as a systems and network manager in academia and the defence industry, a full-time writer, technical director of an international test lab, head of IT for a multi-national publisher and CTO of both an Internet startup and later a venture capital organisation. When not writing copy for TechWorld or developing websites for friends and family, David's main weekend vice is spending vast amounts of money renting light aircraft to fly over the mountains of Norfolk.
