I'm a gamer and developer living in Hampshire, England, and I currently work at Perforce Software as a senior development manager, managing several teams across Europe and India (as well as writing the odd bit of code when I get time). Previously I've worked in development and consulting, working on Cloud, Document Management and image processing since the mid 1990s. Before that I studied Computer Science/AI at Edinburgh University, and prior to that I wrote various games and simulations in assembler and BBC Basic.

Hobbies include gaming (computer games, roleplaying games, wargames and boardgames), reading, managing my Linux servers and programming overly complex simulations of the universe. My current projects are WorldGen and an open source RPG called YAGS.

Previously, I've worked at:

• Berkeley Software Services
• Axcelia Software
• Centrom Ltd
• Aiimi Ltd
