Paul Butcher started out writing games for 8-bit home computers before he was a teenager, and since then has worked in diverse fields at all levels of abstraction, from microcode on bit-slice processors to high-level declarative programming and all points in between. He's been using agile approaches for the last several years, although had adopted many of the same techniques before the agile movement gave them a name. Paul's depth of experience derives from a history of working for startups in which he's had the privilege of working with several great teams on cutting edge technology. In an attempt to demonstrate that he's at least as fast as Lewis Hamilton, Paul totaled his race-car last… year. So no more playing with expensive toys for the time being-but he will be back on track soon!
