Dave Hoover is the Chief Craftsman at Obtiva where he helps lead Obtiva's Software Studio and apprenticeship program. Dave has been developing software since 2000, when he left a career in child and family therapy. In 2002, Dave read Pete McBreen's "Software Craftsmanship", which re-framed Dave's understanding of software development and how people become great software developers. Dave has become increasingly passionate about learning and has dedicated several years of his career to thinking, writing, and speaking about apprenticeship. Over the last couple years, on most days, you'd find Dave coding Ruby and Rails as the lead developer for Mad Mimi, one of his clients at Obtiva. Dave also enjoys all sorts of endurance sports.

Adewale Oshineye is an engineer at a little-known search engine named Google. This is a consequence of many deeply geeky evenings spent programming 8-bit computers when he was a child. When he grew up Adewale somehow fell into IT consultancy. His career at consultancies such as Thoughtworks gave him the chance to work on projects ranging from point-of-sale systems for electrical retailers to trading systems for investment banks. It also gave him a chance to learn from some of the most interesting software craftspeople in Western Europe. In those rare moments when he's not in front of a computer he can be found behind a digital camera somewhere in London.
