Forbes (Aug. 23) -- Two years ago Roger Dickey, 33, started San Francisco-based Gigster, a platform where companies hire freelance software developers. Its selling point: a heavily screened pool of top developers eager to moonlight on a project basis for non-tech clients. I’ve been coding since I was seven years old. I studied engineering at the University of Illinois at Urbana-Champaign. I founded a company when I was 23 and created a video game called Mafia Wars, which I sold to Zynga. The game did $1 billion in revenue after I sold it.
