Perhaps in a past life you were a mechanical engineer or energy modeler that was drawn into the intriguing world of web programming and software development long ago. Maybe you have a degree in physics or mathematics but somewhere along the way you became more excited about creating the software tools rather than using them. Or possibly you’re just a really talented web developer that drives a Prius and loves to recycle. You are now an encyclopedia of programming knowledge and web wisdom accrued over the years. So what’s missing? Maybe you’ve been working at Internetz Inc. where you and a horde of other developers try to maximize the clicks while hanging on for that mercurial, next round of VC funding. Somewhere in the back of your mind, you wonder if it might be possible to put your skills to good use for a higher purpose… What if you could enjoy the challenge of interesting, creative work, while also having a meaningful impact on the planet?
