Jeff Casimir
Owner, Jumpstart Lab

I started JumpstartLab in the summer of 2009 after six years as a public school teacher and administrator. I love teaching skills that help people unlock their ideas. My primary expertise is in Ruby and Rails, but also love subjects like JavaScript, database design, and anything else related to the web.
