Affiliation: Cofounder, CEO, CTO, Pear Deck
I create ed tech in Iowa City. My first business and software product, ActiveGrade, was acquired in January of 2013, and I've just started a new venture called Pear Deck.
My specialties (these days) are in entrepreneurship and distributed web-app architecture. I've also directed a summer camp and taught high school. The math teacher blogosphere is what really supported me in my professional development: http://larkolicio.us/blog
