I work for a company called Mast Mobile, doing mostly Ruby and Erlang.
Prior to that, I was:
A member of Dow Jones's Research and Development team, working mostly in Erlang with some Node.js.
The Optimization Team Lead at Yodle, a company in New York City that does search engine marketing for local small-to-medium businesses. The Optimization Team develops Yodle's proprietary bidding algorithm. The buzzword is "Data Science," but practically what that meant was a combination of Java, Python and R.
Before that, I worked for two startups located in New York.
