Sean Levy: Software Developer

Over the past ** years I have lived and worked in Southern California,

Pittsburgh, Boston and Portland in settings ranging from high-level

academic research to high-pressure dot com chaos. I focus exclusively

on telecommuting work arrangements and coordinate with my clients and

colleagues over the Internet.

I am self-motivated, used to producing substantial volumes of work on

my own, am adept at reverse-engineering existing work and fixing

hard-to-find bugs and have a proven track record of being productive in

teams that are geographically dispersed.
