Full-stack Rails guy since 2004, specializing on the back end but also quite handy on the front end. I've done it as a 9-5 employee, contractor, subcontractor, technical-cofounding entrepreneur, and to scratch my own itches.
Cofounded two startups as CTO and primary developer. One is already winning, one is about to win any minute now. Countless successful projects as an employee, contractor, subcontractor, open source contributor, consultant, own-itch-scratcher.
