About Me

16 years of software development experience, both as first developer at start-ups and as development

team lead.

I've built and shipped half a dozen Rails websites, and have over 5 years of Ruby and Rails

experience.

I ve built three commercial iPhone applications and one iPad app.

83% of my work history has been with tech start-ups. I love working with small, smart, aggressive

companies to build up their software platform and development team.

OpenCola

Team Lead, ColaVision, April 2000 - August 2001

Toronto, ON

VB, Java

I was hired by OpenCola for research and development to explore ways of building on then-nascent

peer-to-peer networks. My team was charging with exploring network efficiencies, protocol

anonymization, and "just trusted enough" PKI, all of which culminated in ColaVision.

ColaVision - Visual Basic. ColaVision was a distributed, p2p media discovery and delivery

system that ran atop the Napster, Scour and Gnutella networks. It debuted at DefCon in Las Vegas in

2000 and was promptly shut down by the lawyers and locked away forever in 2001. That was probably

a good idea.
