I've done quite a bit of contract work over the years. Some of it under NDA, some of it just closed source work that's no longer publicly available.
I also worked 2 years as the lead programmer on Frokk, a social network startup.
There are a bunch of smaller personal projects that I haven't gotten around to open source yet. Hopefully some day.
