Here are some of the things I've worked on over the years, some at work, some for fun. They are in no particular order. My level of involvement varied from project to project.
I first learned how to make a web site while working at Media@Work, a small start-up started by my friend Craig Homenko. As I recall, the job interview went something like this:
Craig: Come work for me. I can't pay you much, but then again you don't know anything.
Me: Okay, sounds good.
I had just left graduate school and was delivering pizza and playing ultimate frisbee and not much else. This was much more interesting than delivering pizza. It ended up being a great learning experience with a fun, hard-working crew. I left for reasons which are not entirely clear to me any more. I think the root cause was my bitterness at being forced to wear a suit and tie to work.
