Joe Van Dyk

I'm CTO at Crowd Cow, an online marketplace for meat and seafood. I joined in 2017 as the first engineer and have been there ever since.

Before Crowd Cow I was CTO at Tanga for eight years. Before that I wrote embedded software at Boeing. Most of my work, then and now, has been some flavor of e-commerce: figuring out what people want and making it easy to buy.

I live in Seattle.
