I work at MailChimp as a software engineer.

I enjoy making things that make it easier for other people to make things. I love complicated systems whether those systems are organic or algorithmic.

I live in Boulder, CO. I enjoy hanging out with my wife and daughter, riding bikes, fishing and photography.


Sometimes I write about writing code or making things. Here are some highlights.

I Don't Know: an article about the "I don't know" moment in interviewing.

Lowering the Bar: potatoes and bias.


After almost 30 years, I'm still mesmerized by Conway's Game of Life, which I talked about during an Ignite at Etsy.

I'm very interested in the process of and art of interviewing, especially technical interviewing. I talked about it shortly after I left Google and at Velocity NYC in 2018.
