I'm currently a freelance developer who is excited about data analysis, data visualization, and machine learning. I work mostly in Python and JavaScript and occasionally Clojure and Java.

I was previously at Keen IO, where I was on the Web Experience team. My responsibilities included developing and designing user-facing applications on the Keen IO website and Keen IO's billing system. Before that, I worked as a Rails and JavaScript consultant at thoughtbot.

I currently live in Denver, Colorado.

Aside from computers, I enjoy dancing, climbing things, travel, reading about meteorology, biking, exploring mountains, and cooking.
