HELLO WORLD

My name is Devon Peticolas; I'm an NYC-based software engineer who loves functional programming, programming history, and building environments that foster compelling data science.

I work at Oden Technologies. I often speak at conferences and meetups about data science, engineering, and machine learning. I also teach data science and machine learning for Columbia's Pre-College Program.

In my spare time I ride bikes, play games, and am perfecting my mint chip ice cream recipe.
