Hey, I'm Ethan.

I'm a principal software engineer at Cars Commerce with twenty years of experience building software. I care about performance, observability, and shipping things that people find useful.

I'm currently writing a book on instrumenting Elixir applications. Before that, I started ChicagoDB and Papers We Love Chicago, hosted a podcast, and built a bunch of things that taught me a lot.

Off the clock I'm a dad to two boys, an avid cook, and a BJJ white belt. I enjoy coffee too much, have a thing for stationery and well-made objects, and was once 2017's 136,784th World's Fittest Man. I'll make you watch The Bear and The West Wing if you let me.
