I do computer stuff, and sometimes people pay me to do computer stuff. You could pay me to do computer stuff, if you wanted to.

From 2016-2020 I worked at Jane Street Capital, a proprietary trading firm in New York City. I wrote a lot of OCaml, and worked on some very interesting high-performance systems.

From 2015-2016 I briefly did R&D stuff at Warby Parker. Mostly iOS, OpenCV, and Python.

Before that, I worked at Trello. I used to work at Fog Creek Software, but then we split into separate companies. For a few years I worked on the iOS app, but I also did a lot of work on the web client.

I was an intern at Fog Creek in the summer of 2011, and started there full time in 2012. I left near the end of 2015.

From 2009-2011 I worked as an intern doing “data science” at RW3 Technologies. Mostly C# and SQL. And Windows Forms. Remember Windows Forms? It was a really long time ago.

I have a BS in Computer Science from the University of Texas at Austin. Which is to say: I know some Java.

I like learning different programming languages. I used to spend a lot of my spare time designing languages, but then I started writing Haskell, and it kinda just clicked with me.

I’m afraid of bodies of water so deep that you can’t see the bottom of them and of being forgotten after I die.

I grew up in Austin, spent much of my adult life in Brooklyn, but now I live in Los Angeles.
