You've made it.

Hi! I'm Sam.

I'm a machine learning researcher working in the field of ML explanations and deep reinforcement learning. I've spent most of my career working on large-scale streaming systems for companies like Twitter and Stripe. I'm currently most interested in the problem of how to present research results in interactive ways that make results intuitive and visual; the relevant phrase is, "Kill the PDF".

I'm most well known in the software world as the author of Summingbird and Algebird, and as the maintainer of Cascalog. I have a secret identity as a mountain athlete, and write race reports from time to time.

I write a blog at this site. Head over to the index to see the latest posts, or subscribe to my newsletter to get a heads up when I post something new.

Here are a few sequences of posts that you might find interesting. If you do find anything valuable, please consider supporting my work on Patreon.
