Hi! I’m Richard Demsyn-Jones. I work at Thumbtack, where I manage applied scientists and engineers in our Marketplace and ML Infra teams.

I write a technical blog, Simplicity is SOTA, on machine learning, engineering, and marketplaces. Check it out!


I am an avid reader of books, papers, articles, newspapers, newsletters — anything, really. See the list below for a sample of the topics I spend my time reading about. I’m always excited to find intellectually curious folks, to share ideas with or collaborate. Don’t be shy about reaching out if you would like to talk or I could be of some help to you.
