Welcome! I’m Chris, thanks for visiting my page.
Career
I’m the co-founder of refresh.dev (YC X25) - we help AI Labs train smarter frontier models by providing them with environments for them to run RL with.
Previously, I was a Machine Learning Engineer at Uber for 4 years, where I pioneered many innovations in the company’s feature store ecosystem, allowing ML Engineers to train models that leveraged highly predictive low latency features for ai models used across many problems including fraud detection, home feed ranking, and search.
Interests
ML Systems, Running, National Parks, roller coaster tycoon, and RL.
Education
Grad / Undergrad Computer Science @ University of Illinois in Urbana-Champaign (UIUC) Completed Dec 2020
My graduate work was advised by ex-UIUC Stanford professor Sanmi Koyejo; I built the initial federated learning infrastructure to support privacy preserving computer vision models for hospitals local to the Urbana-Champaign (Paper).
