I build software systems that learn from use.

Right now my main focus is Bountiful Garden, a neighborhood harvest-sharing network that turns backyard abundance into real community. I'm also building OpenClawBrain, a memory layer for long-running AI agents. Pelican is a private research system for autonomous options trading.

Instacart

San Francisco

Machine Learning Engineer

At Instacart I build production ML systems that make real-time decisions at scale across inventory, promotions, and ads. Before that I did a PhD in economics at UCLA, where I spent years thinking about incentives, learning, and dynamic systems.

  • Built and maintain the batch and real-time inventory-availability platform — production modeling, threshold calibration, and predictions across millions of SKUs.
  • Built automated bidding and auctioneer systems for the Ads platform, allocating spend in real time across a live auction.
  • PhD Economics — UCLA, 2014–2020
  • BA Statistics & Economics — UC Berkeley, 2007–2011

I'm especially interested in conversations about agent infrastructure, applied ML systems, and local-first product design.
