Cameron Pfiffer is a software engineer and financial economist whose public work spans persistent AI systems, probabilistic programming, and technical education. He works at Letta on infrastructure and developer-facing systems for stateful AI agents.

Cameron earned a PhD in finance from the University of Oregon and later worked as a postdoctoral researcher at Stanford Graduate School of Business. His economics research has included Bayesian statistics, industrial organization, asset pricing, and market microstructure.

He has contributed to Turing.jl, an open-source probabilistic programming system written in Julia. His other public work includes AI agent infrastructure, technical writing, AT Protocol projects, and tools for persistent machine memory.

Before his academic and software work, Cameron worked as an alpaca rancher and for Cirque du Soleil.
