AI Behavior @ Brex

Prompts, Evals, and Character Design (aka Agent Wrangling)

I define what “good” looks like for AI agents and build the systems that enforce it. At Brex, I design prompts, evaluations, and agent behavror, including constitutional scorers, golden datasets, and pass/fail criteria that catch regressions before anything ships

Five years of fintech content design turned out to be excellent training for this. Writing for clarity, compliance, and concision translates directly to writing rules machines actually follow.
