Experience

Still in Love

Palo Alto, CA

AI Product Builder

Co-founded an AI product studio, building with ex-Googlers and Stanford OVAL. Runs agentic development across 12 models tiered by capability and risk; keeps development sandboxed from production and gates releases on shadow traffic, daily evals, and human-approved rollouts.

YeahRotten Tomatoes for YouTube reviews (running shoes as a proof of concept)
  • Rejected an 86× cost cut to preserve trust: deterministic-rubric evals showed 45% fewer verified claims per video (11.9 → 6.6) at $0.005 vs. $0.43 per inference run; kept the higher-cost path and set a risk-tiered model policy with daily yield evals.
  • Defined the product around a 30-second decision: distilled 4,516 review videos into 26,056 source-linked claims across 3,442 SKUs, so a buyer gets a buy, skip, or consider verdict at a glance.
HalftimeCollege planning for students and families
  • Conducted 15 weeks of user research with Palo Alto students and parents on college-application anxiety; shaped the product around preserving students' own voices amid AI essay generation.
