Product engineer with five years of production React and TypeScript at federal scale, plus three years building the ASU Mobile App on React Native and AWS as full-time ASU staff. Day-to-day AI work centers on agent loops, MCP server design, tool use, eval harnesses, prompt caching, Vercel Workflows, and the streaming-UI nuance that makes structured model output feel intentional. AI-augmented daily on Claude Code and VS Code Copilot. BA in cultural anthropology trained me to ask really good questions by reading the gap between what users actually do and what the spec describes.

  1. Open-source and personal projects

    Product Engineer · Applied AI

    2026 – Present

    Public, MIT-licensed

    • Shipped a public CSV agent that picks the right kind of answer (chart, stat card, table, or list) and renders it in the browser. Streams a typed JSON contract from the Vercel AI SDK through the AI Gateway. The live eval scoreboard runs 12 labeled cases against the model on demand and shows per-case accuracy and dollar cost. Zero backend; DuckDB-WASM queries the CSV locally.

    • Shipped a React library on npm (`npm install streamfield`) that fixes the flicker when an AI model streams a structured response. Tablesalt is the first production consumer. Built in TypeScript, shipped with type definitions, MIT licensed. Live playground deployed to Vercel.
