Engineered features used by 1,000,000+ users as one of the first seven engineers, including mobile app generation support, improved LLM performance tracking, and a general-use agent for iMessage and Telegram. Delivered improvements to the core agent, which placed first in several UI-focused coding agent benchmarks.

TypeScript, Next.js, React Native, Express, Expo, Electron, Redis, Google Cloud, Puppeteer

Delivered 20+ features as the first engineer, expanding database support and improving the core AI agent pipeline to achieve 30% faster generations, 80% fewer SQL errors, and 30% fewer deployment errors across 5,000+ apps.
