I build production AI systems and full-stack applications — not prototypes, not tutorials, real deployed pipelines that handle errors, manage costs, and your team can maintain.
What I've shipped recently: a multi-agent platform searching 96 data sources with LLM batch scoring, 7 adapter types, cron automation, and 11-tab dashboard. A hub-and-spoke web platform generating production-ready sites across news, marketing, government, and education — 24 shared modules, 49 UI components, 2,276 test files. Cross-platform mobile apps with Expo/React Native — 35+ native integrations, App Store ready.
