David Angel

I build AI-powered operations software for US school districts, from Lima.

Currently: leading a 5-engineer team on the platform that runs tutoring operations for 51 schools — matching, scheduling, attendance, billing.

angelstack — my Claude Code stack. Guardrails first, because the AI always says "looks good to me."

  • Stack: TypeScript · Next.js · NestJS · PostgreSQL · AWS
  • Writing about AI product engineering at davidangel.dev
  • 📍 Lima, Peru (UTC-5, same as US Central)

    Guardrails that stop AI-written code from shipping production bugs. Four Claude Code guards — timezone safety, money math, tenant isolation, migration safety — each from a bug that actually shipped.
