What I work on

  • Product engineering: web and native apps from schema to store listing: auth, payments, subscriptions, offline-first data, push, analytics
  • AI systems: LLM features inside products, agent orchestration with human approval gates, MCP tool integrations
  • Backend & data: Postgres/Supabase schemas and row-level security, APIs, webhooks, search, caching, background jobs
  • Healthcare & EMS: software informed by 12 years in EMS: clinical education, exam prep, first-responder networks

Open to select contracts, consulting and technical partnerships.

GitHub streak

Most of my product code lives in private repositories; the stack above is taken from those codebases.
