SF Bay Area / NYC$130-175/hr$260-350K
AI/LLM Specialist$125-200/hr$250-400K

Rationale: This project requires specialized skills across multiple premium domains:

  • Next.js 16 + TypeScript (frontend)
  • Mastra AI framework (novel, cutting-edge)
  • LLM orchestration (OpenAI integration)
  • OAuth complexity (5+ Google scopes)
  • Real-time messaging (iMessage bridge)
  • Production infrastructure (Inngest, Turso, Supabase)
