Building a Multi-Agent Voice Command Center: Load Bearing Empire's QHV Architecture with VAPI, Supabase Edge Functions, and Aste

OPENING:

We built a production voice command center handling 8 concurrent AI agents across valet, real estate, and demolition operations—all coordinated through a single Supabase backend. This article breaks down the technical architecture: how we structured VAPI webhook integrations in Supabase Edge Functions, designed an 8-table Postgres schema to track agent states and automation scenarios, and deployed a 5-page frontend on Vercel that manages everything from voice routing to task automation. If you're scaling voice AI beyond chatbots into operational infrastructure, this is the stack breakdown you need.
