Building a Multi-Agent Valet Trash Command Center: Supabase Edge Functions, VAPI, and Postgres at Scale

OPENING PARAGRAPH:

We built a production command center for Quiet Hours Valet handling 8 concurrent AI voice agents, 5 frontend pages, and 8 discrete automation workflows—all orchestrated through Supabase Edge Functions triggering VAPI webhooks and a normalized 8-table Postgres schema. This technical deep-dive covers the architecture decisions behind a vertically integrated waste services operation running on self-hosted infrastructure, how we structured real-time voice agent coordination through serverless functions, database indexing strategies for high-frequency webhook ingestion, and the deployment pipeline we use to ship updates to Vercel without disrupting live voice calls. If you're building multi-agent systems with Asterisk PBX, VAPI, or need Postgres + Supabase for voice automation at scale, this is the reference architecture.
