TITLE: Building a Demolition Automation Engine: Supabase State Machines, Claude Vision, and VAPI Call Routing for Real Estate Ops
When you're running a demolition company from a vertically integrated real estate empire, manual bid responses become your bottleneck. Load Bearing Demo processes incoming project photos via Gmail webhooks, parses structural drawings with Claude's vision API, calculates market-based demolition pricing against a Houston-indexed matrix, routes approval requests through Telegram, and closes the loop with VAPI outbound calls—all without human intervention until the final sign-off. This article breaks down the full backend architecture: a 10-table Supabase schema with relational integrity, a state machine that tracks VAPI call outcomes across 4-touch sequences, a React dashboard for selective bid approval, and the containerized Railway deployment that keeps it running. Built on open-source infrastructure (Asterisk PBX, self-hosted), this is how you scale labor-intensive field operations when your tech stack is your competitive moat.
