Enterprise System Architecture

Deterministic Multi-Tenant Router & Vector Pipeline

Unlike brittle chatbots, this production engine enforces strict business hours, executes vector knowledge retrieval in sub-2 seconds, dynamically verifies slot availability, and writes completed bookings straight to Google Sheets and team Slack channels.

01 / VOICE TURN-TAKING

Sub-800ms WebRTC Voice Stream

Configured with custom voice-activity detection (VAD), 0.9s speech pauses, and 1.2s digit preservation. Eliminates robotic delays and lets callers speak uninterrupted in natural human cadence.

02 / DUAL-GROUNDED RAG

Zero-Hallucination Vector Search

Whenever a caller asks about pricing, packages, or clinical policies, the engine executes real-time semantic vector retrieval against Pinecone. The assistant only answers using verified business facts.

03 / MULTI-TENANT ROUTER

Deterministic Event Router

An n8n switch engine separates system heartbeats, knowledge queries, availability checks, and booking updates. Automatically enforces operational hours (Mon–Fri, 9 AM–6 PM) and flags conflicts.

04 / CRM SYNCHRONIZATION

Bi-Directional Database Sync

Checks slot capacity dynamically to avoid double-bookings. Supports complete lifecycle actions (Booked ➔ Cancelled ➔ Rescheduled) with instant HTML email confirmations and team Slack alerts.
