Automation systems

Business automation, engineered for production.

Beyond web development, I build production-grade business automation systems using n8n — handling real payments, AI conversations, and multi-tenant architecture.

AI Voice Receptionist

An AI phone receptionist that answers real incoming calls, holds a natural spoken conversation via Twilio speech-to-text/text-to-speech, checks live Google Calendar availability, and books appointments autonomously — using Groq's tool-calling API with hand-rolled Twilio webhook signature verification (HMAC-SHA1) for security.

  • n8n
  • Twilio Voice
  • Groq
  • Google Calendar

WhatsApp AI Business Assistant (RAG)

A WhatsApp support bot that answers customer questions using Retrieval-Augmented Generation — retrieving answers only from a business's real FAQ knowledge base (via Pinecone vector search) so it never hallucinates prices or policies, with two-way messaging via Meta's WhatsApp Cloud API.

  • n8n
  • Pinecone
  • Gemini Embeddings
  • Groq
  • Meta WhatsApp API

Multi-Tenant Booking SaaS

A true multi-tenant appointment booking system — one workflow serves unlimited businesses, resolving each request to the correct tenant's calendar and data via API key lookup before any booking logic runs, with per-tenant WhatsApp reminders and isolated data access.

  • n8n
  • Google Calendar
  • Google Sheets
  • Twilio WhatsApp
