Most agencies handle SMS, WhatsApp, and voice calls as three separate, disconnected workflows. I'm building the system that makes them one.

An agency serving clients across multiple industries needed a unified way to respond to leads, process documents, and run follow-ups — regardless of which channel a lead came in on. Manual handling meant slow response times and inconsistent quality as they scaled to more clients.

I'm architecting an n8n automation core that connects Twilio (SMS), WhatsApp Business API, and Retell.ai (voice AI) into a single pipeline feeding OpenAI for instant, on-brand lead response and automated document processing — with reusable modules the agency deploys for each new client vertical without rebuilding from scratch.

Result so far: lead response time cut from hours to minutes, with a growing library of white-labeled automation modules the agency reuses across onboarding after onboarding.

This is an active, ongoing engagement — the kind of multi-channel AI automation work I specialize in, combining n8n, Twilio, WhatsApp, voice AI, and OpenAI into systems that scale with the business, not against it.
