You will get A Vapi AI caller that qualifies leads and books appointments 24/7
Project details
I will build and deploy a production-ready AI voice calling system that handles inbound and/or outbound calls, qualifies leads, books appointments, and updates your CRM automatically.
What makes my setup different: I don’t just “create an agent”—I deliver a complete workflow that works in real life. Your Vapi voice agent is designed with a clear call flow (greeting → qualification → objection handling → booking/transfer), guardrails, and structured data capture. Every call outcome is logged and routed into GoHighLevel (GHL) (contacts, tags, custom fields, and pipeline stages) using webhooks + Make/Zapier/n8n so nothing is missed.
Use cases I build:
AI receptionist + missed-call text-back
Outbound AI appointment setter (lead list → calls → disposition → follow-up)
After-hours booking + FAQ handling
Call transfers to a human when needed
Deliverables include: agent prompt/scriptwriting, Twilio/number setup (if needed), CRM integration, automated follow-ups (SMS/email), testing, and a handover doc so you can run it confidently.

AI Voice Agent Developer Needed (Retell AI, Vapi, GoHighLevel, Zapier, Make.com Integration Expert)
David did an excellent job building our AI Voice Agent system. He integrated Retell AI with GoHighLevel CRM and set up the necessary workflows using Zapier and Make.com to automate lead qualification and appointment booking.
The voice agent handles inbound and outbound calls smoothly, and all data syncs correctly with our CRM. He also implemented SMS and email follow-ups, API connections, and webhook triggers without any issues.
Communication was clear, deadlines were met, and he was very responsive to adjustments during the project.
If you’re looking for someone experienced in AI voice automation, CRM integration, and workflow automation, David is a solid choice.
Would definitely work with him again.

Job Success
Lagos, Nigeria - 9:05 am local time
I build premium AI voice agent systems that answer inbound calls, qualify leads, route conversations correctly, recover missed calls, and book appointments automatically using Retell AI, Vapi, Twilio, and GoHighLevel.
What I help with:
AI receptionist systems for inbound calls
Missed-call recovery and callback automation
Lead qualification and appointment booking
Call routing for sales, support, and dispatch
CRM updates, pipeline movement, and tagging in GoHighLevel
Webhook, API, and workflow integrations
My focus is on reliable systems that fit real business operations, not demo bots. The goal is to reduce lead loss, improve response speed, and make sure every call is handled professionally.
If you need a voice system built around your sales process, send me your workflow and I’ll map the right setup.
