About this gig

I will build a powerful AI cold calling agent that helps your business automate calls, qualify leads, and book appointments without human effort.


Using advanced tools like Retell AI, Vapi AI, n8n automation, and GoHighLevel, I will create a fully functional AI voice system that can handle inbound and outbound calls, respond naturally, and integrate directly with your CRM.


This AI system can:


  • Make cold calls and follow ups automatically
  • Book appointments directly into your calendar
  • Handle customer support and inquiries
  • Sync leads into your CRM system
  • Run 24/7 without breaks or delays


Whether you need an AI receptionist, AI sales agent, or voice automation system, I will customize it to match your business needs.


Tools I use:


Vapi AI, Retell AI, n8n, GoHighLevel, Voice AI, CRM APIs, and workflow automation systems.


Lets build a smart AI system that saves time, increases conversions, and grows your business.
