About this gig

Give your business a voice that never sleeps - an AI agent that answers calls, books appointments and talks to your customers 24/7.


I build AI voice agents and phone agents with Vapi, Retell AI and Twilio - production-ready, tested on real calls with human transfer built in.


What I build:

  • AI Receptionist - answers inbound calls, handles FAQs, routes callers
  • AI Appointment Setter - books meetings with live calendar sync, sends SMS/WhatsApp confirmations
  • Outbound Calling Agent - lead qualification, follow-ups, ai cold calling campaigns
  • Voice RAG Agent - answers from documents with cited sources(LangChain, vector DB) - no made-up answers
  • Website Voice Widget - voice Q&A embedded on your site or app


Every build includes: natural conversation design, human handoff, CRM logging(HubSpot, Airtable), call summaries, error handling and a clear running-cost estimate before we start-no surprise bills.


Tech: Vapi, Retell AI, Twilio, ElevenLabs, OpenAI, Claude, LangChain, n8n, Pinecone


Message me before ordering - tell me your use case and I'll map the call flow with a cost estimate first.
