À propos de ce service
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.

FAQ
What are the running costs after delivery?
Voice agents have per-minute costs(Vapi/Retell, telephony and AI model usage) - typically 0.1-0.2 per call minute depending on setup. Before we start, I'll estimate your monthly cost based on expected call volume and I optimize the stack to keep it low. No surprises.
Do I need my own phone number? Can you set it up?
Yes, I handle it. I set up a Twilio number in your country(or port your existing business number where supported) and connect it to the agent. You keep full ownership of the number and all accounts.
Which languages and accents does the voice agent support?
English works best and the agent also supports 30+ languages including Spanish, German, French, Arabic and Hindi through providers like ElevenLabs. Tell me your target language and I'll confirm quality with a test call before you order.
