About this gig
INBOX ME BEFORE PLACING AN ORDER.
Missed calls are lost revenue. I build AI voice agents with Retell AI or Vapi that answer, qualify, book, and follow up on real phone calls, sounding natural and staying on script, so your business never misses a lead.
This is not a static IVR menu. It is a real conversational voice agent that understands intent, pulls answers from your data, and takes action: booking a slot, transferring to a human, or logging the call.
What I can build for you:
- Inbound and outbound voice agents on Retell AI or Vapi
- Call flows for booking, support, sales, and lead qualification
- Integration with your calendar, CRM, and phone system
- Human handoff for calls that need a real person
- Voice agents grounded in your own business data
My stack: Retell AI, Vapi, Python, Twilio, OpenAI and Claude APIs, and CRM integrations.
As a Level 2 seller with 100+ completed projects, I ship reliable, tested voice agents with clean setup and on-time delivery.
Tell me what your calls need to handle and I will design the voice agent that handles it.

FAQ
What's the difference between Retell AI and Vapi, and which do you recommend?
Both are strong voice AI platforms. Vapi tends to offer more flexibility for custom logic and integrations, while Retell AI is often faster to deploy for straightforward call flows. I'll recommend based on your use case and technical needs.
Will the voice agent sound robotic?
No. Modern voice AI on these platforms uses natural-sounding speech with real-time responses, and I tune tone, pacing, and phrasing so it fits your brand rather than reading like a script.
Can it actually book appointments?
Yes. The agent can check your calendar, book a slot, send confirmations, and log the interaction in your CRM, included from the Standard tier up.
Do I need my own accounts for Retell AI, Vapi, or the phone number?
Yes, you'll hold your own platform and telephony accounts so usage and billing stay under your control. I'll guide you through setup and can recommend the right plan for your call volume.
What happens when a caller needs a real person?
The agent detects when a call is beyond its scope and hands off to a human, either by transfer or by flagging the call with full context so your team isn't starting cold.
How do you keep it from mishandling sensitive requests, like a real emergency?
I build in clear escalation rules so certain triggers route straight to a human rather than letting the agent attempt to handle them, and I test these paths before launch.
