About this gig
Never miss a customer call, inquiry, or booking opportunity again.
Unanswered phone calls mean lost revenue. I build custom, human-like AI Voice Agents that handle inbound and outbound phone calls, qualify leads, answer FAQs in real time, and schedule appointments directly into your calendar.
Built On Proven Enterprise Architecture: I developed Desklinean AI voice agent platform engineered for hospitality operations, live call routing, booking tool integration, and call analytics. I bring that exact production setup to your business.
What I Build For You:
- Human-Like Voice Conversations: Natural tone with sub-second latency
- Appointment Booking: Automated scheduling via Google Calendar / Cal.com / CRM
- Lead Qualification: Ask custom screening questions and route call data
- Platform Support: Twilio, Vapi, Retell AI, Bland AI, Python, Webhooks
- Full Handoff: Complete prompt logic, API connections, and setup guide
Please send me a message before ordering with your call workflow and target phone stack!
