Customer support agents with natural conversation flow
Retell AI and Vapi integrations connected to your CRM or calendar
Multi-step call flows with live handoff to a human when needed

Why work with me:
⭐ Level 2 seller with a 5.0 rating and 90+ completed orders

FAQ
What can an AI voice agent actually do?
It can answer inbound calls, make outbound calls, qualify leads, book appointments, answer FAQs, and route callers to the right place,. all with natural conversation, not a rigid phone tree. If it needs to, it can hand off to a human seamlessly.
Retell AI or Vapi, which do you recommend?
Both are strong platforms; I'll recommend based on your use case, budget, and any existing systems you want to integrate with. I work with either, so we pick what fits you best.
Can the voice agent connect to my CRM or calendar?
Yes. CRM and calendar/appointment-booking integrations are included from the Standard package up, so the agent can check availability, book slots, and log call outcomes automatically.
Will it sound robotic?
No, that's the main thing I focus on. I tune the voice, pacing, and conversation flow so it sounds natural and on-brand, not like a scripted IVR system.
Do I need my own API accounts (Retell AI, Vapi, OpenAI)?
Yes, you'll set up your own accounts so usage and call costs stay under your billing and control. It takes a few minutes and I'll guide you through it.
Will I own the voice agent and its configuration?
Absolutely. You get full setup documentation and ownership of everything built. It's your system.
Do you provide support after delivery?
Each package includes revisions, and I offer a post-delivery support add-on for tuning and fixes after the agent goes live.
