About this gig
Stop losing calls to voicemail. I build AI voice agents that answer every call, qualify leads, book appointments and hand off to your team, around the clock.
Most voice AI freelancers know prompts. I know telephony. I have 25 plus years running contact centers, hold FCC Voice Service Provider status, and operate STIR SHAKEN compliant calling infrastructure. Your agent will sound natural and connect reliably.
What I deliver
Inbound AI receptionist on Retell AI, Vapi or LiveKit
Call transfer, FAQs, lead capture and calendar booking
n8n workflows for CRM logging, SMS follow up and confirmations
SIP trunking and custom telephony routing
Compliant outbound calling with opt out handling
Call reporting and post launch tuning
How it works
1. You share your scripts, FAQs, calendar and CRM access
2. I build, test with live calls and refine
3. You get full admin access, documentation and a walkthrough
You own every account and workflow. Platform and per minute call costs are billed directly to you, with no markup.
Not sure which package fits. Message me with your call volume and tools, and I will recommend the right setup.

I architect low-latency AI voice agents and production-grade backend automations that eliminate manual work. My builds connect conversational voice layers (Retell AI, Vapi, LiveKit) directly into existing CRMs, relational databases, and enterprise APIs using self-hosted n8n workflows and Cloudflare Workers.
Rather than simple toys, every deployment is engineered for enterprise reality: sub-700ms latency, deterministic data routing, graceful human fallbacks, and normalized PostgreSQL schemas.

FAQ
Which platform do you use: Retell AI, Vapi or LiveKit?
All three. Retell and Vapi get you live fastest. LiveKit suits custom, self-hosted or high-volume builds where you want full control and lower per-minute costs. I recommend one based on your volume, budget and integrations.
Do I need a new phone number?
No. I can forward your existing number to the agent, port it, or set up a new local or toll-free number.
What ongoing costs should I expect?
Platform, telephony and AI usage are billed to you directly at cost, usually per minute. I give you a monthly estimate based on your call volume before we start.
Can the agent transfer calls to my team?
Yes. It can do warm or cold transfers to staff, take messages when nobody is available, and send you a summary of every call.
What do you need from me to start?
Your FAQs or script, business hours, transfer numbers, and admin access to your calendar and CRM. The delivery clock starts once I have these.
Is outbound calling compliant?
I build in opt-out handling and caller ID authentication. You're responsible for having consent to call your contact lists under TCPA, Ofcom or your local rules, and I can explain what applies to you.
