My AI voice agents have handled 100,000+ minutes of real client calls โ qualifying leads, booking
appointments, and following up automatically, 24/7.
โญ What clients say:
"The AI voice agent instantly qualifies leads. We focus only on serious prospects now โ way more
appointments booked." โ Real Estate Agency Owner
"He built a workflow we could streamline end-to-end with AI voice automation. Seamless experience." โ SaaS Founder
"Very helpful in getting us in the right direction with AI and how it can work for our business." โ Insurance Company Founder
In 4 years running my own AI voice agent business, I've built and delivered hundreds of these systems across real estate, healthcare, insurance, SaaS, and more.
___
The longer version (if you've got a minute):
Missed calls cost businesses thousands every month. Slow follow-ups lose deals to competitors who respond faster. Manual lead qualification wastes your team's time on prospects who were never serious.
I fix all three โ with AI receptionists, AI cold calling agents, and AI sales reps that work around the clock.
Using Vapi and Retell AI, I design and deploy custom AI voice agents that handle real phone conversations: answering inbound calls, running outbound cold calling campaigns, qualifyingleads, booking appointments directly into your calendar, and triggering post-call workflows in your CRM โ all without a human lifting a finger.
My agents don't sound robotic. They're built with natural conversation flows using ElevenLabs voices, trained on your business data, and integrated directly into your existing tools โ GoHighLevel, HubSpot, Salesforce, or whatever CRM you're running.
โ What I build:
- AI receptionists that never miss an inbound call
- AI cold calling agents for outbound lead generation
- AI sales reps that qualify prospects and book meetings
- Appointment scheduling bots synced to your calendar
- Post-call automation โ CRM updates, tagging, follow-up SMS/email
- Intelligent IVR systems using Twilio and Retell AI
- Live call transfer logic and escalation workflows
โ Industries I work with most:
Real estate & mortgage ยท Healthcare & medical clinics ยท Insurance ยท Home services ยท Roofing ยท Marketing agencies ยท SaaS ยท E-commerce
โ My stack:
Vapi ยท Retell AI ยท ElevenLabs ยท Twilio ยท LiveKit ยท Deepgram ยท Make. com ยท n8n ยท GoHighLevel ยท HubSpot ยท Salesforce ยท OpenAI GPT-4
โ My approach:
I map your call flows, build natural conversation logic, integrate with your CRM and calendar, test thoroughly, and make sure everything runs reliably in production. Clear communication throughout โ and a system that actually works inside your real business operations.
โ New to Upwork. Not new to the work.I'm offering a 30% discount to my first few clients here to build my review base. Same 4 years of experience, same systems, same results โ just a lower rate while I'm getting started on this platform.
And if the system doesn't create real value for your business โ you get every penny back. Zero risk on your end.
If missed calls and slow follow-ups are costing your business โ let's talk.
