About me
Every missed call is a lost customer or a lost deal. I build AI voice agents that answer, qualify, and book.
Four voice AI categories:
→ Inbound Voice AI — ai call agent, customer service, inbound automation, missed calls
→ Outbound Voice AI — ai calling, warm outreach, sales automation, re-engagement
→ Appointment Setting — ai appointment setter, sales closer support, calendar booking
→ Custom Voice Agents — Vapi, Retell AI, Synthflow AI, webhook automation, function calling
24/7. No script fatigue. No missed calls. Message me with your call volume.

I came in with a Claude-powered voice agent that was burning through tokens at an unsustainable rate and no idea where the waste was actually coming from.
