I run operations for a US limo booking service and built the software it runs on, including the voice AI that answers the company phone: quotes off live rate logic, checks real availability, books. Eight years carrying the revenue number and building the stack under it: a self-hosted contact-centre replacement, a metrics pipeline the vendor never shipped, browser automation against a portal with no API, now agents in production. Separately built and monetized modalruns.com.

Looking for: AI/agents engineering or technical-operator roles. I was the customer before I was the vendor. I build systems for businesses I understand from the inside.
