Billing Specialist at RAEL who built a triage engine that cut invoice review from a work-week to under an hour.

At RAEL, I handled end-to-end billing for a US fire-protection services company. I processed and reviewed invoices, traced discrepancies to their root causes, and kept accounts accurate against billing deadlines.

I built a billing triage engine, dashboard, and read-only review agent inside UtilizeCore. The tool reduced a cycle of manual invoice triage from about a full work-week to under an hour of human review.

Before RAEL, I supported US customers at The Office Gurus, Blackhawk Customer Support, and Teleperformance (AT&T account). I handled billing and order questions, disputed transactions, product inquiries, and first-line technical troubleshooting across phone, email, and chat.

I also wrote billing process manuals from scratch and standardized how invoices were reviewed and routed. I use AI tools in my daily work to move faster and catch errors earlier.
