I automate billing and revenue reporting, uncovering discrepancies and improving invoice accuracy.

I've improved billing accuracy and revenue visibility at Enstructure Richardson, Ironclad Environmental Solutions, and Phillips 66. At Enstructure, I automated storage charge calculations, saving approximately five hours weekly, and identified $120K in unbilled container handling charges through billing reconciliations.

At Ironclad Environmental Solutions, I built and maintained a Power BI dashboard tracking revenue and DSO patterns across 30 branches, automated company-wide aging AR reporting, and led monthly financial performance reviews.

At Phillips 66, I supported order-to-cash operations through SQL analysis, SAP testing, Alteryx automation, reconciliations, and invoice process improvements that reduced rejected invoices by 75%. I hold a B.B.A. in Finance with a minor in Accounting.
