What I'm looking for

I’m looking to lead high-volume Accounts Payable—training teams, driving process improvement, and ensuring timely month end/fiscal year end closings with accurate 3-way match, vendor management, and fraud/exception resolution.

I am a dynamic Accounts Payable Leader bringing 20 years of passion and experience in Accounts Payable and Accounting. I deliver proven, targeted process improvement results while keeping month end/fiscal year end closings timely and accurate.

I thrive in environments where I can allocate my skills of training and collaborating with teams to prosper. I lead high volume invoice processing with purchase orders, 3-way match, journals, GL Distributions, accruals, and reconciliations—supported by tools like SAP, Oracle Cloud Fusion, NetSuite, and BILL.com.

In my current role as Manager of Accounts Payable Department (01/2026-present), I manage month end closing and balance budget, and I drive process improvement for organized accounting, including GL Distributions, Journals and Monthly Reclasses. Previously, as an Accounts Payable - Consultant (01/2022-02/2025), I supported team execution, weekly budget forecasting, and specialized processing through BILL.com and NetSuite.

I’ve also built expertise across full cycle AP and risk. As a Senior Accounts Payable Specialist, I coordinated ERP system training, delivered top producer results on 3-way match renewable energy invoices, and researched fraudulent bank transactions as a Fraud Analyst—coordinating wire payments, stop payments, and resolution of account discrepancies.
