Experience
Key SAP Projects
At Lekoil in Princeton, New Jersey, I led a full-cycle SAP S/4HANA Greenfield implementation for the finance function, including integrating Trade Promotion Management (TPM), Vendor Invoice Management (VIM), and systems such as SAP Ariba, SAP Concur, and Workday. I designed enterprise-wide financial structures, including company codes, profit center hierarchies, and document splitting logic. I implemented trade promotion financial postings and accrual workflows to support seamless TPM integration and accurate reporting.
For Vistra Inc., I implemented the SAP Revenue Accounting and Reporting (RAR) module in alignment with IFRS 15 and ASC 606. I improved revenue recognition, enhanced compliance across multiple entities, and integrated RAR with the Sales and Distribution (SD) and Financial FI modules to enable complete lifecycle tracking from contract to revenue reporting.
At Archway, I led a banking optimization initiative that reconfigured EBS, Lockbox, and Automatic Payment Program (APP) settings to improve payment processes. By reducing manual tasks and banking fees, I achieved $400,000+ in annual savings. I also built custom reports and automated bank reconciliations across legal entities to enhance efficiency and accuracy.
