Project History
Financial Systems Reconciliation & Revenue Integrity Portfolio
Implemented specialized workflows for SAP S/4HANA and Stripe to ensure 100% payout accuracy and recover lost revenue through automated churn recovery and dispute defense.
Developed and managed specialized financial workflows designed to ensure cash flow integrity for global businesses. My work focused on two primary ecosystems: SAP S/4HANA and the Stripe billing platform.
In the SAP S/4HANA workflow, I managed complex partner reconciliations, resolving commission discrepancies by auditing ledger entries and overseeing sensitive “change of ownership” transitions to maintain historical data integrity. Within the Stripe ecosystem, I specialized in matching payouts to bank deposits and navigating the Stripe Dashboard to defend against chargebacks, effectively protecting client revenue.
Additionally, I used technical churn-recovery strategies by monitoring failed payments and automating follow-up sequences to recapture lost subscription revenue. This role required a unique combination of my bachelor’s degree in IT for system troubleshooting and my professional experience in financial policy negotiation.
