What I'm looking for

I’m looking for a finance/operations role in an international environment where I can improve daily processes, lead supplier and customer operations, and ensure compliance through strong analytical work—open to remote EMEA.

I bring 10+ years of finance and operations experience across banking, tech, and insurance multinationals. I’m known for a strong analytical mindset and for solving operational issues by coordinating across teams, ensuring compliance, and improving day-to-day processes.

In recent roles, I’ve led recovery operations and handled regulatory compliance through payment oversight, accounting discrepancy resolution, and management of institutional and legal requirements (including garnishment processing and official documentation). I’ve also managed accounts payable for a multi-country supplier portfolio, processed high volumes of invoices and reconciliations, supported month-end closing, and driven continuous process improvements using tools like SAP, BlackLine, and Esker.
