What I'm looking for

I seek a detail-oriented accounting role focused on high-volume AP/AR, reconciliations, system improvements, strong controls, and professional growth.

I am an experienced staff accountant with a strong background in accounts payable, reconciliations, payroll, and financial controls gained across technology and public-sector organizations. I consistently process high-volume invoices and payments, implement systems, and train colleagues to improve accounting workflows.

At Maplebear and Postmates I handled large invoice volumes through Coupa, Oracle, and NetSuite, managed GL month-end reconciliations for international subsidiaries, and supported payroll and compliance activities. I have hands-on experience with system migrations and accounting implementations, and I ensure adherence to SOX and municipal controls.

I bring expertise in AP/AR, vendor onboarding, lease and vendor portfolio administration, and reporting for federal and state tax requirements. I am detail-oriented, process-driven, and focused on delivering accurate, timely financial operations that support business objectives.
