What I'm looking for

I seek a remote role with U.S.-based companies focused on subscription billing, AR optimization, cross-functional collaboration, and opportunities to automate processes and grow professionally.

I am a detail-oriented Billing Specialist with 3+ years of experience managing end-to-end billing operations, accounts receivable, and Stripe integrations for SaaS and e-commerce environments. I have a proven track record in subscription billing, account reconciliation, process automation, and financial reporting while maintaining GAAP compliance.

I collaborate cross-functionally with finance, customer success, and product teams to optimize billing processes, reduce AR fluctuations, and improve month-end efficiency through automated reporting. I bring strong Excel/Google Sheets skills, experience with QuickBooks and NetSuite, and a customer-focused approach to resolving billing issues.
