What I'm looking for

I seek a finance/billing role in a collaborative SSC or remote team where I can optimize billing processes, improve AR performance, and support month-end close.

I am a bilingual finance specialist with 5+ years in Shared Service Center environments, focused on high-volume invoice preparation, review, and collections. I have improved AR portfolio performance from 80% to 95% current in under three months and consistently identify process improvements to increase billing efficiency and data integrity.

I am proficient with Oracle, HighRadius, Xero, Pskloud, COUPA, Advanced Excel and ERP billing workflows, and I serve as an effective liaison between SSC teams, field operations, and account management to resolve billing discrepancies and support month-end close requirements.
