Professional Summary

I am an accounting professional with 7+ years of cross-industry experience spanning audit and control, medical billing, and healthcare operations — a background built with purpose and precision. I have deliberately built my career across two demanding industries: multinational corporate accounting and the highly regulated world of U.S. healthcare billing, delivering the same unwavering standard in both — zero tolerance for error. I consistently maintain accuracy, reduce processing errors, and ensure compliance-driven outputs that businesses can rely on. I bring precision, accountability, and cross-industry fluency to every engagement — and I am ready to bring that same standard to yours.
