SUMMARY
A sharp, results-driven billing professional who actually enjoys digging into payment flows, chasing down
disputes, and squeezing every last percent out of fraud and chargeback metrics. I bring a rare combo to the
table: the analytical rigor of a billing ops specialist, the calm precision of a former medical professional, and
the people-first instincts of a top-tier customer support agent. I thrive in fast-paced international
environments, switch effortlessly between time zones and cultures.
