What I'm looking for

I'm looking to grow strategic B2B merchant relationships in fintech or payments, improving payment performance, retention, customer experience, and expansion through cross-functional problem-solving.

At Nuvemshop's Nuvem Pago, I manage strategic B2B merchant accounts, resolving complex payment operations across gateways, settlements, reconciliation, refunds, chargebacks, and antifraud. I generated R$3.3M+ in expansion revenue, the highest BRL expansion volume in the relevant period.

I've also led Customer Success initiatives at AppMax, partnering with Risk, Product, Support, Sales, and Operations to improve approval rates, customer experience, retention, and merchant growth in Brazil's payments ecosystem.
