At Getnet (Santander Group), I co-designed and built a white-label payment SDK that lets multiple products and brands integrate payments through one reusable platform. I also built App-to-App communication and deep links for payment flows on Smart POS terminals.
At Serasa, I built a Kotlin checkout that generated $1M+ in revenue and developed screens used by 1M+ daily active users. I’ve shipped OAuth2/OIDC login, encrypted token storage, WebView session handover, and accessibility improvements across core flows.
