iOS SOFTWARE ENGINEER

I build iOS payment apps used by millions of Brazilians.

I've been building for iOS since 2017 with Swift, SwiftUI and UIKit, working on some of Brazil's largest financial apps: Itaú, PagBank and, today, Mercado Pago at Mercado Libre. I'm also a Swift instructor at iOS Lab, training the next generation of Apple developers.
