At Spread, allocated to Caixa Econômica Federal, I created the app’s new login screen in SwiftUI and Combine and worked on migrating its Home screen from UIKit. I also worked with modular and Clean Architecture, dependency injection, and backend API integrations on banking features.

I created Gym Game, an app built with Swift and UIKit using MVVM-C that has almost 1,000 downloads. At Leal Apps, I proposed XCTest unit testing, taking coverage from 0% to around 60%, and improved a purchase screen’s opening time by two seconds, increasing sales by 15%.
