About
Hi, I’m Felipe César Graciano da Mata, a Senior iOS Engineer focused on building high-performance educational apps. I specialize in Swift, UIKit, SwiftUI, and MVVM, and I’ve led large refactoring efforts to improve architecture, maintainability, and loading speed. I thrive in collaborative environments and enjoy turning complex problems into robust, user-friendly solutions.
I thrive in Agile, cross-functional teams and value clean code, robust testing, and user-focused features. In my current role at Afya Holding, I improved stability with Crashlytics-driven debugging and achieved a 99.8% crash-free session rate, while driving architecture improvements that cut loading times by 70%.
