Role and contributions
I joined XP Inc as an iOS developer on the security team, where I was responsible for key mobile security features, including facial biometrics, anti-fraud mechanisms, login protocols, and fingerprint authentication. Over the years, I contributed to the development of the latest version of multi-factor authentication (MFA) management. I played a pivotal role in integrating these security features with various product teams, leading numerous integration efforts, creating comprehensive documentation, and coordinating with other teams to ensure seamless implementation.
To achieve this, I worked with architectures such as VIPER and Clean Architecture, using Swift as the primary programming language. Our projects adhered to rigorous test coverage standards, utilizing the XCTest framework to ensure robust and reliable code.
These security features facilitated easy integration for product teams, who previously had to integrate with each MFA individually before the creation of the anti-fraud MFA manager. This development enabled us to introduce new functionalities for clients, such as allowing changes to registration data in the logged-out area with facial biometric authentication.
Later, we migrated all these security features from native mobile to Flutter. I played an essential role in this process by leveraging my knowledge of the native flow to develop new and improved security features in Flutter.
