• Proficiency with AI-assisted development tools to speed up iOS work, raise code quality, and improve debugging and testing.
• Experience building authentication and identity features on iOS, including biometric authentication (Face ID, Touch ID), keychain services, secure storage and certificate pinning.
• Experience with modern iOS practices such as MVVM or Clean Architecture, dependency injection, automated testing (XCTest, UI Testing) and CI/CD pipelines for mobile.
