Yuxin contributed to the AzureAD/microsoft-authentication-library-for-objc repository by modernizing authentication APIs, enhancing sign-in and password reset flows, and improving test reliability across iOS and macOS platforms. Using Objective-C, Swift, and Kotlin, Yuxin refactored legacy interfaces to parameter-based APIs, integrated OTP-based authentication, and implemented end-to-end and unit testing for native sign-in and self-service password reset. The work included stabilizing CI pipelines, addressing macOS-specific bugs, and updating documentation to support release readiness. These efforts reduced integration friction, strengthened security, and improved maintainability, demonstrating a deep understanding of authentication, API design, and cross-platform mobile development best practices.
