Worked on AzureAD Android libraries, delivering two cross-repository releases that expanded sovereign cloud support and enhanced authentication reliability. In the microsoft-authentication-library-common-for-android repository, implemented sovereign cloud discovery and a broker discovery helper, while addressing an authority check issue. For microsoft-authentication-library-for-android, integrated MSAL 8.3.0 to support Azure France sovereign cloud, updated dependencies, and remediated a Moshi vulnerability to strengthen security. Focused on API development, dependency management, and security vulnerability fixing using Groovy and plaintext. Synchronized release and development branches to maintain a stable codebase, ensuring improved resilience and performance in authentication flows across both repositories.
