PROFILE
Fanchao
Fanchao worked on the session-foundation/session-android repository, focusing on improving group chat reliability and message retention in the Android client. Over two months, Fanchao delivered a feature that enhanced disappearing messages by extending the Recipient data model with fields to accurately represent group participant state, using Kotlin and the Repository Pattern to align UI behavior with backend semantics. Additionally, Fanchao fixed a critical bug affecting New To Session message retention in hidden conversations, ensuring data integrity by safeguarding messages from accidental deletion. The work demonstrated depth in Android development, database management, and unit testing, resulting in more robust and reliable messaging features.
