Worked on the GetStream/stream-chat-android repository to enhance the stability of attachment rendering within the Android chat UI. Addressed a bug in the ChannelMediaAttachmentsGrid by ensuring each attachment in the LazyGrid component was uniquely identified, which resolved rendering glitches during attachment sharing. Improved the reliability of automated tests by updating test data, resulting in more deterministic and repeatable outcomes for the attachment-sharing feature. Utilized Kotlin for both UI development and test improvements, focusing on robust Android development practices. The work contributed to more stable releases by reducing UI inconsistencies and increasing confidence in continuous integration and testing processes.
