Kemin Zheng contributed to the SwEnt-Group8/Street-work-app project by enhancing the user profile experience on Android. He implemented a feature that retrieves the user’s profile picture directly from Firebase Authentication, replacing the previous reliance on an external placeholder with a local asset. This approach, using Kotlin and Jetpack Compose, streamlined the image fetch logic, reduced network dependencies, and improved load performance on the profile screen. The update resulted in a more consistent user interface and simplified future maintenance. Kemin’s work focused on code readability and maintainability, with minor refactors and no major bugs reported during the development period.
