During November 2024, Kemin Zheng enhanced the user profile experience for the SwEnt-Group8/Street-work-app by delivering a feature that retrieves profile pictures directly from Firebase Authentication, with a local asset as a fallback placeholder. This approach reduced reliance on external resources, improved load performance, and ensured a consistent user interface. Kemin simplified the image fetch logic, making the codebase more maintainable and reducing unnecessary network calls. The work involved Android development using Kotlin and Jetpack Compose, with a focus on Firebase Auth integration. No major bugs were reported, and minor refactors further improved code readability and future extensibility.
