Worked on the wikimedia/apps-android-wikipedia repository to enhance the startup experience by addressing a visual issue affecting dark mode users. Focused on eliminating the disruptive white flash during app launch, the developer introduced a theme-aware splash screen background by adding a new color resource and configuring the android:windowSplashScreenBackground attribute. This approach ensured a seamless and consistent appearance across both light and dark themes, improving perceived performance and user trust. The work involved Android development and UI/UX design, utilizing XML for resource management. The contribution was precise and collaborative, with clear commit hygiene and traceability throughout the bug-fixing process.
