Worked on the ankidroid/Anki-Android repository, focusing on improving code quality rather than adding new features. Addressed a bug by removing redundant references and resolving Android Studio warnings in the IntroductionSlide and BundleUtilsTest components. This cleanup enhanced code readability and maintainability, reducing IDE noise and minimizing the risk of regressions from outdated references. The approach emphasized careful refactoring and attention to detail, making future code reviews and onboarding smoother. Utilized Kotlin for Android development and applied unit testing practices to ensure stability. The work contributed to a healthier codebase, supporting easier continuous integration and long-term project sustainability.
