Worked on the keiyoushi/extensions-source repository to deliver the Dokiraw extension source, focusing on enhancing manga search functionality with genre filters and improved pagination. Applied Kotlin and Android development skills to implement robust API integration and web scraping, addressing user experience issues such as element selection, null-safety, and accurate date handling for weekly ranges. Improved the reliability of ongoing and completed status flags and stabilized search pagination for both Popular and Search results. Additionally, resolved build configuration issues and introduced code quality tooling with Gradle and spotlessApply, resulting in a more maintainable codebase and smoother user interactions throughout the extension.
