Worked on the keiyoushi/extensions-source repository to deliver a targeted feature update for two Android extensions, MangasBrasuka and MugiwarasOficial. Updated the ad-wall query parameter to align with a new API requirement, ensuring both extensions remained compatible with backend changes. Leveraged Kotlin and Gradle to implement version bumps and update build scripts, supporting a smooth release and deployment process. Addressed minor code quality issues, including a typo correction, to improve maintainability and user-facing messages. Focused on reproducibility in continuous integration, the work emphasized careful release preparation and adherence to best practices in Android development and web scraping workflows.
