Worked on the keiyoushi/extensions-source repository to maintain and enhance Android extension sources, focusing on resilience and compatibility. Addressed the closure of the One Piece TECA site by removing its extension, reducing maintenance overhead. Improved the Softkomik extension by implementing a WebView-based fallback, ensuring session continuity despite frequent API changes. Updated the Ikiru extension’s domain and version code to maintain compatibility with backend updates. Utilized Kotlin and Gradle for development, emphasizing robust error handling and API integration. The work resulted in fewer user-facing failures during API transitions and streamlined future migrations across multiple Android extension sources.
