Worked on the KotatsuApp/kotatsu-parsers repository to enhance manga source reliability and expand content coverage. Addressed stability issues by fixing domain resolution for YuriLab and ReadManhua (Resetscans) manga parsers, restoring consistent access to content. Introduced a new parser for the AtsuMoe source, extending the existing KeyoappParser to support additional manga domains and updating summary counts to reflect the expanded data set. Focused on backend development and API integration, utilizing Kotlin and YAML to implement parser logic and configuration updates. The work improved both the robustness of source access and the accuracy of analytics within the parser infrastructure.
