During May 2025, this developer expanded the parsing capabilities of KotatsuApp by building a new ReadOnePiece manga source parser within the kotatsu-parsers repository. They focused on backend development and API integration, implementing logic in Kotlin to fetch manga lists, details, and page URLs directly from ReadOnePiece. Their work enabled seamless end-to-end data flow, integrating the new parser with the existing manga loading system to provide users with broader content access. The project required web scraping techniques to reliably extract and structure data, demonstrating a focused approach to feature delivery and a solid understanding of integrating new sources into established systems.
