Muhammet Alitasdemir developed a robust manga source integration for the keiyoushi/extensions-source repository, enabling secure retrieval and AES decryption of content from Merlin and Ragnar scans. Leveraging Kotlin and Android development skills, he implemented episode-level pagination and enhanced metadata parsing to improve genre accuracy. His work included integrating initmanga, updating version identifiers, and collaborating with other contributors to address code quality through lint fixes. By focusing on API integration and data parsing, Muhammet expanded content access and improved data reliability, laying a technical foundation for future source extensions. The work demonstrated depth in handling secure data extraction and collaborative development.
