Developed a unified Rncalation extension for the keiyoushi/extensions-source repository by merging two existing scanlation sources, Traducciones Amistosas and KnightNoScanlation, into a single, maintainable extension. Leveraged Kotlin and the Jsoup library to update parsing selectors and implement enhanced filtering logic, ensuring compatibility with the new source structure. Introduced logic to exclude novels from manga results, improving content relevance for users. Addressed pull request feedback and consolidated related extensions to streamline the development workflow. This work demonstrated a strong grasp of Android development, web scraping, and extension architecture, resulting in reduced maintenance overhead and improved reliability across supported sources.
