Worked on the jellyfin/jellyfin-androidtv repository to expand localization and enhance playback user experience, focusing on accessibility for Spanish-speaking users. Delivered a complete Spanish localization by translating 630 strings using XML and integrated the process with Weblate to streamline ongoing translation efforts. Introduced new playback information strings, providing users with more detailed status and options within the Android TV interface. Emphasized internationalization and accessibility improvements, laying groundwork for future locale support. The work demonstrated proficiency in Android development, i18n, and localization, addressing the needs of a broader user base and improving the overall usability of the application for non-English speakers.
