Worked on the mostafaalagamy/Metrolist repository to deliver comprehensive Spanish localization across the entire Android application, including UI elements, Discord integration, and AI-related features. Focused on internationalization and accessibility, the project achieved 100% translation coverage for 619 strings using XML and the Weblate platform. The approach established a robust localization workflow, ensuring that future language additions can be managed efficiently. No bug fixes were reported during this period, as the primary emphasis was on expanding language support and improving usability for Spanish-speaking users. This work laid the foundation for broader multilingual support and enhanced user experience in Metrolist.
