Worked on internationalizing the Metrolist repository by delivering Portuguese localization for the user interface. Focused on translating UI strings and introducing new translations for weekly and monthly playlist features, using XML to manage string resources. Leveraged Weblate to coordinate and track translation progress, increasing coverage from 29.1% to 33.1% and pushing two translation commits to the codebase. This effort aimed to improve accessibility and clarity for Portuguese-speaking users, laying the groundwork for broader adoption. The work emphasized Android development and mobile localization, with attention to translation workflow alignment and future validation of UI rendering for localized content.
