Worked on the hydralauncher/hydra repository to deliver comprehensive Portuguese (pt-PT) localization and user experience enhancements, focusing on broadening accessibility for Portuguese-speaking users. Leveraged front end development and i18n skills to implement JSON-based translations across core features such as notifications, library, and game details, while introducing local features like banner management, friend messaging, pinned games, and a voting system. Ensured full pt-PT coverage by addressing missing translations and standardizing terminology throughout the application. All updates were validated and staged for QA, with particular attention to Portugal-specific currency handling and consistent user interface design, improving overall localization quality.
