Lucas Marantes contributed to the jellyfin/jellyfin-web repository by enhancing its internationalization support, specifically focusing on Brazilian Portuguese localization. Over the course of one month, Lucas delivered updated pt_BR translations using JavaScript and the Weblate platform, integrating new UI strings to improve accessibility and usability for Brazilian users. The work streamlined the translation workflow, ensuring that onboarding and daily interactions for PT-BR speakers were more intuitive. While the contribution was limited to a single feature and did not involve bug fixes, it addressed a clear need for broader language support and aligned with ongoing localization efforts within the project.
