Worked on enhancing the TrueNAS Web UI by updating Polish language localization to improve translation accuracy for Polish-speaking users. Focused on refining frontend components and ensuring that internationalization and localization standards were met throughout the interface. The work involved reviewing and updating translation strings within the truenas/webui repository, with careful attention to context and usability for native speakers. By addressing inconsistencies in the Polish translations, the update aimed to reduce localization-related support issues and improve overall user satisfaction. Utilized frontend development skills alongside expertise in i18n and localization processes to deliver a targeted feature that supports broader accessibility goals.
