During a two-month period, D. Iwowi focused on expanding Belarusian language support across the Jellyfin and Jellyfin Android TV repositories. They delivered end-to-end localization by integrating Weblate-driven translations, using JavaScript, JSON, and XML to ensure seamless language coverage. Their work established a scalable localization workflow, increasing Belarusian translation coverage to 100% in Jellyfin Android TV and enhancing accessibility for Belarusian-speaking users. By maintaining translation traceability and collaborating across repositories, D. Iwowi improved internationalization readiness for future deployments. The technical approach emphasized open source contribution, localization, and translation, addressing both business and user accessibility needs without introducing new bugs.
