Contributed to the jellyfin/jellyfin-web repository by delivering a complete Slovak localization for the web user interface, enabling Slovak-speaking users to navigate the application in their native language. Focused on front end development and internationalization, the work involved translating interface strings using JSON and integrating the translations through the Weblate platform. This effort enhanced accessibility and laid the groundwork for future language support within the project. No major bug fixes were addressed during this period, with the primary emphasis on localization readiness and seamless collaboration within open-source translation workflows, supporting the broader product localization strategy for Jellyfin Web.
