Worked on CollaboraOnline/online to deliver accessibility-focused localization updates, specifically providing Traditional Chinese (Han) translations to improve the user interface for Han Traditional users. Leveraged front end development skills and internationalization best practices to integrate these translations into the existing localization pipeline, ensuring compatibility with future incremental updates. Utilized HTML and JavaScript to manage translation assets and maintain UI consistency throughout the process. The work was completed using Weblate, with all changes tracked and committed for review. No bugs were fixed during this period, and the translation updates were prepared for quality assurance without introducing regressions or workflow disruptions.
