Worked on the thunderbird/thunderbird-l10n repository, delivering a series of Fluent-based localization migrations across Thunderbird’s UI components over seven months. Focused on moving legacy DTD and properties strings to the Fluent framework using JavaScript and FTL, the work improved internationalization, accessibility, and consistency throughout the application. Enhanced user interface clarity by standardizing terminology, updating search and message retention UIs, and implementing modern pluralization rules. Centralized localization assets to reduce maintenance overhead and enable scalable translation workflows. The approach emphasized incremental, review-friendly commits, ensuring traceability and maintainability while supporting a more robust multilingual user experience across Thunderbird’s front end.
