Worked on the stremio/stremio-web repository to enhance both localization and user interface quality over a two-month period. Delivered a localization-ready User Authentication System by replacing hardcoded error messages with translation function calls, enabling dynamic multilingual support for login and signup flows. Improved display consistency by correcting language name capitalization in JSON configuration, and refined the settings page UI with label wrapping, multiline titles, and responsive section widths using CSS and React. These changes established a foundation for broader internationalization, improved readability across devices and locales, and ensured maintainable, incremental code improvements aligned with future localization and UI goals.
