Worked on the UNIkeEN/SJMCL repository to enhance the user interface for French-speaking users by addressing localization issues and improving UI clarity. Focused on internationalization using JavaScript, the work involved correcting French locale translations and refining how text rendered across core screens. This included validating changes to prevent text truncation and misalignment, ensuring that French translations displayed accurately and consistently throughout the application. The approach emphasized careful review of UI components and targeted bug fixes rather than new feature development, resulting in a more accessible and user-friendly experience for French users. The work demonstrated attention to detail in localization quality.
