Worked on the surveyjs/survey-analytics repository to enhance the Dutch user experience by correcting localization issues in the analytics UI. Focused on improving the accuracy of Dutch translations for grouping, column visibility, chart types, and download options, addressing a specific bug reported in issue #516. Applied internationalization and localization skills to update UI strings using TypeScript, ensuring that Dutch-speaking users encounter clearer and more reliable interface labels. Emphasized localization quality assurance and commit traceability to support ongoing maintenance. The work resulted in reduced translation-related confusion and a more accessible analytics interface for Dutch users, though no new features were introduced.
