Worked on the kufu/tamatebako repository to deliver robust internationalization and localization features for a React-based frontend. Over five months, introduced custom React hooks such as useIntl and useNextIntl to streamline type-safe localization in UI components, and enhanced server-side locale resolution for consistent multilingual support. Implemented and documented ESLint rules in TypeScript and JavaScript to enforce i18n compliance, reducing untranslated UI risks and improving code quality. Strengthened type safety by clarifying return types in i18n utilities, and expanded documentation to support onboarding and usage. The work emphasized maintainable, testable internationalization practices aligned with modern frontend development standards.

Nov 1, 2025November 2025: Delivered localization readiness enhancement in kufu/tamatebako by adding an ESLint rule to enforce i18n text usage. The rule require-i18n-text is configured at warn, providing early visibility for localization gaps and enabling team QA to catch missing translations during development. This establishes a baseline for i18n compliance and sets the stage for CI-based localization validation.
