Worked on improving localization quality and frontend consistency for Japanese-speaking users across the OpenBAS and OpenCTI platforms. Focused on identifying and correcting translation errors in Japanese language files, addressing issues with placeholders, terminology, and style to ensure a unified user experience. Applied targeted patches in JSON to standardize translations and reduce translation drift, which helped minimize localization-related support issues and improved daily usability for localized users. Leveraged frontend development skills and expertise in i18n and localization to deliver precise bug fixes, contributing to more maintainable codebases and smoother user interactions in both OpenBAS-Platform/openbas and OpenCTI-Platform/opencti repositories.
