Worked on the streamyfin/streamyfin repository to deliver a Dutch localization enhancement, focusing on updating the nl.json file with new key-value pairs to improve translation accuracy across user interface elements. The approach centered on careful JSON editing and localization best practices, ensuring that Dutch translations aligned closely with the intended UI context. This update addressed potential localization drift and enhanced the maintainability of language assets, laying the foundation for broader internationalization in future releases. The work demonstrated attention to detail in managing localization files and contributed to a more robust multilingual experience, utilizing skills in localization and structured data management.
