Worked on Dutch language translation updates for the th-ch/youtube-music repository, focusing on enhancing accessibility for Dutch-speaking users. Leveraged i18n and localization skills to increase Dutch localization coverage to 98.4 percent, updating 456 out of 463 strings through a Weblate-based translation workflow. Utilized JSON for translation data management and integrated changes via a Git-based process, ensuring future updates can be applied efficiently. This work prepared the application for full Dutch localization and supported expansion into NL markets. The approach demonstrated effective use of translation platforms and cross-functional collaboration, laying groundwork for smoother localization cycles and improved user experience.
