Worked on the hedyorg/hedy repository to enhance localization and accessibility for Indonesian users by delivering the initial Indonesian translation of the New Year countdown feature. Utilized YAML for managing translation strings and integrated Weblate to establish a sustainable translation workflow, supporting ongoing and future multilingual development. Focused on improving the internationalization readiness of the user interface, the work addressed both technical and process aspects by documenting translation progress and collaboration patterns. This effort laid the foundation for broader international adoption and streamlined future localization, reducing backlog and enabling faster delivery of localized features through structured translation and workflow management.
