Worked on the jmix-framework/jmix repository to deliver comprehensive Traditional Chinese (Taiwan) localization for Jmix Framework 2.7.x, enabling a native user experience for Taiwan-based developers. Implemented end-to-end zh_TW translations across 37 modules, including both core and addon components, using Java and Gradle to manage properties files and build configuration. Enhanced the build system by introducing new Gradle tasks for packaging and publishing translation artifacts, ensuring seamless integration into distribution workflows. Applied OpenCC s2twp conversion to maintain accurate Taiwan-specific terminology, addressing localization gaps and supporting broader adoption of the framework by reducing friction for international users.
