Worked on the ChuijkYahus/Minecraft-Mod-Language-Package repository to deliver a complete Chinese localization for the Terralith Mod version 1.21.1. Focused on updating and restructuring JSON language files, the work introduced a modular approach to localization, making future updates and integration more efficient. Emphasized maintainability by providing clear commit messages and a coherent change history, which supports knowledge transfer and traceability. Leveraged skills in localization and modding to enhance accessibility for Chinese-speaking players, expanding the mod’s reach. No bugs were documented during this period, reflecting a focused effort on feature delivery and structural improvements rather than reactive maintenance.
