Worked on two repositories over a two-month period, focusing on game development and localization using XML for string management. In the DanTheMan827/bsqmods repository, addressed technical debt by removing deprecated HeartBeatQuest release files and directories, streamlining the codebase to improve maintainability and facilitate future development. Later, contributed to TeamREPENTOGON/REPENTOGON by implementing Chinese localization support, adding translations to the string table and organizing keys to support future regional expansions. Ensured that all changes maintained build stability and integrated smoothly with existing workflows, demonstrating a methodical approach to repository hygiene and internationalization without introducing regressions or new bugs.
