Worked on the MaaAssistantArknights repository to enhance system stability and reliability by addressing two critical bugs in game logic. Focused on correcting the Trading Station Group Logic to ensure proper application of group rules, which prevented unintended trading behaviors in the Originium Order Trading Station. Additionally, resolved an issue in the InfrastProcessingTask by modifying the on_run_fails handling, returning true and adding explicit logging to avoid repeated execution and improve observability. Utilized C++ and Java for debugging and root-cause analysis, demonstrating strong skills in bug fixing and task management while prioritizing data integrity and maintainability throughout the development process.
