Worked on the YunaiV/ruoyi-vue-pro repository, delivering a structural refactor within the yudao-common module to enhance the organization of core data structures. Focused on backend development using Java, the work involved reorganizing the property order of the CommonResult and PageResult classes to improve readability and consistency across the API layer. This refactoring aligned the data structures with conventional display logic, making them easier for developers to integrate and maintain. The approach emphasized code maintainability and reduced cognitive load for future contributors, demonstrating a methodical application of refactoring skills and a strong understanding of backend architecture and Java development principles.
