  Responsibilities & Achievements: Successfully developed the project material management page and data management for the cutter head using React technology stack along with the Material-UI component library. Efficiently managed and retrieved data through Axios and RESTful APIs, ensuring smooth and reliable data flow. Utilized the Koa framework for backend development, optimizing the handling of asynchronous middleware and improving server response time, and combined it with Sequelize ORM for MySQL database management to enhance data management efficiency. Difficulties & Challenges: Encountered page refresh flickering issues, and we resolved the flickering problem related to DOM initialization operations by using useLayoutEffect and understand the source code logic and timing mechanism of effect functions, including useEffect and useLayoutEffect. Managed state using Redux and executed asynchronous requests using redux-thunk middleware. As the project size increases and the number of component codes becomes extensive, the code was refactored and optimized, separating components into a design pattern of logic components and display components. In React, route guards were implemented using components. Optimized the code using memo, useMemo, and useCallback. Extracted common logic with custom hooks and separated repetitive logic using HOC Show less
