During two months contributing to HIUMC/UMC-9th-Web-Study, Jang Min Kyu developed a robust shopping cart experience and a movie search application, focusing on maintainable front-end architecture. He used React, TypeScript, and Vite to deliver features such as dynamic cart management, a music cart variant, and a confirmation modal, while optimizing performance with useCallback and memoized components. State management improvements included refactoring modal logic to Zustand and leveraging useReducer for UI consistency. Jang also established a reusable, strictly typed UI codebase, removed legacy directories to reduce technical debt, and laid the foundation for future API-driven enhancements and streamlined user onboarding.
