Over three months, Jang Min Kyu developed and maintained the HIUMC/UMC-9th-Web-Study repository, delivering a React-based single-page application with robust user authentication and dynamic movie data features. He used TypeScript, Tailwind CSS, and Vite to scaffold a modern frontend, implementing reusable components, responsive navigation, and secure onboarding flows. His work included API integration with Axios, custom hooks for data fetching, and careful state management using React Context. By refactoring folder structures, improving code documentation, and addressing authentication timing bugs, Jang ensured maintainable, scalable code that supports efficient user experiences and lays a solid foundation for future feature development.
