Over four months, Jae Hyun Shin developed and enhanced multiple frontend features for the HIUMC/UMC-9th-Web-Study repository, focusing on scalable React applications with TypeScript and Vite. He built core modules such as a to-do list, a movie browser, and a movie search application, integrating APIs and implementing responsive UI components with Tailwind CSS. His work included authentication flows, state management with Context API and Redux, and performance optimizations like throttling hooks for shopping cart interactions. By aligning data models and refining navigation, he established maintainable project structures and improved user experience, demonstrating depth in frontend architecture and API integration.

November 2025 — HIUMC/UMC-9th-Web-Study monthly highlights focused on delivering a solid frontend foundation, UX improvements, API/data consistency, and performance optimizations that translate to faster feature delivery and improved user experience. Key features delivered: (1) Initial Project Setup (React + TypeScript + Vite) with ESLint and base app structure; commits d4cabfeef43cd079e3665bc1149d2e91830d9334 and 42847d695495fd49e37ecf270c83442a16ccfda7. (2) Navigation and Comment UX Enhancements: floating home button, improved sidebar, and paginated/sortable comments; commit 0a2cb9173e921ab9380c0f51350293c0a208c02f. (3) API and Data Model Alignment (Logout, Comment, LP Details): endpoint refactors, data model alignment, and basic project docs; commit ff117405a2c389f7f0a1605a00b464bd3bf25241. (4) Shopping Cart with Throttling Performance: introduced a throttling hook for performance and cart item management; commit 4c6d094b376f001a98dceb2b89ce3ecedeafd425. Major bugs fixed: API surface stabilization through endpoint refactors and data model alignment, reducing API/UI drift and clarifying data contracts; plus onboarding improvements via basic docs. Overall impact and accomplishments: strengthened frontend foundation for Q4, improved user experience with responsive navigation and comment handling, stabilized data contracts across modules, and performance gains in cart interactions. Technologies/skills demonstrated: React, TypeScript, Vite, ESLint, API design/refactor, data modeling, pagination/sorting, and performance optimization via throttling hooks. Business value: faster, more reliable feature delivery; smoother cart experiences; clearer onboarding and maintainable codebase.
