In June 2025, the KOIN_WEB_RECODE work focused on mobile-first UX improvements, robust user data modeling, and streamlining authentication-related flows. Key changes include a new isMobile hook for consistent mobile UI decisions and an enhanced UserResponse object (adding id: number) to ensure accurate data representation across devices. A dedicated phone verification hook was introduced for the Find ID flow, encapsulating API calls and state management to simplify maintenance and improve reliability. UI polish was applied to the email input placeholder color for visual consistency, and obsolete signup verification code paths (SCSS styles, components, and hooks) were removed to reduce technical debt. Overall, these changes improve mobile usability, reduce complexity in critical flows, and contribute to a cleaner, more maintainable codebase with measurable user-facing reliability.

April 2025 (BCSDLab/KOIN_WEB_RECODE): Delivered a comprehensive overhaul of the User Authentication System and Login Page, focusing on UX improvements, modular architecture, and security/observability enhancements. Key work included extracting the useLogin hook, introducing a dedicated LoginForm component, adding AdditionalLink and Footer components, and refactoring the LoginPage into modular components and hooks. Mobile responsiveness was improved, and analytics integration plus token handling were incorporated to support secure, trackable login flows. These changes establish a scalable authentication surface and reduce maintenance overhead going forward. Commit highlights include: 6b9cc47e96ba12eee6e1ee167cdc213369eb85b2; 7f3dc2dc8bcd14e96b4c6761b67bde8bc91df6e0; ae4e5c87e949b70476d37b794f86f837b88a1fb9; d20260755aa2b42ca036a560ca1ccd9e3bdffa18; 3964eefb78116b96b10d407c6e6019c6f2d6c76f; 3d23ec51bb7bffba52dcfe6ffe189472e9ddc192; 509daf5bf9adf32a2ecb30bdad72f27160e886c6

For 2025-03, the team explored a mobile onboarding UX enhancement in BCSDLab/KOIN_WEB_RECODE by attempting to introduce a mobile signup progress bar component. The feature was implemented and committed (3b012f13a8601033f5a199d33bb5fecf71091b1d) to indicate current step, title, and overall progress, aiming to improve mobile user guidance during signup. In parallel, the work was reverted later in the period (bf62efad129546faf56c376fb88c596ca5f95329), removing the SCSS and TypeScript files and disabling the progress indicator to maintain alignment with product design and stability. Net effect: no production changes persisted, but the team gained visibility into onboarding flow complexity, validated rollback processes, and captured learnings for future iterations.
