Nov 1, 2025November 2025 (Let-s-intern/lets-intern-client) – concise monthly summary of feature delivery, bug fixes, business impact, and technical growth. Key features delivered: - User Experience Management: Implemented UX retrieval, filtering, and UI integration with server data; added data transformation utilities to map API values to UI; server-filtered queries kept in sync with UI selections. - Experiences Rendering and Submission Enhancements: Server-driven experience lists rendered dynamically; 3+ experiences required for submission; pre-apply submittedUserExperienceIds and handle edit restrictions via modal; LV1/LV2 classification rendered conditionally. - Attendance API: Added/modified attendance creation API to support attendance tracking workflows. - Query optimization and API request control: Added enabled flag to prevent unnecessary queries and migrated filter requests to GET to reduce server load. - API-driven UI data loading: Refactored UI to fetch data via API rather than external injection, improving reliability and consistency across pages. - Data Typing and UI refinements: Data table typing improvements, alignment adjustments, and cleanup of legacy usage examples. - Multi-filter core capability: Replaced single-filter with multi-filter dropdown for core capabilities to improve UX and accuracy of filtering. - Latest navigation and resume links: Implemented detection for navigating to active B2C’s latest challenge; added resume latest link and a common hook for moving to the latest challenge; migrated navigation state to useRouter. - Career Board ecosystem enhancements: Reorganized career board components into domain-driven folders, added career plan, certificate/document整理 UI, and loading components; extensive UI styling improvements for consistency and mobile responsiveness. - Performance and UX polish: Added loading UX for dashboards, mobile layout fixes, disabled-state styling, and improved pagination behavior to prevent loss of selected items. Major bugs fixed: - URL corrections for career management/experience sections. - Removed duplicate declarations introduced during refactors; addressed regressions via targeted reverts. - Fixed pagination-related disappearance of selected experiences and corrected button enable/disable logic. - Fixed compatibility issues in user experience filtering API and input parameters after API changes; updated pagination and filtering flow to reflect current API contracts. - Resolved data loading bottlenecks and added loading indicators on CareerBoard and Experience sections. Overall impact and accomplishments: - Significantly improved user productivity and confidence in the system by delivering end-to-end UX management, reliable server integration, and robust data loading patterns. The UI now responds faster to user actions with fewer redundant API calls, while critical journeys (experience submission, attendance, and career board workflows) are streamlined and more maintainable. Technologies/skills demonstrated: - React/TypeScript, API integration, RESTful design, and GET-based filtering. - State management with router-based navigation (useRouter) and client-side data shaping. - Performance optimization, loading UX, and responsive/mobile-first styling. - Domain-driven UI refactoring and componentization for career-related features. - Data typing and cleanup to improve maintainability and reduce runtime errors.

Oct 1, 2025In October 2025, delivered reliability, performance, and SEO improvements for lets-intern-client. Implemented a single-flight token refresh mechanism with header optimization to prevent duplicate refresh requests and to avoid sending Authorization headers when tokens are missing, reducing race conditions and unauthorized calls. Refactored data fetching to display B2C challenges immediately via the new useFirstB2CChallenge hook, cutting sequential API requests and speeding up the home and category bars. Added a Naver site verification meta tag in the layout to support search ownership verification. Expanded test coverage for axios interceptors to improve resilience and maintainability.
