Takayama developed core business features for the NUTFes/group-manager-2 repository, focusing on robust workflows for stage management, power applications, and purchase lists. Over four months, he delivered end-to-end UI and data flows using React, TypeScript, and Zod, emphasizing maintainability through component refactoring, custom hooks, and state management with Jotai. He improved data integrity and user experience by centralizing validation, introducing deadline-based editing controls, and separating UI from logic. His work included integrating SWR for efficient data fetching, enhancing error handling, and establishing Storybook-driven UI iteration. The resulting system supports reliable, scalable operations and streamlined feature delivery for the project.

June 2025: End-to-end delivery of the Purchase Lists feature with a robust core system, improved UI iteration via Storybook, and targeted refactors to enhance maintainability. Focused on business value: accurate purchase requests, validated data, and hook-based UI state for a consistent UX across the Purchase Lists workflow.

May 2025 monthly summary for NUTFes/group-manager-2: Delivered a focused Power Application UI/UX enhancements with a unified editing workflow, improving data integrity and user experience. Introduced usePowerDisplay hook to centralize display and editing logic, established editing modes, and prepared for prop-based editing. Implemented onEdit and isEdit props to enable explicit controlled editing from parent components. Refined Power component display state and general state management, and enhanced cancel flows. Added temporary storage for unregistered devices and improved cancellation behavior to prevent data loss. Implemented deadline-based editing restrictions with related property updates to enforce business rules. These changes lay groundwork for scalable editing and robust data integrity, reducing risk of invalid edits and improving operator efficiency.

April 2025: Delivered end-to-end power-management features, data lifecycle capabilities for unregistered data, and foundational maintainability improvements in NUTFes/group-manager-2. The work enables faster, more reliable power-application processing and better data integrity while laying groundwork for scalable feature delivery. Key items include the Power application workflow with stage申請 flow, validation schema, data hooks, and default radio options; and unregistered table data management with registration, retrieval, and deletion. UI/UX enhancements improve clarity and efficiency, including separated labels, a delete button in the FormList, and a clear separation of view and logic. Additional architecture and quality updates include constants/types consolidation, centralized validation messages, CSS refinements, and testing scaffolding with component placement tests.

March 2025 (NUTFes/group-manager-2) delivered a comprehensive Stage management overhaul, fortified form validation, improved data flow, and strengthened maintenance capabilities. Key business outcomes include a more reliable Stage creation workflow, faster data loading with SWR, and streamlined API interactions. Notably, we implemented the Stage component with UI and validation cleanup, integrated react-hook-form and resolvers, and migrated to a numeric Stage option ID with corrected comparisons. We also introduced SWR for data fetching, added API hooks/utilities, organized types and created a fetch-existing-applications hook, and established initial values and update mechanisms for existing data. UI/UX improvements include Stage AccordionMenu, FormContainer replacement, separation of UI and logic, and adoption of jotai for state management. Ongoing code quality efforts included Prettier formatting, error width unification, package cleanup, and renaming hooks/types to isEdit/isExist to align with usage.
