Challenge
Before

Open/closed data for hundreds of stores lived scattered across Excel and individual stores, with no way to see the whole picture. Registration was manual with frequent missed updates, escalating operational load and errors.

  • Want to centrally manage store operating data
    Scattered across Excel and stores, hard to grasp
  • Want operating status at a glance
    No monthly overview possible
  • Want to reduce manual closure registration
    Registration errors and missed updates
  • Want to filter quickly across hundreds of stores
    Finding the target store takes time
Solution
After

A React + TypeScript SPA that integrates a monthly calendar (react-big-calendar), store filter and closure-registration form on one screen. Redux Toolkit centralizes the state of every store, and PWA adds offline capability.
