MVP warehouse system for order pickers

Task: Development of the Frontend part (PWA) for a warehouse order picking system within 1 week.
What has been done:
• Equipment integration: Configured operation with a Bluetooth scanner (HID) with focus control (input without calling the on-screen keyboard).
• Selection logic: Step-by-step interface "Cell - Product - Quantity" with duplicate protection (debounce 1.5s).
• UX signals: Implemented haptic feedback for success and sound notifications for errors.
• Fault tolerance: Timeout handling (5s) and loss of connection states for operation in warehouse conditions.
Result: Fully functional MVP, tested on Android terminals with ring scanners.
Key skills: React/Vue, PWA, Hardware Integration, UI/UX for Android.
