Challenge

Paper-based picking and disconnected desktops caused slow fulfillment, frequent SKU errors, and long training time for new staff.

Solution

A cross‑platform Flutter app for rugged devices with BLE scanning, ESC/POS printing, and offline sync. We built a robust device connection manager and scan buffer to handle rapid-fire input.

Implementation Highlights

  • BLE pairing + reconnection management with device battery telemetry
  • HID‑mode scan buffer + haptic/audio confirmation
  • Thermal print queue with templated label rendering
  • Offline sync with conflict resolution
