The challenge

TrackFlow had no real-time visibility into shipments. Status updates were typed in by hand, and 'where is my order' calls dominated support.

Our approach

We built an IoT-integrated tracking dashboard with WebSocket-driven updates, plus a Flutter driver app with offline-first sync and route optimization.
