Dhanvantari is an end-to-end ambulance response ecosystem built as a connected suite: a Flutter user app for emergency requests, a Flutter rider app for ambulance teams, a React web dashboard for operations, a Node/Bun backend for dispatch and coordination, and GNSS/NavIC hardware for real-time vehicle telemetry. The system is designed to reduce response time and improve ambulance-hospital coordination through live tracking and centralized decision support.

The problem
Note · 01Emergency response in Chhattisgarh relied on phone calls to a central number, manual dispatcher decisions, and no real-time visibility into ambulance locations. Response times were unpredictable, ambulances were often dispatched from far away while closer ones sat idle, and hospitals had no advance notice of incoming patients.
The approach
Note · 02Implemented a multi-surface architecture where each role uses a dedicated client: patients request support through the user app, riders manage trip lifecycle in the rider app, and administrators monitor operations in the web client. The backend handles session creation, dispatch workflows, tracking streams, and hospital coordination APIs. GNSS/NavIC hardware integration enables reliable field telemetry so assignment and ETA logic can run on near-live coordinates.
How it was built
Milestones from concept through delivery.
UserMobile, RiderApp, WebClient, Server, and GNSS/NavIC hardware integration.
Built the user
Built the rider
Developed the React + Vite web client for dispatcher and operations teams to monitor fleet state and requests.
Implemented backend services (Node/Bun) for API orchestration, session flows, dispatch coordination, and real
Integrated GNSS/NavIC hardware telemetry pipeline so location from ambulance units can be pushed to server
