Problem

Problem

Emergency routing suffers when ambulance status, hospital load, and route intelligence are fragmented across disconnected systems.

Constraints

Constraints

High concurrency, low-latency location updates, and reliable data propagation during peak usage where delays directly affect outcomes.

Approach

Approach

Implemented GPS live tracking, traffic-aware routing, ETA estimation, nearest-hospital selection, and efficient Firestore sync for concurrent sessions.

Outcome

Outcome

Reduced response-time friction and enabled better dispatcher and hospital visibility under load with stable, real-time cross-device updates.

What I’d redo

What I’d redo

Add simulation tooling for surge scenarios earlier to validate scaling thresholds and fallback strategies before production-like stress.
