Background
Ambuvians identified a critical gap: in India's emergency healthcare system, calling an ambulance meant waiting on hold, hoping someone would pick up, with no visibility on where the vehicle was or when it would arrive. AmbuRakshak is their patient-facing app and dispatch backend — built to cut that gap to seconds.
The Challenge
Emergency software has zero tolerance for failure. The app needed to work under poor network conditions, handle concurrent dispatch events without race conditions, and deliver sub-60-second dispatch confirmations. Offline resilience and real-time GPS accuracy were non-negotiable.
Our Solution
We built a React Native app with an offline booking queue — bookings write locally first, then sync when the connection restores. The Node.js/Express backend uses an event-driven dispatch engine with Socket.IO rooms scoped to each active booking. Google Maps API handles live driver tracking and ETA calculation. MongoDB stores patient profiles, vehicle states, and booking history. VPS hosting keeps API latency under 80ms.
Key Deliverables
- Offline-first booking queue — works under poor network conditions
- Event-driven dispatch engine preventing concurrent booking race conditions
- Live Google Maps GPS tracking shared with patient and caregiver
- Sub-80ms API latency on VPS with real-time Socket.IO dispatch events
Results & Impact
How We Did It
01
Field Research
Shadowed emergency dispatch teams in two cities to map the exact failure points in the existing workflow.
02
Mobile Build
React Native app with offline-first architecture — bookings queue locally when network drops.
03
Dispatch Backend
Event-driven Node.js engine with Socket.IO rooms per active booking, preventing race conditions on concurrent dispatches.
04
Staged Rollout
City-by-city go-live with live monitoring dashboards and 24-hour on-call support during initial operations.
“Sageware understood the stakes immediately. They built something that actually works in real emergencies — not just in a demo environment. That discipline is rare.”
