SevaLink
Emergency Ambulance Dispatch Platform for India
A production-grade system inspired by Uber's dispatch model — built entirely from scratch. Patients request ambulances, drivers are dispatched via a serial-offer algorithm with radius expansion, hospitals receive auto-appointments, and payments are processed via Cashfree Easy Split. Everything is real-time via Socket.IO.
