blood donation platform

What is it?

A mobile platform that automatically connects blood donors with hospitals in Algeria during urgent needs — replacing the current chaotic system of Facebook posts and mosque announcements.

The Problem It Solves

Algerian hospitals struggle to find blood donors quickly. Right now, when blood is needed urgently, hospitals post on social media and hope someone sees it. This is slow, disorganized, and can cost lives.

How the Platform Works

For Donors (Mobile App):

Register with Firebase Auth (email/phone)

Create profile: blood type, age, weight, location, health info

App automatically checks eligibility (age 18-65, weight 50kg+, 90+ days since last donation, no disqualifying health conditions)

Toggle "Available" when ready to donate

Receive push notifications when a nearby hospital needs their blood type

Accept or decline the request

If accepted, get hospital contact info and directions

For Hospitals (Web Portal):

Login and create a blood request (blood type + urgency level + how many units)

System automatically searches the database for eligible, compatible, nearby donors

Push notifications sent instantly to all matching donors

Hospital sees who accepted in real-time and contacts them directly

Behind the Scenes (Backend):

Blood compatibility matching (e.g., O- can donate to anyone, AB+ can receive from anyone)

Distance calculation (Haversine formula) to find donors within a chosen radius

Eligibility filtering happens at the database/query level before anyone gets notified — so only real, eligible donors are contacted

Firebase Cloud Messaging delivers the push notification within seconds
