BloodLink — Blood Donation Platform — architecture overview

01 — The problem

Finding a matching blood donor in time still happens through phone chains and social media posts. The information exists; it is just not in one place when it is urgently needed.

02 — Our solution

A platform where requests and donors meet directly, with the state of a request visible in real time so nobody is left guessing whether it has been fulfilled.

Architecture

How it works

The pipeline, step by step — from the first input to the final output.

  1. 01

    Requests

    Recipients post a blood request with the details that matter for matching.

  2. 02

    Donors

    Donors register and are matched against open requests.

  3. 03

    Tracking

    Request status updates in real time as donations are committed.

Engineering notes

Challenges we solved

Urgency shapes the interface

Someone using this is under stress. Every extra screen between a request and a match is a real cost.
