Blood cannot be manufactured. It comes only from a voluntary donor, and Malaysian hospitals face recurring shortages, especially of rarer groups. Yet when a patient needs blood urgently, the appeal is still spread by hand: WhatsApp forwards, Facebook posts, word of mouth. Such appeals are untargeted. They reach thousands who are not clinically able to help, while the compatible donor a few kilometres away may never see the message. Time is lost exactly where time matters most.
"Right Donor, Right Time" replaces this guesswork with verified, blood-type-matched, location-aware alerting. It has four parts: a donor mobile app, an administrator mobile app for on-site work at drives, an administrator web console for back-office work, and a serverless backend shared by all three.
Its core innovation is the emergency workflow. A member of the public submits a request stating the patient's blood type and hospital, with a supporting hospital document attached. An administrator verifies that document and approves or rejects it. On approval the system does not broadcast: it applies the clinical compatibility rule (an A+ patient, for example, can receive from A+, A-, O+ and O-) and sends a high-priority push only to donors whose blood can actually save that patient, prioritised by proximity, while the wider community is informed at normal priority. Every alert therefore reaches someone able to act on it, so alerts are not dismissed as noise.
The platform also solves the two everyday problems that keep donor supply low. Donors find nearby donation drives on an interactive map sorted by distance and reserve a place in advance. At the event, an administrator identifies the donor by scanning a permanent QR "blood number" and records the donation digitally, replacing paper forms and scattered spreadsheets; the donor's full history is then instantly available on their phone. The whole platform, notifications included, is delivered in English and Bahasa Melayu.
A review of Pusat Darah Negara, the American Red Cross Blood Donor App and NHS GiveBlood shows each is strong in its own area, but none combines a publicly raised, document-verified emergency request, clinical blood-type matching, location-aware event discovery and a bilingual Malaysian design. That combination is what this platform delivers, and it runs on a serverless architecture at no infrastructure cost at this scale, making it adoptable by hospitals, NGOs and state blood banks, not merely demonstrable.
