Problem
Emergency medical personnel need instant access to a patient's vital health details (allergies, chronic illnesses, emergency contacts) when the patient is unconscious or unable to speak, but traditional records are siloed.

Solution
Medivita encrypts patient medical records locally with AES-256-GCM and generates temporary JWT-signed QR codes that emergency staff can scan to securely and instantly view essential health data.
Overview
What I Built
Medivita is a portable digital medical record platform powered by Next.js and Supabase. Patient health data (blood type, allergies, chronic illnesses) is encrypted using AES-256-GCM before entering the database. Healthcare providers scan dynamic QR codes containing JWT-signed tokens to instantly decrypt and view vital patient info in medical emergencies.
