MedVault

Inspiration

Every family has faced this moment — a loved one needs emergency care, and nobody can find the old prescriptions or test reports. We experienced this personally, and it showed us a massive gap in global healthcare.

Less than 3% of people worldwide have organized digital health records. Prescriptions get lost, medicine schedules are forgotten, and patients repeat their entire medical history at every new doctor visit.

We built MedVault because we needed it ourselves.

What it does

MedVault is a Personal Health Record SaaS that gives every family a secure digital vault for their complete health history.

Smart Health Records — Upload and organize prescriptions, lab reports, and scans
Medicine Tracker — Track doses, set reminders, get refill alerts before stock runs out
Family Vault — Manage health records for your entire family under one account
Instant QR Share — Generate a secure QR code. Any doctor scans it and sees complete history
AI Health Summary — AI generates a plain-English health summary for any doctor visit
Bank-Grade Security — AES-256 encryption, only you control your data

How we built it

Frontend: Next.js 14 with App Router, TypeScript, Tailwind CSS, Vercel V0 for AI-assisted UI generation

Backend: Next.js API Routes, bcryptjs authentication, secure cookie sessions

Database: AWS DynamoDB — 5 purpose-built tables:

medvault-users
medvault-health-records
medvault-medicines
medvault-family-members
medvault-family-shares

AI: Claude by Anthropic for intelligent health summary generation

Deployment: AWS Amplify with CloudFront CDN

Challenges we ran into

Designing a DynamoDB schema that efficiently handles both relational family data and flexible health record structures
Building a QR sharing system with automatic expiry and security controls
Creating an AI summary that works across different types of medical records
Making the UI feel premium and trustworthy for a health application
