13: System Blueprint

HeartTrack v2 can scale into a production-ready cloud architecture:

  • Frontend: React Native for iOS and Android.
  • Backend: AWS microservices built with NestJS (Node.js).
  • Identity: Keycloak managing OAuth 2.0 and JWT flows.
  • Database: PostgreSQL on Amazon RDS with encryption.

Infrastructure as Code is handled via Terraform, with CI/CD pipelines running through GitHub Actions.
