FrontendReact interfaces that never render PHI beyond what a role is entitled to see, with no sensitive data cached client-side.
Backend & APIsNode.js, Python (Django, FastAPI) services with authenticated, validated, rate-limited endpoints.
Authentication & RBACMFA-capable auth, role- and attribute-based access control enforced server-side, not just hidden in the UI.
Tenant isolationRow-level or schema-level isolation so a query bug can’t leak one customer’s PHI into another’s response.
DatabasesPostgreSQL with encrypted connections, least-privilege roles and field-level encryption for the most sensitive PHI.
File storageEncrypted object storage with signed, time-limited access instead of permanently public URLs.
Audit loggingEvery read and write to PHI-bearing tables logged immutably, correlated to a user and a request.
Background jobs & notificationsAsync processing and notifications that carry PHI safely — no raw patient data in a push notification payload or a queue nobody encrypted.
Secrets managementCredentials and API keys in a managed secrets store, never in source control or plain environment files.
Cloud infrastructureAWS or Azure environments built with Docker and infrastructure as code, network-segmented from the start.
Monitoring & backupsHealth and security monitoring plus encrypted, tested backups as part of the initial build, not an afterthought.
Secure SDLCDependency scanning, code review and staged deployment gates so security holds as the team and codebase grow.
