View system →A single backbone, many surfaces
Every surface speaks to one NestJS API backbone (MongoDB · Redis · Socket.io). Real-time order tracking flows over WebSockets, asynchronous work runs on BullMQ queues, and Sentinel listens on an internal shared-secret channel so it can act back on the platform — blocking a lab or removing a phlebotomist the moment risk crosses the line.
Event-driven core
Redis Streams + BullMQ move bookings, payouts, reports and fraud events between services without blocking the request path.
Secure by design
JWT + 3-tier RBAC guards, AES-256 PII encryption at rest, full mutation audit trail and an internal-only action channel.
