Built for one practice.
Architected for hundreds.

LUKE isn't just an application — it's a platform. Multi-tenant by design, API-first by architecture, and built so the gap between customer one and customer one hundred is as small as possible.

Every tenant is an island.

Every table is tenant-scoped. Every query is tenant-filtered. PostgreSQL Row-Level Security enforces boundaries at the database level — not in application code, where mistakes happen.

Per-tenant encryption keys mean a compromise in one practice never touches another. Tenant-aware RBAC separates practice admins from platform admins. The isolation isn't a feature — it's the architecture.

Your EHR. Your pharmacy.
Your lab. Connected.

EHR Systems
Epic, Cerner

FHIR-compatible resource representations. The data model is structured so a FHIR adapter is a translation layer, not a rewrite.

Pharmacy Networks
Surescripts

Prescription routing and verification. Electronic prescribing workflows that keep the pharmacy loop closed and auditable.

Lab Providers
Quest, LabCorp, Health Gorilla, Getlabs

Order placement and results ingestion via Health Gorilla FHIR lab ordering. Getlabs at-home phlebotomy for patient convenience. Structured lab data flows directly into patient records without manual transcription.

Payment Processing
Stripe

Native integration with webhook idempotency. Payment state is always consistent, even when webhooks arrive out of order.

Versioned public API with OAuth2 client credentials. Webhook subscriptions for clinical events. Every integration point is designed to be extended, not forked.

A real API. Not an afterthought.

api/v1/patients
POST /api/v1/patients
Authorization: Bearer {oauth2_token}
Content-Type: application/json

{
  "first_name": "Sarah",
  "last_name": "Mitchell",
  "email": "sarah@example.com",
  "intake_form_id": "form_8x4k2m"
}
  • OAuth2 client credentials — machine-to-machine authentication with scoped tokens
  • Versioned endpoints — breaking changes never ship to existing consumers
  • Webhook subscriptions — real-time notifications for clinical events and state changes
  • FHIR-compatible resources — structured health data representations that translate cleanly
  • Comprehensive error responses — structured errors with codes, messages, and remediation hints
  • Rate limiting with clear headers — predictable throttling with X-RateLimit headers on every response

Production-grade.
Not prototype-grade.

FastAPI on Cloud Run

Auto-scaling from zero to whatever the load demands. Zero-downtime deployments with revision management and instant rollback.

PostgreSQL on Cloud SQL

Asyncpg connection pooling for high throughput. Read replica ready for analytics workloads that shouldn't touch the primary.

Redis on Memorystore

Cache layer with graceful fallback to direct database queries. The application works without Redis — it just works faster with it.

OpenTelemetry

Distributed tracing to Cloud Trace. Structured logging with correlation IDs that follow a request from ingress to database and back.

Secret Manager

Credentials stored in GCP Secret Manager. TTL-based cache refresh means rotation doesn't require redeployment.

CI/CD Pipeline

Full test suite on every PR. Lint, PHI detection in logs, and pip-audit for dependency vulnerabilities. Merged code is deployed code.

The platform gets smarter
as it grows.

Lead scoring that improves with every practice on the platform. Anonymized, aggregated conversion data across tenants trains models that new practices benefit from on day one.

That's a network effect — the platform gets better as it grows. Analytics caching already supports cross-tenant insights. The data advantage compounds, and it belongs to the platform.

What happens at 2 AM matters.

272
Automated Tests

Security, encryption, concurrency, and integration suites. Not just coverage metrics — tests that catch the failures that happen in production, not in theory.

Staging Environment

Full replica with synthetic data. Every deployment passes through staging before it touches production. No exceptions, no shortcuts, no "just this once."

Observability

P50/P95/P99 latency tracking. Error rates, connection pool utilization, cache hit ratios. The dashboards exist before the incidents do.

On-call Runbooks

Database pool exhaustion. Stripe webhook failures. Cross-tenant data reports. Documented procedures for every known failure mode.

Automated Breach Detection

Four detection patterns running continuously: bulk PHI access, after-hours activity, failed authentication spikes, and unauthorized access attempts. Alerts fire before damage compounds.

20 versioned schema migrations tracked in migration history. Database evolution is managed, not improvised.
