What it is
CoralEHR is an AI-native electronic health record for private-pay behavioral health — the flagship product of Simplest Healthcare. The thesis is simple: an EHR clinicians actually want to use, built alongside the people who use it rather than handed down to them.
How it’s built
- React + TypeScript on the front end, with React Query for caching and optimistic updates.
- An AWS serverless backend — API Gateway, Lambda, Cognito, HealthLake (FHIR R4), DynamoDB, and S3 — deployed with CDK.
- A FHIR R4 API layer with a strict resource allowlist and healthcare-grade access control:
RBAC via Cognito groups, ABAC enforced through FHIR relationships, and immutable
FHIR
AuditEventlogging on every read and write. - Shipped behind PR-gated CI/CD with Playwright end-to-end tests.
The AI part
Clinical AI agents run over HealthLake to generate outcome-driven progress reports, answer multi-turn questions about a chart (with DynamoDB-backed conversational state), and draft treatment plans from assessments and clinical notes — always with a clinician in the loop.
Beyond the code
CoralEHR was selected for the USC × Techstars University Catalyst pre-accelerator. I interviewed 80+ therapists to shape the workflows, and I lead both the engineering and a good chunk of the go-to-market — the kind of 0→1 ambiguity I like most.
