FHIR Prior Authorization Workbench
CRD, DTR, PAS and CDex end to end: the order, the payer's rules, the pre-filled form and the decision.
Showcase
Live systems, not slides. Each demo runs on its own host and sleeps when nobody is using it: start it here, and it is ready in a few minutes.
FHIR interoperability
Prior authorization on HL7 FHIR R4 and the Da Vinci guides, on a live system.
Java microservices for healthcare
Java 21 and Spring Boot labs on FHIR-shaped data: the same code we walk through in a debugger.
Prior-auth microservices (Java 21, Spring Boot, Kafka)
FHIR ServiceRequests and review Tasks across independent services, a gateway, circuit breakers and Kafka events.
Modern Java for FHIR Observations
Java 21 records, an enum carrying FHIR status codes, validation and Spring Data paging behind a small REST API.
Member portal: Postgres and a payer's Oracle
Members as FHIR Patients in PostgreSQL, Health Savings Account balances from Oracle stored procedures, Keycloak roles.
All data in these demos is synthetic. No real patient information is used.
