Timeline
9 months, phased rollout across 40 clinics
The Business Problem
Meridian's electronic health record system was running on an unsupported on-premise stack, unable to meet modern interoperability mandates and increasingly prone to scheduled and unscheduled downtime affecting patient care across 40 clinic locations.
The ORYNZEX Solution
ORYNZEX designed and delivered a phased modernization: a cloud-native patient records core built on Spring Boot and PostgreSQL, a FHIR-compliant integration layer for provider interoperability, and a zero-downtime data migration strategy executed clinic-by-clinic over nine months.
Architecture Overview
- Multi-AZ AWS deployment with automated failover across regions
- FHIR R4 API gateway for EHR interoperability with partner systems
- Event-driven audit logging for HIPAA compliance and traceability
- Blue-green deployment pipeline enabling zero-downtime releases
