DUTCH HOSPITAL NETWORK

Designed a federated data mesh architecture on Databricks Unity Catalog, allowing each hospital to retain data ownership while sharing curated datasets through governed data products

Implemented Databricks Delta Sharing for secure, open-protocol data exchange between hospitals — enabling cross-facility analytics without requiring data duplication or centralisation

Built FHIR-compliant data pipelines on Databricks integrating with Epic, HiX, and ChipSoft clinical systems using Delta Lake medallion architecture

Deployed AI models for patient flow prediction, readmission risk scoring, and resource demand forecasting using Databricks ML and MLflow

Implemented differential privacy techniques and AI-driven anonymisation layered on top of Delta Sharing for cross-hospital analytics without exposing patient-level data

Deployed on Azure with Databricks private endpoints and managed identity for zero-trust security

Connected 8 regional hospitals with 12,000+ beds into a single Databricks-powered analytics fabric via Delta Sharing

Delta Sharing enabling real-time cross-hospital data collaboration without data replication — maintaining sovereignty per facility

AI-driven patient flow predictions improving bed management

Enabled cross-facility benchmarking that identified 15% improvement opportunities in patient throughput

Maintained full GDPR and NEN 7510 compliance with zero data-sovereignty violations
