Health Cloud Data Sync:
- Established bi-directional patient data flows
- Configured clinical alerts for care teams
- Automated care plan updates back to EHRs
Zero-Downtime Architecture:
- Implemented failover protocols for EHR outages
- Created data reconciliation workflows
- Built monitoring dashboards for all interfaces
