• Administered and supported production HL7 v2.x interface integrations for 70+ hospitals across 3 InterSystems IRIS/Ensemble production servers in a HIPAA-compliant, 24x7 mission-critical healthcare environment.
• Built and onboarded new HL7 interface connections end-to-end — including interface line creation, configuration of Business Services, Business Processes, and Business Operations in Ensemble/IRIS, integration testing, and go-live validation for incoming hospital systems.
• Maintained high-throughput HL7 message pipelines processing 200+ messages per hour (ADT, ORM, ORU) via MLLP protocol, ensuring 24x7 SLA compliance across all hospital integrations and downstream clinical systems.
• Developed, modified, and tested DTL transformations and Object Script-based routing rules to meet evolving clinical workflow requirements; managed versioning and change-controlled deployment of all transformation updates.
• Managed SFTP-based file interfaces for daily send and receive operations between hospital trading partners and downstream clinical platforms, ensuring reliable and timely file delivery via TCP/IP connectivity.
• Handled CCD / C-CDA file-based interfaces — managing receive and send operations through Ensemble production workflows between clinical systems including EHR, LIS, and RIS platforms.
• Resolved up to 10+ P1/P2 production incidents per month using IRIS/Ensemble logs, queue inspection, and Linux-based shell diagnostics — consistently restoring HL7 message flow within defined SLA resolution windows.
• Monitored interface message queues, performed controlled message reprocessing, and resolved queue exceptions — maintaining data integrity and zero HL7 message loss across the multi-hospital integration network.
• Diagnosed and corrected HL7 message structural and data-level errors; managed ACK/NACK acknowledgement failures to ensure reliable message delivery between sending and receiving clinical systems.
• Coordinated with downstream hospital IT and clinical teams during system outages — acted as integration point-of-contact for incident bridges, status communication, and message flow restoration.
• Executed SQL queries against InterSystems Cache and backend clinical databases for data validation, reconciliation, and targeted corrections in HIPAA-compliant environments.
• Authored and managed ITIL change requests in ServiceNow; participated in CAB meetings for production change approvals, risk assessment, and deployment planning.
• Provided rotational shift and on-call support for mission-critical healthcare integrations across multi-hospital network environments, maintaining SLA adherence across time zones.
