Summary
David O'connell is an HL7 Integration Engineer with eight years as an independent consultant and a long history of hands-on implementation and support across hospitals and healthcare vendors. He specializes in extracting clinical and financial data for revenue cycle analysis, population health, and operational reporting, and has built custom web dashboards and multiple reporting systems to turn complex HL7, SQL and XML/XSLT integrations into actionable KPIs. David pairs deep interface-engine expertise (Mirth, Corepoint, IDX ConnectR) and ADT/DFT/ORU domain knowledge with practical systems administration skills across Windows, Linux, and network environments. He has led teams, introduced automation to replace manual workflows, and worked directly with executives and hospital IT to optimize deployments and compliance initiatives like Meaningful Use and Medicare ACO. An under-the-radar strength is his habit of shipping lightweight, open-source tools—such as a customizable mobile KPI dashboard—that make enterprise data more accessible to frontline users.
