Senior Software Developer contractor

• Converted an US Army battlefield hospital HL7 integration system from using the Cloverleaf integration engine to the Iguana HL7 integration engine. The system required a real-time mobile RF-based integration between medical personal on the battlefield and the HL7 system and the forward operations base hospital. The mobile communication were built on packet radio, using IP over shortwave. The mobile interface allowed field medics to send HL7 messages from the battlefield to obtain patient information and to schedule emergency procedures at the base hospital. Additional, the system would generate continuity of care documents for each patient treated in the field. HL7, Spring MVC, JavaScript, MySQL
• Implemented an HL7 bridge between two heterogeneous systems for the US Navy to ensure seamless information flow between either of them. Work flow integration was required to ensure that state and transactional changes were reflected in corresponding systems. The Health care applications that were integrated include Practice Management Software with the ability to manage the Appointment Scheduling and end to end billing activity for a US Naval base physician's practice and an EMR management application with the ability to manage the clinical workflow of the base medical practices. The appointments and patient information on change is delivered to the EMR system to update the physician's schedule and at the end of the office service. HL7, PHP, JavaScript, MySQL
