HL7 / Mirth CERTIFIED / Healthcare IT in the Cloud

United States

We do HIPAA-compliant HL7, EHR integration, healthcare analytics, lab integration, and HIE work. My tools are Mirth Connect, Java, C#,C++, and Python (all with JSON and/or XML involved). Increasingly, I am doing development in the cloud via Amazon Web Services. Hiring me involves getting a professional, a published author who speaks English, and who has held director or VP level positions four times. I have worked with HL7 since 2001, and implemented nearly every common transaction type for V2.x and V3. HL7 is not a framework that is learned over a few week or months. It is a career, with a training scope more similar to getting an extra masters degree. For instance, I had worked in HL7 for nearly 10 years, and I still took the semester-length course from the HL7 standards organization as continuing education. Warning to US HL7 clients: Organizations and individuals you hire outside the U.S. cannot be held accountable for HIPAA data breaches, at up to $50k per patient in fines
