I build tools for healthcare interoperability and clinical data engineering, focusing on HL7v2 interfaces, CCD/C-CDA parsing, FHIR validation, de-identification, and real-world EMR integration workflows across Epic, Meditech, Cerner, Athena, and eCW.
I also build browser-based simulations and observatories for emergent behavior and complex systems.
OpenAI profiled one of my interoperability workflows in Chats for Scientists and later included a healthcare data exchange prototyping use case in the March 5, 2026 ChatGPT for Pros newsletter.
