Healthcare Data Architect

FHIR Advisor & Author

I help organizations and national programs make the right architectural decisions on healthcare data projects, before those decisions become expensive and difficult to fix. I specialize in FHIR interoperability, CDRs, analytical platforms, master data management, and terminology.

I’ve worked with Olympus, Optum, BCG and others. I’m fully independent, with no commercial ties to any vendor you work with or are evaluating. My advice is unbiased.

Speaking at FHIR DevDays in Amsterdam in 2025

“Darren’s deep FHIR knowledge has been invaluable in optimising our focus and avoiding common mistakes in getting state claims into the federal database. His generosity of domain knowledge has made our initial implementations higher quality, and contributed to faster and better healthcare to the 175MM people who rely on Medicare/Medicaid.”

Laura Lanford (Senior Director, Engineering)

“Darren’s deep expertise in FHIR standards was instrumental to our project’s success. He consistently demonstrated not only technical mastery of the specification but also the practical wisdom to guide implementation decisions that balanced standards compliance with real-world constraints.”

Paul Urban (Lead Platform Solution Architect at Olympus)

I’m Available for Hire

Healthcare data programs fail for predictable reasons: weak architecture decisions or decisions made in the wrong order; vendor choices that create architectural problems, lock-in, or capability gaps; ambiguity around source-of-truth for patient or clinical data; programs that lose direction half-way through. I’ve seen all of this and more.

I’m brought in when organizations need senior input on decisions that are difficult to reverse. Sometimes that’s a single focused engagement. Sometimes it’s as a long-term advisor to technical and project leadership.
