I'm Eugene Vestel. Through consulting, open-source tools, and the Out of the FHIR podcast, I help teams navigate healthcare interoperability and turn data into outcomes.

What “quality measurement” looks like when it stops being a slide.

Open Source
A guardrail layer between AI agents and health data, a personal care agent built on top of it, and an open corpus of the quality measures the whole industry keeps rewriting from scratch. All open, all running.
A security layer between AI agents and clinical data. Redacts PHI on every read, enforces multi-step human approval for clinical writes — proposal, permission evaluation, HMAC confirmation, immutable audit log — and keeps your health agent interactions HIPAA-compliant.
Spin up a personal health agent in under a minute. Every read redacted, every access audited, every action approved by you — guardrailed by HealthClaw. This is what the guardrail layer looks like once a person is actually using it.
An open, MIT-licensed corpus of healthcare quality measures with verified provenance, plus a typed record of what implementers have actually learned about each one. CQL and SQL alongside the measure, not buried in a PDF.
An ongoing analysis of the CMS health tech ecosystem and the national provider directory modernization effort. Mapping the players, the standards, and the FHIR-based architecture behind the next-generation healthcare directory.
