What I'm looking for

I’m looking for a healthcare integration role where I can drive HL7/FHIR and API delivery, partner with client and engineering teams, and apply my experience with SAML SSO, SCIM, and identity provisioning to improve reliable EHR interoperability.

I’m a technical implementation and solutions delivery engineer with 8+ years of experience working on healthcare integrations. My background includes supporting HL7 and FHIR integrations across platforms such as Epic and Oracle Cerner, while troubleshooting APIs, authentication work lows, and data issues.

At Unite Us, I support healthcare client implementations involving SAML SSO, SCIM, and JIT provisioning, along with API (REST) integrations and Epic/Cerner interoperability work. I troubleshoot API, authentication, and integration issues by reviewing logs, payloads, and application behavior across AWS environments, while managing multiple client implementations to keep onboarding tasks, technical work, and project timelines on track.

Previously at Cerner, I progressed from Interface Engineer to Senior Interface Engineer and Technical Engagement Leader. I led and supported HL7 interface development, testing, troubleshooting, and go-live activities, then partnered with interface engineers, solution architects, and client IT teams to coordinate escalations and keep healthcare integration projects moving forward.
