Professional story

Healthcare integration work, grounded in implementation reality.

I started my career at Epic Systems as a MyChart Technical Services engineer, where I learned how patient experience workflows, health system operations, and real-world EHR implementation constraints fit together. That foundation shaped how I approach technical work: the system has to function, but it also has to support the people trying to deliver care.

At Luma Health, I grew into healthcare startup integration work across EHR connectivity, implementation delivery, escalation support, and customer-facing problem solving. I spend a lot of time in the intersection between engineering, delivery, support, and customer success—translating ambiguous problems into clear next steps and helping teams get live with confidence.

My strongest work happens in the gray area where technical systems, customer needs, and operational reality meet. I care about reliability, clarity, ownership, and practical problem-solving: understanding the workflow, making invisible behavior visible, and staying with the problem until the outcome is dependable.

What I do

Turning messy integration problems into dependable production outcomes.

The work spans technical investigation, workflow understanding, customer communication, and implementation delivery.

EHR Integrations

Designing, validating, and supporting healthcare integrations that connect products to real clinical and patient-access workflows.

API & FHIR Workflows

Working through API behavior, FHIR resources, payload validation, edge cases, and implementation details that affect production reliability.

Epic & Oracle Health/Cerner Connectivity

Supporting integrations in Epic and Oracle Health/Cerner environments with an understanding of EHR operations and customer constraints.

Implementation Troubleshooting

Debugging go-live blockers, production issues, escalations, and ambiguous defects with a calm, structured, first-principles approach.

Data Mapping & Workflow Design

Translating operational requirements into data mappings, configuration decisions, and workflows that teams can maintain.

Customer-Facing Technical Leadership

Communicating clearly with technical and non-technical stakeholders, building trust, and keeping delivery moving through uncertainty.

Experience highlights

Built in health systems, sharpened in startup delivery.
