Engineering Radiology’s Front Door — Building the systems that connect imaging, AI, and patient care.

See My Work

What I Build

I focus on creating platforms that merge deep technical precision with human-centered workflows — from cloud-native DICOM pipelines to real-time, GPU-accelerated viewers that redefine how radiologists interact with images.

Sirona Medical — Leading engineering across the radiology stack: Viewer, AI, and QA. Driving performance, scalability, and developer excellence in healthcare imaging software.

Zillow Group (Dotloop) — Built and scaled systems powering millions of real estate transactions, guiding teams through modernization and architectural evolution.

How I Lead

I believe leadership is about clarity, empathy, and momentum. I build teams that balance innovation with discipline — engineers who understand not just the code, but the context. My approach emphasizes sustainable velocity, transparency, and cross-functional trust.

Themes I Care About

Beyond Work

Outside of engineering, I enjoy exploring the intersections of art and technology — from building small creative tools to designing escape rooms and helping others unlock potential through mentorship. I’m also a husband, dad of three, and occasional lake explorer in Michigan’s Upper Peninsula.

Let’s Connect

If you’re building something at the intersection of healthcare, imaging, or scale — I’d love to connect.
