01 — About
XR developer, tinkerer, amateur radio operator, lover of hard sci-fi. I love creating projects to learn new skills — from the i486 and Oculus DK1 to Star Trek-inspired interfaces.
I spent 6+ years as a Senior Software Engineer (XR) at Unity Technologies, where I architected spatial UX workflows, input systems, and cloud-connected tools for AR/VR platforms used by thousands of organizations worldwide.
I believe a better future is possible. Always moving forward, always learning. Captivated by XR, machine learning, and the rocks of silicon that we use to connect ourselves.
