What I'm looking for

I'm looking to build and validate XR, interactive, or developer-facing products where I can combine prototyping, automation, interaction design, customer feedback, and technical storytelling.

I've built XR interactions, automated test systems, and technical demos across Microsoft, Meta Reality Labs, Apple, Hololight, Croquet, and Cisco.

At Meta Reality Labs, I co-designed and implemented near-field and distance-grabbing systems for Horizon Worlds, built dynamic player scaling, and owned automation for hundreds of Quest, Quest Pro, and Ray-Ban Stories devices.

At Apple’s Technology Development Group, I developed mission-critical automation validating Measure accuracy across iOS devices and helped standardize XR accuracy verification for ARKit, Reality Composer, ARQuickLook, and RealityKit teams.

I’ve also led North American technical sales for enterprise XR streaming at Hololight, built Unity-to-JavaScript messaging infrastructure at Croquet, and automated game performance testing and interactive dashboards at Microsoft.
