About Me

With over a decade of engineering experience that began at Microsoft, I’ve transitioned from a full-stack role to specializing in iOS and visionOS development. My focus is on cutting-edge augmented reality (AR) apps for a diverse set of clients and startups, spanning prototyping, research, and polished product delivery—including one of the first Apple Vision Pro apps.

My broad background lets me tackle complex iOS and AR challenges with a unique perspective, leveraging deep expertise in ARKit, Swift, SceneKit, and SwiftUI. I’ve fully owned iOS projects from ideation to App Store release, ensuring every aspect—from design and development to testing and deployment—meets the highest standards.

If you’re looking to break new ground in mobile or AR, I’d love to discuss how we can collaborate on your next venture.
