About

I'm a versatile Unity developer specialising in medical and enterprise XR — a rare combination of deep technical skill and domain expertise in healthcare technology.

My work spans surgical planning tools, VR rehabilitation games, clinical examination systems, and multiplayer AR platforms. I'm comfortable owning a project end-to-end: from architecture decisions to Android native integration and performance profiling.

I've shipped products for Meta Quest, Microsoft HoloLens, custom VR headsets, and mobile platforms — with a strong focus on performance, reliability, and user experience in clinical settings.
