About

Rendering the future,
one pixel at a time.

I'm a Senior Principal Engineer and Technical Director with a career spanning AAA games, real-time graphics research, and cutting-edge platform development. From Grand Theft Auto IV at Rockstar North to MetaHumans at Epic Games, I've spent over two decades pushing the limits of interactive graphics.

As Director of Technology at Spliced Inc. (2022–2026), I architected graphics and engine systems across mobile, PC, and console platforms using Unreal Engine. Before that I held principal and lead roles at NVIDIA Omniverse, Epic Games, Snap, and Rocksteady Studios.

I'm now available for senior contract and fractional CTO engagements — whether you need deep graphics expertise, Unreal/WebGL architecture, mobile optimisation, or technical leadership.
