About

I focus on building reliable systems and solving practical problems with technology. At North Consulting, I lead Engineering. On the side, I founded Valency, an AUSTRAC-registered crypto exchange, and co-founded OEX Timepieces, a watch company built around customisation. I like working through details, improving efficiency, and understanding how complex systems can be made simpler.
