Technologist. Builder. Leader.
About Me
I’ve spent more than twenty-five years working at the intersection of technology, strategy, and delivery, building things that matter, for organisations that matter. My career has taken me from hands-on infrastructure engineering in the early days of the internet, through the cloud revolution, and now into the age of AI.
Most recently I was a Solutions Architect at Amazon Web Services, where I partnered with the United Nations and Australian Public Sector and Defence organisations to design and deliver cloud solutions at global scale. That work gave me a deep appreciation for what technology can do when it’s applied to genuinely important problems, and for the gap that still exists between what’s possible and what’s actually being built.
That gap is what led me to found Adjacent Possible Tech. I’m building myEdi.ai, an AI-native educational platform designed to give every child access to personalised, adaptive learning. It’s the most ambitious thing I’ve ever worked on, and the most important.
Before AWS, I spent two decades across a range of technical and leadership roles in Big Tech companies, serving public sector and enterprise customers. I’ve led project teams of 3 to 25 people on multi-million dollar, multi-year delivery programmes — building platforms, shipping products, and bringing complex technical programmes from concept through to production.
I write here about the mental models, ideas, and experiences that have shaped how I think about building technology and building a career.
What I’m Looking For
I’m interested in applied AI and ML roles, whether as an individual contributor building intelligent systems, or in a leadership capacity shaping AI strategy and delivery. I want to work on problems where AI creates genuine, measurable impact, not just incremental automation. Open to both IC and leadership positions, remote or hybrid.
