17 years across NZ, UK & globally
I gained a BSc Honours in Computer Science at the University of Brighton, England. Over the past 17 years, I've shipped 22+ apps across iOS, Android, and React Native — reaching over 30 million users and earning 5 industry awards along the way.
My work spans blue-chip brands including Coca-Cola, Pret, Marsh, Unilever, BMW, Audi, VW, and Vogue — delivering bespoke mobile solutions across the FTSE 100 and beyond.
I've helped generate over $500 million in annual revenue for PushPay and £450 million for Domino's Pizza. The Domino's app was named Brand of the Decade at the EMMA Awards, and the Mercury Energy app hit #1 on the NZ App Store in 2023.
Beyond code, I compose, write, and produce music — with a solo album to show for it — and spent two years as a professional retoucher, graphic designer, and photographer. That creative life isn't separate from my technical work; it's what sharpens my eye for detail and drives my obsession with craft.
