The Product Buy Box
One buy box, two pack sizes, five stock statuses and a VAT toggle. How I redesigned Drinkstuff's product page to sell by the case without confusing anyone.

CSPO / UX / UI / Vision / Strategy
Welcome! I'm Duncan Hann, and this is where I share my work, ideas, and everything I've been learning along the way. My background is in product design and eCommerce, with experience across product management, UX, and front-end development, areas I enjoy and continue to develop my skills in.
I'm based in Welwyn Garden City, Hertfordshire, and work with retail and ecommerce teams across Hertfordshire, London and Cambridge.
You'll find a mix of projects, thoughts, and hands-on experimentation, all with a focus on building simple, effective solutions that genuinely help users.
This site is also a working example of my front-end development skills, built using Eleventy (11ty) and driven by curiosity.
