Jamie Mill is a Lead Product Designer with 15 years’ experience crafting discovery-led experiences across startups and enterprise B2B products, now shaping analytics for Shopify brands at Polar Analytics from London. Comfortable switching between hands-on design, people management and strategic facilitation, Jamie has led rapid experimentation programs that seeded community-driven growth and built discovery practices used across teams. A practitioner of Lean UX, Jobs-to-be-Done and Indi Young’s mental models, they’ve institutionalised research workflows and taught methods like Event Storming and User Story Mapping to uplift product teams. Early front-end and back-end coding experience — including contributions improving CakePHP’s upgrade tooling — gives Jamie a pragmatic edge when pairing with engineers to ship iterative solutions. Known as a “walking method-bank,” they combine storytelling and technical fluency to simplify complex domains like pricing and B2B finance into actionable experience roadmaps.
