Scope
Overview
Marks & Spencer was losing ground online. The existing e-commerce platform couldn't keep up with modern customer expectations: slow page loads, friction-heavy checkout and a mobile experience that felt like an afterthought. They didn't need a facelift. They needed a complete rethink of how a heritage brand competes in a digital-first world.
My Role
Process
Led a cross-functional team of 20+ across London and Stockholm. We architected a headless commerce solution with a React frontend, decoupling the presentation layer from backend systems to enable rapid iteration. Accessibility and performance across all devices was the baseline, not a stretch goal. The checkout flow was redesigned from first principles, eliminating unnecessary steps while maintaining the trust signals that M&S customers expect.
Outcome
Shipped a new e-commerce experience serving millions of customers across web and mobile. Mobile conversion rates increased significantly, page load times cut by 60%. The platform became the technical foundation for M&S's ongoing digital work, proving that heritage brands can compete online when they commit to it.
