Project Goals
Accessible by design
Built to meet accessibility standards consistently across all brands.
Simpler onboarding
A consistent, intuitive structure made it easier to bring new brands onto the platform.
Analysis
As this was a rebuild, a significant amount of analysis was required. Much of the documentation from earlier projects was redundant or misplaced, so the only reliable route was to work with product owners, business analysts and developers to uncover years of accumulated logic and rules.
We were also moving from an adaptive solution to a responsive one while the existing mobile and desktop experiences were not always consistent.
Design System
Design tokens became the foundation for scaling the system across brands and markets, with variables introduced as the platform matured.
To keep design and implementation aligned, Storybook connected coded components with the shared Figma styles and patterns.
Build, Validate, Approve
A major focus of delivery was reducing duplicated build effort across multiple estates. Shared foundations and reusable modules accelerated implementation while improving consistency and maintainability. Moving toward one unified platform meant less time rebuilding solved patterns and more time improving the experience itself.
I carried out validation throughout the process, from early concept checks and journey reviews to regression testing and live-trading confidence checks.
Impact
Platform Modernisation delivered measurable improvements across experience, performance and operational efficiency.
Once the foundations were in place, new work could be delivered in hours rather than weeks, enabling rapid onboarding and consistent delivery across markets.
