Working with Etc. Health at BT Group, I led the creation of Flex, a multi-library design system that empowers the HealthyYou healthtech product team with the speed and precision needed for rapid innovation. Flex includes Variable Modes—leveraging Figma’s variable capabilities—to allow for seamless dark mode designs in seconds, adding maturity and adaptability to the system. It also incorporates Slot Components for flexible, adaptable layouts across various use cases, ensuring consistent, scalable design practices while reducing design debt.
