LX Medical runs a telehealth clinic providers, patients, appointments, payments, and consent, all managed through one admin platform. The people who keep the clinic running spend their entire day inside it. But the platform had grown the way products do when features get added faster than they get organized. Screens were crowded, actions were buried, and the same information showed up in three different visual styles across the app. It worked but working in it was harder than it needed to be. I came on as the sole product designer for the whole platform. Not a screen here and there the entire surface, plus the design system underneath it. My approach started with the foundation. Before redesigning a single screen, I built a proper design system: a full semantic color scale, a complete type scale, an icon library, and a set of reusable components. Everything that came after was built from it, so the platform would finally feel like one product instead of a dozen screens designed at different times. Then I worked screen by screen appointments, booking, billing, consent, scheduling rethinking the structure of each so an admin could get in, see what needed doing, and do it, without hunting.
