Case Study
Quinine Design System
Tonic.ai
I built Quinine as Tonic's internal design system to replace weak early frontend patterns, UI drift, and painful legacy components with a modernized and cohesive product foundation. It became the default way we built product UI, reduced ad hoc CSS and misconfigured patterns, and made ordinary feature work much faster for engineers.
