UI design, every variant defined, every state designed, engineering builds what designers approved.
UI design is where the brand and the product meet the user. We design every variant of every component, every state of every screen, happy path, empty, loading, error, so engineering builds the version that was approved, not their reasonable interpretation of it.
What we build
Component-first design, screen-second
Buttons, inputs, cards, modals, designed and variant-mapped before screens get assembled. New screens compose existing components 80% of the time; the 20% that needs new components grows the system deliberately.
Tokens that match the engineering config
Spacing, color, type, radius, defined in Tokens Studio, mirrored in the Tailwind config. Pixel values appear nowhere in the Figma file or the codebase. A token change in design ships to production in the same PR.
Every state designed, not just the happy path
Loading, empty, error, partial-data, offline, permission-denied. The engineer doesn't have to invent the failure mode; it's in the file, with copy.
Responsive across the real breakpoints
We design at the breakpoints the product is actually used at, not just 360 and 1440. The mid-range (1024–1280, the laptop range) gets explicit attention because that's where ops tools live.
Accessibility as a constraint, not an audit
Contrast checked per token combination, focus rings specified per component, hit areas sized for touch. The screen design and the a11y pass aren't sequential, they're the same activity.
Motion specified alongside the static frame
Hover states, transitions, micro-interactions, defined with duration and easing tokens, not 'snappy'. The motion track lives next to the visual track in Figma.
Where this fits
Your designers and engineers ship close-but-not-the-same versions of every screen and the QA cycle is the bottleneck.
You're shipping a major UI refresh and you need the whole component matrix designed end-to-end, not screen by screen.
Your product is past the prototype stage and the UI debt is starting to show.
