Product Design

Design and engineering run in parallel on every engagement, so a design decision's implementation cost is visible while it's still cheap to change — not discovered during a sprint three months in.

FigmaDesign TokensStorybook

Design that ignores engineering cost creates rework. We run design and engineering in parallel, so the price of a design decision is visible while it is still cheap to change.

We start from real usage data where it exists and from conversations with your users where it does not. The output is a component-level design system with tokens and documented states, not a folder of one-off screens that drift from the build.

Clickable prototypes are tested with target users before build sign-off, and design QA continues through implementation, so what ships matches what was approved.

What's included

UX research and flow mapping grounded in real usage data where it exists
A component-level design system, not a one-off set of screens
Clickable prototypes tested with real target users before build sign-off
Design QA through implementation, not a handoff document that goes stale

What changes in the codebase

balance.ts

 export async function getBalance(userId: string) {
−  const res = await fetch(`/api/legacy/balance/${userId}`);
−  return res.json(); // no retry, no timeout, no typed shape
+  const res = await client.balances.get(userId, {
+    retry: 3, timeoutMs: 2000,
+  });
+  return BalanceSchema.parse(res);
 }

We can, but the work is stronger when the same team ships it. Design-only engagements are possible when you have an engineering team ready to build.

A tested prototype, a component library in Figma with design tokens, and specs your engineers can build from directly.

Yes. We audit key flows against analytics and user sessions, then fix the highest-impact friction first.
