UI/UX design · Three Index
Design that makes the build cheaper.
Research, flows, wireframes and interface design — sold standalone or with engineering — so what gets built is what users can actually complete.

What this covers
Concrete work we take on under ui/ux design — not a catalogue of buzzwords.
Wireframes and high-fidelity UI
Design systems and component libraries
Accessibility considered at design time
Problems we take on
If one of these sounds familiar, we have likely shipped something close — and we will say so if we have not.
Engineering is guessing because flows were never decided.
The UI looks fine in screenshots but fails on real tasks.
You need design without hiring a full-time product designer yet.
Who this is for
This is for teams whose engineers are guessing the flow, or whose screens look finished and still fail the task. The buyer may want design on its own, then engineering once the path is stable, or both from the same team.
The usual user is a busy operator: a counter, a coordinator, a reviewer, a finance lead. Consumer polish that hides the task is the wrong goal for that person.
How an engagement starts
Written scope
We write the tasks, the roles, and the decisions the interface has to support before high-fidelity screens. The scope says whether the deliverable is flows, wireframes, a prototype, or UI ready to build, and who will build it.
First increment
The first increment is one complete task drawn end to end, including the empty, error, and permission states engineering otherwise invents. Acceptance criteria travel with the screens so a handoff to your developers is buildable.
Decisions we make with you
Design-only is the right start when the flow is still unsettled and engineering time would be spent on the wrong path.
Design with build is the right start when the workflow is known and waiting on screens delays the release.
A design system is worth it when more than a handful of screens will share components and later work should get cheaper. A one-off visual for a single marketing page is a different job, and a specialist studio may be the better fit. Accessibility — contrast, focus, structure — is decided in the design, so the build does not audit it in after the fact.
What you own
You own the Figma files, the component library if one is in scope, and the written flows. Handoff includes annotations and acceptance criteria your engineers can implement. If we also build, the same files stay the reference for what shipped.

Where this shows up
The work shows up in tools people use under time pressure: a till and a stock count, an ordering desk, a financial operations screen. The interface has to finish the task on a busy shift, not only look coherent in a presentation.

Stacks we use when they fit the product and your team — not a mandatory toolkit for every engagement.

How we work
Scope first, named engineers, biweekly demos, and you keep the repo.
-
Scope before code
We write what is being built, what is excluded, integrations, dates and cost basis before the build starts. Changes get quoted before they get coded.
-
Talk to the people doing the work
You meet named engineers and designers. There is no account manager translating technical questions in both directions.
-
Working software every two weeks
Increments land on staging you can open and use. Progress you can click on beats progress in a status report.
-
You own everything
Repository, cloud account, domains and credentials stay yours. We work in your accounts wherever possible.
FAQ
Answers specific to ui/ux design — stacks, engagement and what we actually ship.
Design only, or design + build?
Either. Many clients start design-only and bring engineering in once flows are stable.
Do you hand off to our developers?
Yes — annotated Figma, components and acceptance criteria.
Do you create design systems?
Yes when the product will grow. Shared components and patterns keep later screens cheaper and more consistent.
Is accessibility included?
We design with WCAG-minded patterns — contrast, focus, structure — so accessibility is not an afterthought at build time.
What do we get at the end of a design engagement?
Flows, wireframes or high-fidelity UI as scoped, plus specs your engineers can build from without guessing.
