UI/UX & Product Design

Design done before the build, not bolted on after it — buyable on its own.

from €1,450

UI/UX & Product Design — devexpertsstudio

The Problem

A product that works but looks and reads as amateurish loses deals, loses trust, and loses users to a competitor that simply looks more credible. Design retrofitted after development costs more — and does less — than design done first.

  • Users get the job done, but say the product "feels unfinished" without being able to say why
  • Every new feature gets a slightly different visual treatment because there's no system
  • Design decisions get made by whoever's writing the code that week

What's Included

Research grounded in your actual users

not assumed personas.

A tested design

not a first-guess mockup — usability-checked before it's called final.

A design system, not a page

so new screens stay consistent without a designer re-deciding every detail.

Files and specs any developer can build from

Figma handoff, no proprietary format.

Accessibility built in, checked against WCAG 2.2

not addressed after launch.

Who It's For

Perfect for

  • Teams whose product works but doesn't look credible enough to close the deal it's in
  • Founders about to commission a build who want the design settled first
  • Anyone who wants to buy design independently of a build package, from us or anyone else

Outcomes

  • A product that reads as credible on the first screen a user sees
  • A design system that keeps every new feature visually consistent without re-deciding it
  • Files a developer — ours or yours — can build from without guesswork

How This Engagement Runs

Survey

We use the product (or the brief, if greenfield) the way a real user would, and talk to actual users where they exist.

Specification

What's in scope — which screens, which flows, which components — is written down and priced.

Build

Design work happens in the same weekly-demo rhythm as a code build: you see progress, not a single reveal at the end.

Verification

Usability-tested before it's called finished, not assumed to work because it looks right.

Handover

Files, documentation and component specs transfer on final payment — usable by any developer, not locked to working with us.

Frequently asked

Do I have to buy a build package too?
No. This is the one service on the site built to stand alone — buy the Design Audit or a full Design System and take the output to any developer, including your own team.
Can you design for a product that doesn't exist yet?
Yes — Product Design Sprint is commonly bought before a build, so the interface is settled before development starts. It pairs naturally with MVP & Product Development or Web Application Development.
What does "developer-ready" actually mean?
Structured Figma files, a documented component list, spacing and type tokens named consistently — no guesswork about pixel values or which screen is final.
Do you run usability tests with real users, or internally?
Real users where you can provide access; a small representative panel where you can't. Either way, the design is tested before handoff, not assumed correct.

Design settled before a line of code gets written.
