UI/UX & Product Design

End-to-end product design — research, flows, prototypes, interface and design systems — done with the engineers who will build it, so the design ships rather than stalls in handover.

Overview

Product design is problem-solving, not decoration. Before anyone chooses a colour or draws a screen, the real work is understanding what a person is trying to get done, where they currently get stuck, and what “finished” looks like for them. Good design starts there and stays there — measured against task success, conversion, fewer support tickets and less abandoned effort — not against whether the designer found it pretty. Taste is real and it matters, but taste that is not anchored to a user’s problem is just an expensive opinion, and we will not sell you one.

This is our broad, end-to-end offering: user research, information architecture, user flows, wireframing, interactive prototyping, visual and interface design, design systems, usability testing and accessibility, run as one continuous piece of work rather than a relay of specialists throwing artefacts over a wall. It sits above our narrower UX Design, UI Design and Web Design services — you come here when you need the whole arc from an unclear problem to a designed, buildable product, and to a system that keeps it coherent as it grows. If you only need one slice of that, the narrower service is the honest, cheaper answer, and we will point you at it.

The thing that separates us from a studio that makes lovely mockups is that our designers work with our engineers throughout, not at the end. A design is not finished when it looks right in a prototyping tool; it is finished when it is built, shipped and doing its job for real people on real devices. Designs that ignore the cost of what they ask for — the edge cases, the empty states, the loading and error conditions, the thing that is trivial to draw and brutal to build — die quietly in handover and get rebuilt into something worse by a developer under deadline. We design so that does not happen.

Who it’s for — Teams building or reworking a product who need the full arc — from an unclear problem, through research and flows, to a designed interface and a design system — done by people who will make sure it is actually buildable and shipped, not left as a beautiful file nobody can implement.

What you get

  • User research sized to the decision at hand — interviews, observation, review of your support tickets and analytics — so the design answers a real problem rather than an assumed one
  • Information architecture and user flows that map the whole journey, including the empty, loading, error and edge states that get skipped and then cause the most pain in build
  • Wireframes and interactive prototypes you can put in front of real users and click through, so decisions are tested cheaply before they become expensive code
  • Visual and interface design — the actual screens — designed against real content and real data, not lorem ipsum and best-case placeholders
  • A design system: reusable components, tokens, states and usage rules, built to line up with how the front end is actually engineered so it stays true instead of drifting
  • Accessibility built in to WCAG from the first wireframe — keyboard paths, focus order, contrast, semantics and screen-reader behaviour — not bolted on as a late audit
  • A design-to-code handover engineers can build from without guessing: specs, states, edge cases and the reasoning behind decisions, delivered alongside the people who wrote it

What UI/UX & Product Design does for you

  • Design cuts build risk instead of adding cost

    The most expensive thing in software is building the wrong thing and finding out after it ships. Research, flows and a tested prototype are the cheapest place to be wrong — a prototype is hours to change, a built feature is weeks. Skipping design to “just build it” does not save time; it moves the discovery of the real requirement to the most costly possible moment and pays for it in rework.

  • Designs that ship, because they were designed to be built

    A mockup that ignores loading, error and empty states, or asks for interactions that are ruinous to build, gets quietly reinterpreted by whoever implements it under pressure — and the shipped product no longer matches the approved design. Because our designers work with our engineers throughout, what we hand over is buildable, so the thing users get is the thing that was designed.

  • Outcomes you can measure, not taste you have to trust

    We tie the work to things the business can see move: task completion, conversion, drop-off, time-on-task and support-ticket volume. That makes design a decision you can evaluate rather than a matter of whose eye you trust, and it means when we disagree we can settle it with users rather than with seniority.

Why teams choose us for UI/UX & Product Design

  • Our designers and engineers are the same delivery team, so a design is pressure-tested against what it costs to build while it is still cheap to change — not discovered to be impractical after sign-off.
  • We treat design as problem-solving measured by outcomes, not by the designer’s preferences, and we will happily be proven wrong by a usability test rather than defend a decision on taste.
  • Senior people do the work. The person who runs your research and shapes your flows is the person who designs the screens — you are not sold a lead in the pitch and handed a junior for delivery.
  • Accessibility is part of how we design from the first wireframe, so it widens who can use your product and lowers your legal exposure, rather than becoming a costly remediation project later.

What UI/UX & Product Design includes

The concrete pieces of work this covers — scoped to what your problem actually needs.

  • User research and discovery

    Interviews, contextual observation, and mining what you already have — support tickets, session recordings, analytics, sales objections — sized to the decision. Enough research to stop guessing, not a six-month study that delays the build and answers questions nobody was asking.

  • Information architecture and user flows

    How the product is structured and how someone actually moves through it to get a job done. We map the whole flow including the states that get skipped — empty, loading, error, permission-denied, first-run — because those are where real products break and where developers otherwise improvise.

  • Wireframing and interactive prototyping

    Low- and high-fidelity prototypes people can click through and react to. The point is to be wrong cheaply and early: a prototype resolves an argument about a flow in an afternoon, where the same argument settled in production code costs weeks and a grumpy engineering team.

  • Visual and interface design

    The screens themselves — layout, hierarchy, typography, colour and interaction — designed against real content and realistic data so the design survives contact with a long name, an empty list or a slow network, rather than only looking good in the pitch deck.

  • Design systems

    Reusable components, design tokens, documented states and usage rules, structured to match how your front end is actually built. A design system that mirrors the component model in code stays honest; one drawn in isolation drifts out of sync within a release or two and becomes a museum piece.

  • Usability testing and accessibility

    Moderated and unmoderated testing to see where real people stumble, and accessibility designed in to WCAG — keyboard operation, focus order, contrast, semantics and assistive-technology behaviour — verified with real tools rather than assumed from a checklist.

Where it fits

  • A new product that needs shaping before it is built

    You have a problem and a rough idea, but not a clear picture of the flows, the screens or the edges. We run the research, shape the information architecture and flows, and prototype and test the core journeys — so engineering starts from a validated design instead of building the first plausible idea and reworking it later.

  • An existing product where users keep getting stuck

    Conversion is leaking, support tickets cluster around the same screens, or a key task takes too long. We find where and why people stall through research and testing, redesign the problem journeys, and measure whether the fix actually moved the numbers rather than just changed the look.

  • A product whose interface has drifted into inconsistency

    Years of features shipped by different people have left mismatched patterns, duplicated components and an experience that feels stitched together. We build a design system grounded in your real front-end components, then bring the product into line with it so future work stays coherent instead of compounding the mess.

  • A design that keeps dying in handover

    You have had good-looking designs that the build never quite matched, because the mockups ignored edge cases or asked for the impractical. We redesign with engineering in the room and hand over specs, states and reasoning developers can build from directly, so the shipped product matches the intent.

How we approach UI/UX & Product Design

We start with the user’s problem and the outcome you need to move, then work outward from there — research to understand it, flows and wireframes to structure a solution, prototypes to test it, and interface design to resolve it into something real. Fidelity is added deliberately: we do not polish pixels on a flow that has not been validated, because making the wrong thing beautiful only makes it more expensive to throw away. Every step is aimed at being wrong as cheaply and as early as possible, so the costly parts of the build rest on decisions that have already survived contact with real users.

Throughout, our designers work with our engineers rather than in a separate phase before them. That collaboration is where designs become buildable: an engineer flagging that a particular interaction is trivial one way and punishing another, or that an edge case the design ignores will dominate the effort, is worth more at the wireframe stage than in a fraught handover meeting. The result is a design shaped by what it costs to build, so what ships is what was designed — not a compromise a developer reverse-engineered under deadline.

How we run a product-design engagement

We begin by getting concrete about the problem and how we will know we have solved it. That means understanding the users and their jobs, agreeing the outcomes the design is meant to move — task success, conversion, drop-off, ticket volume — and doing enough research to replace assumptions with observations. We size the research to the decision: sometimes that is a fortnight of interviews and analytics review, sometimes it is a focused week reading your existing support data, but it is never a study run for its own sake while the build waits.

From there we work up in fidelity, and we test as we go. Information architecture and user flows come first because they are the decisions everything else hangs off, then wireframes, then interactive prototypes we put in front of real users. We deliberately keep things rough until a flow is validated, because polishing an unproven journey wastes effort on something that may change. Engineers review the work as it develops, so buildability concerns surface while they are still cheap to act on rather than at handover.

Once the flows hold up, we resolve them into finished interface design against real content and data, extract the reusable parts into a design system, and complete the accessibility work. Handover is not a file drop: we deliver specifications, component states, edge cases and the reasoning behind decisions, and — because the same team builds it — the designers are there while it is implemented to answer questions and protect the intent. Then we watch the real numbers to confirm the design did what it was meant to.

How design connects to engineering and the design system

The gap where designs go to die is the handover. A design tool can express interactions and layouts that are cheap to draw and expensive or impossible to build, and it says nothing about the states — loading, empty, error, partial-permission, offline — that make up most of the real engineering. We close that gap by designing with the constraints of the build in view from the start, and by making the design system line up with the component model the front end actually uses. When a component in the design maps cleanly to a component in code, changes stay in sync and the system stays true; when they are drawn in separate worlds, they drift apart within a release or two.

A design system is the mechanism that keeps a product coherent as more people work on it, so we build it as shared infrastructure rather than a style guide. That means design tokens for colour, spacing, typography and the like defined once and consumed by both the designs and the code; components documented with every state they can be in, not just the happy path; and clear rules for when to use each pattern so the next feature reuses the system instead of quietly reinventing it. Structured this way, the system reduces build effort — engineers assemble known parts rather than bespoke every screen — and reduces the design effort of every future feature too.

On handover itself, we deliver what an engineer needs to build without guessing: precise specs, all component states, the edge cases named explicitly, and the intent behind the decisions so that when reality forces a small change, the developer changes it in the spirit of the design rather than against it. Because our designers and engineers are one team, that handover is a conversation that continues through implementation, not a document thrown over a wall and hoped upon. That is the difference between a design that ships intact and one that arrives on screen as a distant relative of what was approved.

Accessibility and inclusive design

Accessibility is not a compliance chore we bolt on at the end; it is part of designing a product that works for the people who need to use it, and it is far cheaper to build in than to retrofit. We design to WCAG from the first wireframe — sufficient colour contrast, a logical focus order, keyboard operation for everything, meaningful semantics and sensible labelling, and content that a screen reader can make sense of. Doing this early costs almost nothing; discovering at launch that a core flow is unusable without a mouse, or illegible to a screen reader, turns into an expensive remediation project and, increasingly, a legal one.

Inclusive design is broader than passing an audit. It means designing for the range of real people and real conditions: someone using the product one-handed on a train, a user with low vision relying on larger text, a person who cannot perceive colour as the only signal, someone on a slow connection where the loading state is most of their experience. Designing for those cases tends to make the product clearer for everyone — the same discipline that helps a screen-reader user also produces a cleaner, more legible interface for the majority.

We verify rather than assume. Automated checkers catch the obvious failures, but a page can pass every linter and still be miserable to use with a keyboard or a screen reader, so we test with the actual assistive technology and real interaction. Where you have a specific conformance target — a public-sector requirement, a procurement condition, a stated WCAG level — we scope to it explicitly and tell you plainly what meeting it does and does not involve.

Signs it’s time

  • You are about to build a product and want to be sure you are building the right thing, before it becomes expensive code rather than a cheap prototype
  • Users keep getting stuck in the same places — conversion is leaking or support tickets cluster around particular screens — and you need to know why, not just guess
  • Your interface has drifted into inconsistency as different people shipped different patterns, and you need a design system to bring it back into line
  • Good-looking designs keep arriving on screen as something worse, because the mockups ignored the edge cases and the reality of the build

How we work and hand over

We work in the open and in short cycles, and we favour evidence over opinion. You see the work as it develops — flows, wireframes, prototypes in a state you can actually click — rather than a single reveal at the end, so feedback lands while it is still cheap to act on. When there is a genuine disagreement about a design, our instinct is to resolve it with a usability test or a look at the data rather than by whoever is most senior in the room, because the user’s behaviour is a better arbiter than any of our tastes.

Handover is a deliverable in its own right, not a courtesy at the end. You get the design files, the design system, the specifications and the reasoning, all in your own tools and accounts, and — because the same team builds what it designs — the designers stay involved through implementation to protect the intent and answer the questions a static spec never anticipates. Nothing about the way we hand over is engineered to keep you dependent on us; if you take the whole thing to another team, everything they need to build and extend it is there.

    Runbooks & SLOs

What changes

  • The right thing, found early

    Research and tested prototypes settle what to build while it is still cheap to change, so engineering is spent on a validated design rather than on discovering the requirement in production.

  • Designs that survive the build

    Because designers work with engineers throughout, what ships matches what was designed — edge cases and buildability handled up front instead of improvised under deadline.

  • Measurable improvement

    Task success, conversion, drop-off and support-ticket volume tracked against the design, so you can see it worked rather than take it on faith.

Industries we serve

Domain knowledge changes what gets built. A few of the sectors we know before the first meeting.

How pricing works

  • The dominant driver is how much of the arc you need. Full end-to-end product design — research through flows, prototyping, interface and a design system — is a different scale of work from a focused redesign of a couple of problem journeys, and we cost the parts you actually need rather than a fixed package.
  • The depth of research and testing moves the figure. A product aimed at a niche professional audience where a wrong assumption is costly justifies more discovery than a straightforward internal tool, and we size that deliberately instead of defaulting to either extreme.
  • Building a design system is an investment that pays back over every future feature, so we cost it as foundational work rather than folding it into a single screen’s budget — and we will tell you honestly when your product is too small or too early to need one yet.
  • The state of what exists matters: designing into a coherent product is quicker than untangling years of inconsistent patterns first, and we would rather scope that reality honestly up front than discover it halfway through.

Typical timeline

  1. 01

    Discovery and research

    We pin down the users, their jobs and the outcomes the design must move, then run research sized to the decision — replacing assumptions with observations before anything is drawn.

  2. 02

    Flows and prototypes

    Information architecture, user flows and wireframes come first, then interactive prototypes tested with real users — kept deliberately rough until the journey is validated.

  3. 03

    Interface and design system

    Validated flows are resolved into finished interface design against real content, the reusable parts extracted into a design system, and accessibility completed.

  4. 04

    Handover and build support

    Specs, states, edge cases and reasoning handed over, with the designers involved through implementation to protect the intent — then we check the real numbers moved.

Why teams choose us for UI/UX & Product Design

  • We operate what we build

    Designers and engineers on the same delivery team means designs are shaped by what it costs to build them, so they ship intact rather than being quietly reinterpreted in handover.

  • Outcomes over taste

    We measure design against the user’s problem and numbers the business can see move, and we settle disagreements with usability tests rather than with whose eye is most senior.

  • Senior people, no bait-and-switch

    The person who runs your research and shapes your flows is the person who designs your screens — you are not sold a lead in the pitch and handed a junior for the work.

  • Honest about scope

    If you need one slice rather than the whole arc, or your product is too early for a design system, we will say so and point you at the smaller, cheaper option rather than upselling process.

Common questions

How is this different from your UX Design, UI Design and Web Design services?

This is the broad, end-to-end offering: research, information architecture, flows, prototyping, interface design, design systems, usability testing and accessibility, run as one continuous piece of work. The narrower services are for when you need a single slice — UX Design for the research-and-flows work, UI Design for the visual and interface layer, Web Design specifically for websites. If you only need one of those, that is the honest and cheaper answer, and we will tell you so during scoping rather than selling you the whole arc.

Can we skip the design phase and just start building to save time and money?

You can, but it rarely saves either. Skipping design does not remove the moment where you discover the real requirement — it just moves it to the most expensive possible place, which is built code rather than a prototype. A prototype is hours to change; a shipped feature is weeks, plus the engineering morale of building the same thing twice. Design earns its keep by finding the wrong turns while they are still cheap to correct. For genuinely tiny or throwaway work we will tell you design is not worth it — but for anything you intend to keep, it reduces total cost rather than adding to it.

How do you stop the design from being watered down or ignored when it gets built?

By not treating build as a separate phase. Our designers work with our engineers from the start, so buildability concerns surface at the wireframe stage where they are cheap to resolve, and the design we hand over is already shaped by what it costs to build. Handover includes the specs, every component state, the edge cases and the reasoning — and because the same team implements it, the designers stay involved through the build to protect the intent. That is the difference between a design that ships intact and a mockup a developer reinterprets under deadline.

Do we need a design system, and when is it worth building one?

Not always. A design system is infrastructure that keeps a product coherent as more people work on it and pays back over every future feature — so it is worth it when your product is growing, when several people are shipping into it, or when inconsistency is already causing friction. For a small, early or single-purpose product, a full system is premature and we will tell you to hold off. When it is worth building, we structure it to line up with your real front-end components so it stays in sync with the code rather than drifting into a decorative style guide nobody follows.

How do you measure whether the design actually worked?

We agree at the start what the design is meant to move — task completion, conversion, drop-off, time-on-task, support-ticket volume for the affected journeys — and we tie the work to those. Usability testing tells us where people stumble before launch; the real numbers tell us afterwards whether the change did what it was meant to. This is deliberate: it makes design a decision you can evaluate rather than a matter of trusting someone’s eye, and it means when we disagree during the work we can settle it with users rather than with opinion.
