The problem

Design problems that cost you users

Design requests reach us in two forms. One is a new product with nothing but a list of features, where someone has to decide what the first screen is and what happens after the user taps the main button. The other is an existing site or application that works but frustrates people: a checkout with too many steps, an admin panel only its author understands, a website that looks ten years older than the business.

We should be clear about what we are. We are a development company with designers on staff, and we design the software and websites we build. We do not sell logo packages or advertising campaigns. What you get in exchange is design checked by the people who must build it. Our team has developed 100+ mobile apps alongside its web work, and we have seen how often an attractive mockup falls apart at the first real data.

  • Mockups that could not be built

    A freelance designer delivered beautiful screens. Then the developers found states nobody drew: empty lists, long names, error messages, tablet widths. The live product looks like a rough copy.

  • Every screen looks slightly different

    Three shades of blue, five button styles and spacing that changes from page to page. Each new feature adds another variation because there is no shared set of components to draw from.

  • Users cannot find the main action

    Support keeps answering the same how-do-I questions. Analytics shows people leaving at the same step. The feature exists, but the path to it is hidden behind menus and jargon.

  • A redesign that risks what works

    The site needs a refresh, but it also ranks well and converts. You worry that a new look will break familiar paths, lose search positions or confuse returning customers.

What we do

Design work we do in house

Design at WorldWin Coder is a phase of the build, done by designers who sit in the same project as the developers and QA. It covers the thinking before the pixels and the specifications after them.

Research and discovery

Interviews with real users and staff, a review of analytics and support tickets, and a look at competing products, summarized into the few findings that should change the design.

User flows and structure

Diagrams of how each type of user gets from arrival to done, plus a sitemap or screen inventory, agreed before anyone argues about colors.

Wireframes

Low-detail layouts for every key screen and its states, quick to change, used to settle content, hierarchy and menus while changes are still cheap.

Visual design and design systems

Type, color, spacing and a library of reusable components with their variants, documented so new screens can be assembled consistently by anyone on the team.

Interactive prototypes

A clickable model of the main paths that looks real enough to test with users and stakeholders, on a phone or a laptop, before development starts.

Accessibility and handoff

Contrast, focus order, target sizes and labels reviewed against WCAG 2.2 AA when you ask for it, then specs, tokens and assets passed to developers in a form they can use directly.

Typical projects

Design engagements we run

01

Design for a new application

Flows, wireframes, a component library and final screens for a web or mobile product, produced as the first phase of a build we then develop.

02

Website redesign

A new structure and look for a marketing or content site, planned around the pages that already bring traffic, and built as a custom theme afterwards.

03

UX review of an existing product

A walk through the main tasks with fresh eyes and real users, ending in a ranked list of fixes, from quick wording changes to screens worth rethinking.

04

A design system for a growing product

An audit of the interface as it stands, then one consolidated set of tokens and components, rolled out screen by screen so the product converges on a single style.

In depth

From research to a buildable design

Research sized to the decision

Research does not have to be a three-month study. For most projects, five or six conversations with people who do the task, plus an hour in the analytics and the support inbox, reveal the same handful of problems. We write those up as findings with evidence, then turn them into the flows: the steps a buyer, a learner or an administrator takes from start to finish. A flow diagram is the cheapest design artifact there is, and it catches missing screens before anyone has drawn one.

Wireframes carry the arguments

Disagreements about what belongs on a page are best had in gray boxes. Wireframes let you and your team decide priority, wording and layout without being distracted by a photo or a shade of green. We wireframe the awkward states on purpose: the dashboard with no data yet, the table with four hundred rows, the form after a failed payment, the same screen on a narrow phone. Those are the states that make or break a build estimate.

A design system, at the right size

A design system is a set of decisions made once: colors and type as named tokens, then buttons, inputs, cards, tables and modals with every variant drawn. A small product needs a small one. Its value shows up later, when a new screen takes hours instead of days and looks like it belongs. We name tokens and components the same way in the design file and in code, which matters whether the front end is a custom WordPress theme, a set of React or Vue components or widgets in a Flutter app.

Accessibility and handoff

Contrast, text size, tap targets, visible focus and form labels are design decisions long before they are code, and fixing them in a mockup costs minutes. When a project has an accessibility requirement we design and test to WCAG 2.2 AA and state exactly what was checked. We do not issue compliance certificates. Handoff is a conversation that starts early, because the developers are colleagues: one of them reviews the wireframes for feasibility and cost, and the designer later checks each built screen on staging against the design.

Redesigning something that is live

An existing product has habits and data attached. Before changing it we record what performs: the pages that rank, the paths that convert, the screens regular users open many times a day. Those are kept recognizable or changed deliberately. Large applications are redesigned in slices, one area per release, so users are not handed a strange new interface on a Monday morning.

Process

Stages of a design project

  1. 1

    Brief and research

    We learn the goals, the users and the constraints, review any existing product and data, and agree what success would look like.

  2. 2

    Flows and wireframes

    User flows and a screen inventory come first, then wireframes for every key screen and state, reviewed with you in short rounds.

  3. 3

    Visual direction

    Two or three key screens are designed in full to settle the look. Once approved, that direction becomes the base of the component library.

  4. 4

    Prototype and test

    A clickable prototype is put in front of real users or your team. What confuses them is fixed before a line of code is written.

  5. 5

    Handoff and build review

    Developers receive specs, tokens and assets. The designer stays on the project and reviews each built screen on staging.

FAQ

Before you brief a designer

Do you take design-only projects?
Mostly no. Our designers work on websites, applications and apps that our developers build, and that is where we do our best work. We do take standalone UX reviews and redesign plans for existing products, on the understanding that you may build the result with us or with your own team.
What do we receive at the end of the design phase?
You receive the editable design files, the flows, wireframes, final screens for desktop and mobile, a component library with tokens, and a clickable prototype. The files are yours, in the same way the source code is, and any competent team could build from them.
Can you redesign our product without rebuilding it?
Often, yes. If the code is reasonably structured, a new interface can be applied to the existing back end screen by screen. We review the front-end code first and tell you whether a reskin is realistic or whether the templates need rebuilding to carry the new design.
Will the design be accessible?
We apply accessible defaults on every project: sufficient contrast, readable type, visible focus and labeled controls. When you need a formal target we design and test to WCAG 2.2 AA and document the checks. A full conformance claim also depends on content and code, so we do not label a design as certified.
Can you design a theme for our LMS or learning portal?
Yes. Learner dashboards, course pages and quiz screens are familiar ground for us, on WordPress LMS plugins and on Moodle. For Moodle the design is built as a custom theme, as explained on our Moodle theme development page.
How many revision rounds are included?
Rounds are agreed in the quote, and they are attached to stages: flows, wireframes, visual direction, final screens. Feedback is cheapest at the wireframe stage, so we push for decisions there. Changes after sign-off are still possible and are sized as change requests so the cost is clear.
What makes a design phase larger or smaller?
The count of unique screens and user roles matters most, followed by whether research is needed and how many platforms are covered. A marketing site with a dozen templates is a small job. A multi-role application with web and mobile versions needs a design system and more time.
