Service 04 / 11

Maintainable, accessible React component systems and product UIs that your team can extend for years — not a tangle of one-off screens.

ReactTypeScriptStorybook

Overview

What you get.

  • Reusable systems
  • Type safe
  • Accessible

Good React is mostly about boundaries: small composable components, predictable state and a clear data layer. We design those boundaries first, so features stay cheap to add as the product grows.

We build with strict TypeScript, document components in Storybook and cover behaviour with tests, so design and engineering share one source of truth.

Most React projects slow down not because React is slow, but because component boundaries were never designed. Props balloon, state leaks across screens and every change risks breaking something unrelated. We invest early in the structure that prevents this.

Whether you need a new product UI, a shared component library across several apps, or a careful rescue of an inherited codebase, we work in small, reviewable increments with tests so you can see progress and risk at every step.

Why it matters

The problem we solve.

01

UI inconsistency compounds

Without a shared component layer every screen reinvents buttons, spacing and states — slowing teams and confusing users.

02

Accessibility is not optional

Accessible interfaces reach more customers, reduce legal exposure and tend to be better for everyone.

03

Velocity depends on structure

Well-factored components and types let new engineers ship safely in days rather than weeks.

04

Rewrites are expensive

Incremental modernisation delivers value continuously instead of freezing the roadmap for a big-bang rewrite.

Scope of work

What’s included.

01

Component library

Reusable, themeable, accessible primitives documented in Storybook.

02

Design system implementation

Figma tokens mapped to code with variants, states and dark mode.

03

State & data management

TanStack Query, Zustand or Redux Toolkit — chosen for the problem, not by habit.

04

Forms & validation

React Hook Form with schema validation (Zod) and accessible error handling.

05

Accessibility (WCAG 2.2 AA)

Keyboard navigation, focus management, ARIA and screen-reader testing.

06

Legacy modernisation

Class components, jQuery and old SPAs refactored to modern React incrementally.

Ideal clients

Who this is for.

01

Product teams

Companies building a web app that needs a scalable, consistent UI layer.

02

Multi-product organisations

Groups that need one design system powering several apps and brands.

03

Startups scaling their frontend

Teams whose early prototype is starting to slow every release.

04

Teams with legacy code

Projects stuck on class components, jQuery or outdated tooling.

How the project runs

Our process.

Transparent milestones, weekly demos and one point of contact from kickoff to launch.

  1. 01

    UI audit

    Inventory of screens, patterns and inconsistencies to define the component taxonomy.

  2. 02

    Design tokens & primitives

    Colour, type and spacing tokens, then atomic components (buttons, inputs, modals).

  3. 03

    Composition

    Patterns and feature components assembled from primitives, with isolated stories.

  4. 04

    State & data layer

    Server state, client state and URL state separated and typed end to end.

  5. 05

    Testing

    React Testing Library, visual regression and a11y checks in CI.

  6. 06

    Documentation & handover

    Storybook, contribution guide and a walkthrough for your team.

Quality bar

Standards we hold.

01

Typed from end to end

Strict TypeScript, typed props and validated API responses.

02

Tested behaviour

Tests focus on what users do, not implementation details, so refactors stay safe.

03

Accessible primitives

Keyboard support, focus handling and ARIA patterns baked into every base component.

04

Documented in isolation

Every component has stories showing variants, states and edge cases.

Glossary

Terms we use.

Component composition
Building complex UI by combining small, focused components.
Virtual DOM / reconciliation
React's diffing mechanism that updates only what changed.
Memoisation
Caching a computed result (useMemo, React.memo) to avoid needless re-renders.
Controlled component
A form input whose value is owned by React state.
Storybook
A workshop for building and documenting UI components in isolation.
Code splitting
Loading JavaScript on demand to keep initial bundles small.
Hooks
Functions like useState and useEffect that let function components manage state and side effects.
Prop drilling
Passing data through many component layers just to reach a deep child — usually a sign to restructure.

FAQ

Common questions.

Can you join an existing React codebase?

Yes. We start with a short code audit, agree conventions, then ship alongside your team.

Do you build design systems too?

Yes — from tokens in Figma to a published, versioned component package.

Which state library do you recommend?

Server state in TanStack Query, minimal local state, and a store only when truly shared. We avoid global state by default.

Do you work with our designers?

Yes. We map Figma variables and components directly into code so designers and engineers stay in sync.

How do you keep bundle size down?

Route-level code splitting, lazy loading heavy widgets, avoiding oversized libraries and monitoring bundle analysis in CI.

Can you help us choose between Vite, Next.js and others?

Absolutely. We recommend based on SEO needs, hosting and team skills, and explain the trade-offs plainly.

Working together

How we engage.

01

Fixed-scope project

A defined scope, timeline and price agreed after discovery. Best for launches and rebuilds with clear requirements.

02

Monthly retainer

A dedicated block of senior time each month for continuous delivery, iteration and support.

03

Audit & advisory

A short, focused engagement that reviews what you have and hands you a prioritised plan to act on.

What to expect

01

Kickoff

A 45–60 minute call to understand goals, audience, constraints and timeline.

02

Written proposal

Scope, milestones, deliverables and pricing within a few working days of the call.

03

Weekly rhythm

A short demo and written update every week so there are never surprises.

04

Your input

One decision-maker, timely feedback and access to brand assets, content and accounts.
