Frontend Development
Responsive, accessible, high-performance interfaces built with modern component architecture.
01Overview
We build frontends that hold up under real conditions: fast to load, accessible by default, and structured so they remain maintainable as features grow. Components are typed, tested where it matters, and assembled into a coherent system rather than one-off pages.
02How we approach it
Frontend work starts before any component is written. In Discover we establish what the interface actually has to do: the content it must carry, the devices and connection speeds it will meet, and the accessibility requirements that apply. Define then fixes the technical ground rules — the rendering approach, the component inventory, and a performance budget the build is measured against from the first commit.
If a design system already exists, we implement it without dilution: spacing, type, and interaction behaviour arrive in the browser as designed. If it doesn't, design and engineering are developed together so tokens and components are shared rather than translated. Either way, the Engineer stage produces typed, documented components that behave consistently across the whole interface — server-rendered by default, with client-side JavaScript added only where interaction genuinely requires it.
Validate tests the interface against what Define agreed. We check the build on real devices and across viewport sizes, verify accessibility to WCAG 2.2 AA — keyboard navigation, screen reader behaviour, contrast — and run it against the performance budget under realistic conditions. Failures are fixed before Deploy, not recorded for later. The result is a release that has already met its standards, rather than one scheduled to meet them eventually.
Release goes through staged deployment: the build is exercised in a controlled environment before it reaches production, with error monitoring live before real traffic arrives. From there the system moves into Evolve. Because the component system is typed, documented, and version-controlled, new sections and features extend what exists instead of accumulating alongside it — which is the difference between a frontend that ages and one that degrades.

07Common questions
What determines the cost of a frontend build?
Mostly scope: the number of distinct templates and components, the complexity of interaction and state, the strictness of the performance and accessibility targets, and whether we are implementing an existing design system or defining one alongside the build. We don't publish prices because those variables move cost significantly. After you send a brief through the contact form, we set out scope, cost, and approach in a written proposal.
We already have designs. Can you build directly from them?
Yes — implementing an existing design system is one of the most common shapes this work takes. We audit the designs during Discover, and in Define we flag anything the build will need that the files don't yet cover: loading and error states, breakpoint behaviour, keyboard focus, content that runs longer than the mock-ups. That review protects the design rather than second-guessing it — the aim is that what ships matches what was signed off.
Can the frontend connect to our existing backend or CMS?
It can. We build against whatever serves your data — an existing API, a headless CMS, or a backend another team maintains. The interface consumes it through typed contracts, so the shape of every request and response is explicit and mismatches surface at build time rather than in production. If the existing API needs changes to support the interface properly, we identify them during Define so the work is agreed before engineering starts.
What happens at handover, and who owns the code?
Handover includes the version-controlled codebase, documentation, and a walkthrough for whoever maintains it next — your in-house team or ours. Because components are typed and documented as they are built, the codebase stays legible to people who didn't write it. Ownership, deliverables, and any ongoing service commitments are defined in the written engagement agreement each project signs, so both sides know what transfers and when.
How do you measure whether the frontend is actually fast?
Against a budget agreed before the build starts, not a feeling after it ends. During Validate we test the interface in the lab against Core Web Vitals and the specific budget set in Define; after Deploy, monitoring tracks how it performs for real users on real devices. If a later change threatens the budget, that shows up in measurement rather than in complaints. Speed is treated as a requirement the build must meet, not a property we hope it acquires.
