Web Development
Frontend development services
The interface is the product, as far as your users are concerned. We build front ends that respond quickly, work with a keyboard and don’t collapse under their own weight after a year.
Modern JavaScript makes it easy to ship far more code than a page needs. A heavy bundle may feel fine on a developer’s laptop, then crawl on a mid-range phone on a train. Interaction to Next Paint, one of Google’s Core Web Vitals, measures exactly this sort of sluggishness, and most users simply experience it as a site that feels broken.
We start by working out how much JavaScript a screen needs. Plenty of pages are better rendered on the server with small interactive parts added on top. Complex tools such as dashboards, editors and multi-step forms deserve a proper component architecture, typed with TypeScript and backed by tests. Picking the right approach for each part of a product saves more money than any later optimisation.
Accessibility isn’t a final-week task
Keyboard support, focus management and screen-reader labelling are much easier to build in than to retrofit, and custom components such as menus and dialogs are where accessibility most often goes wrong. We use WCAG 2.2 AA as our working target. For public-sector clients in the UK this can be a legal requirement, and for everybody else it’s a larger audience.
Common frontend problems
Sluggish interfaces
Too much JavaScript on load, unnecessary re-renders and third-party scripts blocking the main thread.
An inconsistent UI
Six kinds of button, no shared components, and every new feature reinventing the last.
An ageing framework
AngularJS, jQuery or an old React setup that nobody wants to work on and is getting harder to hire for.
