Frontend Development in Derry
The part your Derry customers actually touch — built to be fast on a mid-range phone, usable with a keyboard or a screen reader, and faithful to the design rather than approximately like it. Often the piece a business brings in separately, because their back end works and the interface is what is letting them down.
Why this comes up
The problem
Interfaces built without performance or accessibility in mind exclude a measurable share of users and get penalised in search. Both are far cheaper to build in than to retrofit once the component library has set.
What you get
What we deliver
- Component library built from your design system, so screens stay consistent as they multiply
- Core Web Vitals targets met and tested on throttled mobile, not on a fast desktop
- WCAG 2.2 AA — keyboard navigation, focus order, contrast and screen reader labelling
- Responsive layouts verified on real devices rather than a browser resize
- Integration against your existing API, with loading and error states designed rather than defaulted
- Component documentation your team can work from without reverse-engineering the code

Frontend Development in Derry — common questions
- Can you work with our existing back end?
- Yes, and it is a common arrangement. We build against your API as it stands. Where an endpoint makes the interface slow or awkward we will say so and suggest a change, but we will not require one to start.
- Why does accessibility matter commercially?
- Roughly one in five people in the UK has a disability, so an inaccessible interface excludes real customers. Public sector contracts require it outright, and the same work — proper headings, labels, contrast — tends to improve the experience for everyone.
- Our site is slow. Is a rebuild the only fix?
- Rarely. Most slowness comes from oversized images, blocking scripts and third-party tags rather than the framework. An audit is cheap and usually identifies changes worth more than a rebuild would cost.
- Will it match our designs exactly?
- Yes, and where a design will not survive contact with real content or a narrow screen, we raise it during the build rather than quietly approximating it and hoping nobody compares.
- Do you work with businesses across County Londonderry?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Northern Ireland, including Derry and the surrounding County Londonderry area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Derry businesses do you usually work with?
- Cross-border trading systems for businesses working into Donegal, and manufacturing tooling for the north west. Beyond that we work across Manufacturing, Healthcare, Higher Education, Digital and Tourism.
- Do you cover the areas around Derry?
- Yes — we work throughout Northern Ireland, including Belfast, Lisburn. Derry is an urban area of roughly 85,000+, and we take on work across the wider County Londonderry region rather than the city boundary alone.
