Front-end Development

Interfaces that stay fast as they grow

We build front-ends for complex products, where choices about architecture, state, and rendering decide how fast your team can keep shipping. From prototype to performance tuning.

We start with your problem, not the framework, the sluggish UI, the unmaintainable component sprawl, the redesign that stalled, and tell you honestly what it takes to fix it.

Front-end development services

Built for complex projects, from prototyping to performance work. Pick a capability to see how we approach it.

Legacy code becomes a liability that slows every new feature, and rewriting a massive jQuery or AngularJS monolith from scratch is rarely a sound business move. We refactor monolithic front-ends into modern, component-based architectures incrementally, part of our broader software development work, so you keep shipping value while paying down technical debt.

How we help

Our teams rely on the strangler-fig pattern to migrate applications to React, Vue, or Angular piece by piece. We introduce build tools such as Vite and Webpack, enforce strict typing with TypeScript, and set up CI/CD pipelines. You end up with a modernized codebase that’s testable and extensible, with none of the big-bang rewrite risk.

Scaling a complex front-end on a single monolithic codebase eventually creates gridlock, where engineers end up blocking one another. We decouple the application into independently deployable domains to restore development velocity for your teams.

How we help

We use module federation to stitch distinct features together at runtime, so teams can deploy updates without waiting on anyone else. We set governance models for shared dependencies to prevent bundle bloat while keeping the experience cohesive. The result is a unified interface that feels like one product to users but deploys like a collection of microservices.

Teams shouldn’t be rebuilding buttons and form inputs for every new feature, and inconsistent UI is a clear symptom of wasted engineering hours. We build reusable component libraries that enforce design consistency and speed up development right across your organisation.

How we help

Our engineers create documented component libraries in Storybook, backed by strict versioning and governance, with theming tokens and accessibility primitives set at the root level. So your developers can stop debating pixels and start shipping features by assembling pre-validated, dependable building blocks instead.

The old trade-off between search-engine optimization and interactivity is a thing of the past. Traditional single-page apps sacrifice rankings and initial load speed for interactivity; we build hybrid applications on frameworks such as Next.js that deliver the best of both worlds.

How we help

We architect solutions with server-side rendering for instant first paint and SEO, then hydrate into a fully interactive application on the client. We add incremental static regeneration to serve dynamic content at static speeds. So you get an application that ranks well on Google and still feels instant to the user.

Complex apps fall apart when data flow turns unpredictable. As features multiply, managing state across hundreds of components breeds bugs that are nearly impossible to reproduce. We put in robust state-management architectures that keep data consistent without a performance penalty.

How we help

We select the right pattern for the job, whether that’s Redux for global transactional state, TanStack Query for server-state synchronization, or atomic state for high-performance UI updates. We separate business logic from UI components to make the application testable, predictable, and easier to refactor as requirements evolve.

Performance is a feature, not an afterthought, slow-loading pages drive users away and drag down search rankings. We optimize front-end performance by analysing the critical rendering path, removing render-blocking resources, and putting aggressive caching strategies in place.

How we help

Our engineers profile applications with Lighthouse and WebPageTest to target Core Web Vitals. LCP, CLS, and INP. We implement code splitting, lazy loading, and image optimization pipelines, and we trim JavaScript execution time to improve Time to Interactive. So your application performs on low-end devices, not just developer workstations.

Manual testing is the bottleneck that quietly kills release velocity, if you depend on people to click through every screen before a deploy, you simply can’t keep shipping fast. We build automated testing pipelines that catch regressions before they merge, not after they launch.

How we help

We build end-to-end testing suites in Playwright or Cypress that simulate real user workflows, and we add visual regression testing to catch the pixel-level layout shifts unit tests miss. This shifts quality left, giving your developers the confidence to deploy to production even during high-risk windows.

Building without validation leads to costly rework down the line. We validate workflows before a single line of code is written, creating interactive prototypes and running usability testing so engineering effort stays focused on the right problems.

How we help

Our designers use Figma to create high-fidelity mockups and documented developer handoffs. We run user research and analyse session data to iterate on the designs as we go. You end up with a user interface grounded in actual user behaviour, not assumptions.

The stack we build with

We build on the framework that fits your product and team, not the one making noise this quarter. The goal is an architecture your engineers can extend and maintain for years.

React
Vue
Angular
Svelte
Next.js
Nuxt.js
Gatsby
Ember.js

We set up fast, modern build tooling so local dev stays quick and production bundles stay lean, with config kept sensible enough that new engineers pick it up without a manual.

Webpack
Vite
Rollup
Parcel
esbuild
Babel
PostCSS

We fit the state approach to the problem, global, server, or local, so data stays consistent without dragging the UI down.

Redux
MobX
Zustand
Recoil
Vuex
Pinia
NgRx
Context API

We test at the levels that catch real regressions, unit, integration, end to end, wired into CI so nothing broken gets merged.

Jest
React Testing Library
Cypress
Playwright
Vitest
Enzyme
Jasmine

We watch Core Web Vitals and real-user metrics in production, so slowdowns and errors surface before a customer ever feels them.

Lighthouse
WebPageTest
New Relic
Datadog
Sentry

Hotjar

We build on accessible, well-maintained component foundations, or your own design system, for consistency without reinventing the primitives.

Abstract

Our front-end development process

Eleven steps, run in order, step through the sequence from first review to production.

01

Brief & design review

We agree user flows, performance targets, and accessibility standards with your stakeholders, and pin down the target browsers, devices, and constraints before anything else.

02

Prototype & validate

We build interactive prototypes in Figma or Adobe XD and put them in front of real users before a line of code, which heads off expensive late-stage changes.

03

Component blueprint

We define component hierarchies, naming, and reusable patterns as the foundation for maintainable code, with colour, type, and spacing tokens holding it consistent.

04

Environment setup

We set up build tools, linters, formatters, and test frameworks so quality is enforced from the first commit and holds consistent across the team.

05

Component build

We build the UI in increments, from buttons and forms up to complex features, each shipping with unit tests, accessibility, and documentation.

06

Responsive layout

We build mobile-first layouts on Grid, Flexbox, and media queries that adapt across screen sizes, tested on real devices rather than emulators.

07

Data & state wiring

We wire the interface to your APIs with proven fetching, caching, and error patterns, keeping state consistent across components as it grows.

08

Speed tuning

We profile with Lighthouse and DevTools, then apply code splitting, lazy loading, and caching to clear the rendering and network bottlenecks.

09

Cross-browser checks

We test across Chrome, Firefox, Safari, and Edge on BrowserStack, leaning on polyfills and progressive enhancement so core features work everywhere.

10

Accessibility audit

We check keyboard nav, screen-reader support, contrast, and semantics against WCAG 2.1 AA through a mix of automated and manual testing.

11

Ship & monitor

We deploy through CI/CD with staging and rollback in place, then watch performance metrics and error rates once it's live.
