Frameworks

Frontend Frameworks We Build In

We work with the major frontend ecosystems and help you choose the right framework for your product type, team size, and performance requirements.

⚛️

React

The most-used frontend library — ideal for complex SPAs, large team codebases, and products needing a rich ecosystem of libraries and tooling. We use React with TypeScript, hooks architecture, and modern state management.

🟢

Next.js

React with built-in SSR, SSG, and ISR — the go-to for SEO-critical applications, marketing sites with dynamic content, and full-stack web apps that need fast initial page loads and great Core Web Vitals scores.

💚

Vue.js

Gentle learning curve, excellent two-way binding, and a clean component model. Vue 3 with Composition API is an excellent choice for teams coming from backend backgrounds or products that need fast onboarding for new developers.

Angular

A full-featured, opinionated framework best suited to large enterprise applications with complex forms, strict TypeScript enforcement, and teams that benefit from strong architectural conventions. Excellent for long-lived products.

What We Build on the Frontend

Single Page Applications (SPAs)

Rich, app-like experiences that update dynamically without full page reloads — for dashboards, SaaS tools, and web apps where fast interaction is critical.

Server-Side Rendered (SSR) Web Apps

Next.js and Nuxt apps with excellent Core Web Vitals, SEO-friendly HTML, and fast time-to-first-byte for content-heavy products and public-facing platforms.

Component Libraries & Design Systems

Reusable, documented component libraries in Storybook that standardise your UI, accelerate new feature development, and keep your product visually consistent at scale.

Micro-Frontend Architecture

Decompose large frontend monoliths into independently deployable modules — allowing multiple teams to own different parts of the UI without stepping on each other.

Progressive Web Apps (PWAs)

Web apps that work offline, install like native apps, and send push notifications — bridging the gap between web reach and mobile-app capability without maintaining two codebases.

Performance Standards

We Don't Ship Slow Frontends

Performance is a feature. A 1-second delay in load time reduces conversions by up to 7%. Every frontend we build is optimised for Core Web Vitals from the first sprint.

<2s First Load

Code splitting, lazy loading, and asset optimisation keep initial bundle size minimal. Users see content within 2 seconds on average connections.

Mobile-First Always

Every layout is designed and tested for mobile before desktop. Touch targets, font sizes, and interaction patterns are optimised for the majority of users on small screens.

WCAG 2.1 AA Accessible

Semantic HTML, proper ARIA roles, keyboard navigation, focus management, and sufficient colour contrast. Accessibility is built in — not bolted on after an audit.

SEO-Optimised Output

Server-side rendering, structured data, canonical tags, Open Graph metadata, and crawlable navigation — so search engines can index every page correctly from day one.

FAQ

Frontend Development FAQs

Common questions from product managers and CTOs starting a new frontend project.

Talk to a Frontend Engineer

The best framework depends on your context: React / Next.js is the safest general choice — largest ecosystem, most available talent, and works for nearly any product type. Vue 3 is excellent when team onboarding speed matters or you have developers more comfortable with HTML-first thinking. Angular excels for large enterprise apps with many developers that benefit from strict architectural conventions and built-in tooling. We'll recommend the right fit after understanding your team composition, product complexity, and long-term roadmap.

Yes — TypeScript is our default for all new frontend projects. The benefits compound over time: type errors caught at compile time rather than runtime, better IDE autocomplete and refactoring, self-documenting interfaces, and significantly reduced debugging time as the codebase grows. The productivity cost at the start is small; the maintainability gain at 12 months is substantial. We can work in plain JavaScript if your codebase requires it.

We follow a layered approach: local component state (useState) for UI-only state, server state handled by React Query or SWR (with automatic caching, background refetching, and optimistic updates), and global client state managed with Zustand or Redux Toolkit only when genuinely needed. This avoids the over-engineering trap of putting everything in a global store, keeps components simpler, and makes server-driven features much easier to build.

Yes — working on existing codebases is the majority of our frontend work. We begin with a code audit to understand your current architecture, identify technical debt hotspots, and plan how new features integrate cleanly. We adopt your code conventions, document our additions in the same style, and improve test coverage incrementally. Our goal is to leave your codebase easier to work in than we found it.

We use a testing pyramid approach: unit tests (Jest/Vitest) for pure functions and utilities, component tests (React Testing Library) for individual UI components in isolation, integration tests for multi-component flows with mocked APIs, and end-to-end tests (Playwright or Cypress) for critical user journeys run in CI on every PR. We prioritise test value over coverage percentages — testing behaviour, not implementation details.
