// Build — Frontend
React.js development for production-grade frontend systems
We build React applications that scale — typed, tested, performant, and structured so large teams can move fast without architectural debt. From SPAs to design systems and micro-frontend architectures.
// Capabilities
React engineering scope
Single Page Applications
Fast, component-driven SPAs with route-level code splitting, lazy loading, and optimistic UI patterns for real-time data products.
Component Libraries & Design Systems
Reusable component systems built with TypeScript, Storybook, and design tokens — shared across products and teams.
State Management
Choosing the right state approach per project: Zustand, Redux Toolkit, React Query, Context, or server state with SWR/TanStack Query.
Performance Engineering
Virtualised lists, memoisation strategy, bundle analysis, code splitting, and profiling with React DevTools to eliminate jank and unnecessary renders.
React + Backend Integration
Clean data-fetching layers with typed API clients, error boundaries, loading skeletons, and resilient retry logic for unreliable services.
Micro-frontend Architecture
Module Federation and shell/remote patterns for teams that need independent deployments across large frontend codebases.
// Technical standards
What makes a React codebase maintainable at scale
React's flexibility is both its strength and its pitfall. Without architectural decisions made early, large React codebases become spaghetti: deeply nested prop chains, uncontrolled re-renders, unmaintainable folder structures, and inconsistent data-fetching patterns.
We define architecture before writing features: folder structure, state ownership, API layer design, component composition patterns, and testing strategy. These decisions are documented so the team can maintain them independently.
// Standards
- TypeScript — strict mode on all projects
- Feature-based folder structure with clear boundaries
- TanStack Query or SWR for all server state
- Zustand for local UI state where needed
- React Testing Library — test behaviour, not implementation
- Storybook for shared component documentation
- ESLint + Prettier enforced in CI
- Bundle analysis on every release with size regression checks
// FAQ
React.js development questions
When should we choose React over a meta-framework like Next.js?+
Pure React SPAs make sense for authenticated dashboards, internal tools, and applications where SEO is not required and the full page is behind login. When you need server-side rendering, SEO, static generation, or edge performance, Next.js is the better choice. We recommend per project.
How do you structure large React applications?+
We use feature-based folder structure, barrel exports, domain separation, typed API layers, shared UI component libraries, and strict linting rules. Architecture decisions are documented so the codebase scales with your team rather than accumulating debt.
How do you handle React performance at scale?+
We profile before optimising — using React DevTools Profiler, Lighthouse, and production RUM. Common fixes we apply: memoisation of expensive computations, virtualisation for long lists, code splitting by route and feature, server state deduplication, and eliminating render cascades from poor context design.
Do you write tests for React applications?+
Yes. We write unit tests with Vitest or Jest, integration tests with React Testing Library, and end-to-end tests with Playwright for critical journeys. Test strategy is defined in the architecture phase based on risk and velocity requirements.
