React JS
Development
Company India
Custom React and Next.js web applications for businesses in the USA, UK and Australia. TypeScript-first. Component-driven. Production-ready. Fixed-price.
The React JS Development Company USA & UK Businesses Trust
React development in the US and UK market is expensive. Senior React engineers in San Francisco or London command $120–$200 per hour. A mid-complexity React web application built by a US agency costs $30,000–$100,000. For enterprise dashboards, SaaS platforms and headless frontends, budgets routinely exceed $150,000. Most of that price covers talent market overhead, not engineering quality.
CV Infotech has been building React applications since React 0.14. Our frontend engineers in Gurugram, India have delivered over 300 React and Next.js applications for startups, scale-ups and enterprises across the USA, UK and Australia — from single-page marketing sites to complex SaaS dashboards with real-time data, multi-tenant architecture and custom component libraries used across product suites.
Whether you need a custom React web app, a Node.js backend to power it, a full MERN stack team or a React Native mobile app alongside your web product, our team delivers production-ready React applications on time, within budget and fully documented.
TypeScript on Every Project
We write TypeScript by default — not JavaScript. Full type coverage across components, hooks, API responses and utilities. Codebases that are readable, maintainable and safe to refactor.
Next.js for SEO-Critical Projects
Any React project that needs to rank on Google uses Next.js with SSR, SSG or ISR. Pure SPAs (dashboards, internal tools) use Vite. We always recommend the right architecture for your specific requirements.
Component-First Development
We build components in Storybook before assembling pages. You get a living component library as a by-product of your application — reusable, documented and testable in isolation.
Fixed Price — No Hourly Rate
Every React project starts with a detailed fixed-price proposal. We have never sent a surprise invoice in 12 years. The price we quote is the price you pay — guaranteed before work begins.

Learn moreWhy Engineering Teams Choose CV Infotech for React
Not junior developers following tutorials — experienced React engineers who have shipped production applications. Here is what separates us from most offshore React teams.
For US Product Teams
We work as an extension of US product and engineering teams — daily standups, GitHub pull requests, code reviews in your codebase, Jira/Linear sprint ceremonies. We match your engineering culture, not impose ours. See our US development services.
For UK Agencies & Startups
White-label React development for UK digital agencies. Full-stack React builds for UK startups raising pre-seed through Series A. Explore our UK developer hire services.
For Australian Scale-Ups
React development for Australian SaaS companies and scale-ups. IST overlaps AEST mornings for daily syncs. We have supported Australian product teams for over a decade. See our Australian services.
TypeScript-First Engineers
Every developer writes strict TypeScript. No any types. Full coverage on components, hooks, API clients and utility functions.
Architecture Before Code
We document the component hierarchy, data flow and state strategy before the first PR. No architectural surprises midway through a build.
Component-Driven with Storybook
Components built and reviewed in isolation before page assembly. You get a living component library as a deliverable.
Testing Is Not Optional
Jest unit tests, React Testing Library integration tests and Playwright E2E. We do not hand over untested React code.
Technologies We Use to Build Your React Application
React 18, Next.js 14 and TypeScript form the core. Everything else is chosen based on your specific project requirements — not trend.
React 18
FrameworkConcurrent rendering, Suspense, automatic batching, useTransition and the latest React hooks. We use React 18 on every new project.
Next.js 14+
Full-StackApp Router, Server Components, Server Actions, ISR, edge functions and Vercel deployment. Our default for all commercial React projects.
TypeScript
LanguageStrict TypeScript on all projects. Full type coverage across components, hooks, API responses and utility functions. Zero any types.
React Query
DataTanStack Query for server state, caching, background refetching, optimistic updates and synchronisation across components.
Tailwind CSS
StylingUtility-first CSS for rapid, consistent UI development. Custom design tokens, dark mode and fully responsive layouts without CSS bloat.
Zustand
StateLightweight client state management. Used when React Query does not cover the client state requirement and Redux is overkill.
Storybook
ComponentsComponent development and documentation in isolation. Used for all component library projects and design system builds.
Vite
Build ToolLightning-fast HMR and build tool for React SPAs and internal tools. Used instead of Create React App for all non-Next.js projects.
Why We Default to Next.js for React
Most React tutorials start with Create React App or a plain Vite setup — which produces a client-side SPA. SPAs are excellent for dashboards, internal tools and authenticated applications where SEO does not matter. For any commercial React project that needs to rank on Google, SPAs are the wrong choice. Search engine crawlers still struggle with client-rendered JavaScript content.
Next.js gives you React with server-side rendering, static generation, incremental static regeneration and the App Router — all of which produce pre-rendered HTML that search engines can index correctly. Combined with our Node.js backend and MERN stack capabilities, we can build the complete full-stack application — not just the frontend.
For React Native mobile applications, our React Native team can build iOS and Android apps that share business logic with your React web application — reducing the total cost of maintaining two separate frontends.

How We Build Your React Application
Architecture first. Components second. Integration third. Testing always. A disciplined process that produces React applications you can actually maintain.
Architecture & Technical Discovery
Week 1We design the React application architecture before writing a line of code — component hierarchy, data flow, state management strategy, routing, API layer design and deployment environment. For Next.js projects, we define which pages use SSR, SSG or ISR based on SEO and performance requirements.
UI Design & Component Specification
Weeks 2–3Figma designs with a defined component library — every UI element specified before development starts. Design tokens, spacing scale, typography and colour system defined and shared with your team. Mobile-first responsive layouts across all breakpoints.
React Development — Component-First
Weeks 4–14+ (scope-dependent)We build components in isolation using Storybook, then assemble them into pages and features. Weekly staging deployments on Vercel with shareable preview URLs. You review real working code each sprint — not mockups or screenshots.
Testing, QA & Performance
Final 2 WeeksJest and React Testing Library unit tests, Playwright end-to-end tests, Lighthouse performance audit, WCAG 2.1 accessibility audit, cross-browser testing (Chrome, Safari, Firefox, Edge) and Core Web Vitals compliance on production build.
Deployment & Handover
30 days post-launch freeProduction deployment to Vercel, AWS or your preferred hosting. CI/CD pipeline setup with GitHub Actions. Full codebase handover with documentation, component Storybook, architecture notes and 30-day post-launch support for bugs and questions.
