React Development
Company
India
We build React applications that perform under real production conditions. Single-page applications, SaaS dashboards, real-time interfaces, and AI-powered frontends — delivered by a senior team at $30/hour from Gurugram, India, for clients across the USA, UK, and Australia.
React development that ships, scales, and stays maintainable
React is the most widely deployed JavaScript UI library in production. Over 12 million websites and applications use it. The reason is not hype — it is the component model, the ecosystem, and the predictability of how React applications behave at scale. CV Infotech has been building React applications since 2013. We have shipped React codebases that are still in active production 8 years later, including UltimaWriter and UltimaBot — AI-powered platforms used daily by thousands of users. That continuity happens because of the decisions made at the start: TypeScript strict mode, a predictable state management pattern, co-located tests, and a component architecture that lets a new developer understand the codebase within a day.
Most React projects fail not because React is the wrong tool but because the codebase was never structured for a team. A solo developer building fast can make state management decisions that are invisible until you add a second developer — and then you are refactoring instead of shipping. We apply the same discipline to a 6-week MVP that we would apply to a 12-month product: every component has a clear responsibility, every piece of shared state has an explicit owner, and every API call goes through a typed abstraction layer. That discipline is what our clients — including John Gowland's real estate platform and Steven's UltimaBot AI platform — describe when they say the code was easy to hand off and maintain.
One honest point about when you do not need us: if your project is a marketing landing page or a simple informational site with minimal interactivity, React is likely the wrong tool and CV Infotech is the wrong partner. A well-built WordPress or static HTML site will load faster, cost less, and require less maintenance for that use case. We say this because we would rather send you to the right solution than take a project that does not suit our strengths. If your project involves real application logic — user authentication, complex state, real-time updates, data-heavy dashboards, or API-driven content — React and our team are the right fit. Explore our React.js development service and our broader web development capability for more context.
TypeScript strict mode — always
Every CV Infotech React project uses TypeScript in strict mode. No any, no implicit casts, no type assertions without explicit justification. This adds hours at the start and saves days of debugging in production.
State management that makes sense
We choose state management based on what your application actually needs — not what is currently popular. Simple applications get Context. Complex ones get Zustand or Redux Toolkit with typed slices. We document the decision so the next developer understands it.
Performance from day one
Code splitting, lazy loading, memoisation, and bundle analysis are built into our build pipeline, not added as an afterthought. Our React applications consistently score 95+ on Lighthouse.
You own the code completely
Full source code transferred on final delivery. No vendor lock-in. We use no proprietary frameworks or tools that require our ongoing involvement. Any competent React developer can pick up the codebase.
What we build with React
From single-page applications to AI-powered interfaces and React Native mobile apps — senior React engineering for USA, UK, and Australian businesses.
Single-Page Applications (SPAs)
React SPAs for SaaS products, internal tools, and customer-facing portals. Optimised routing with React Router or Next.js App Router. Code-split by route so initial load stays fast regardless of application size.
Learn moreAI-Powered React Interfaces
Streaming AI responses, real-time token rendering, prompt management UIs, and LLM integration layers. We have built production AI interfaces for clients using OpenAI, Anthropic, and custom model endpoints.
Learn moreSaaS Dashboards and Admin Panels
Complex data tables, filterable reports, multi-step workflows, and permission-based UI — built with React, TypeScript, and a design system that scales as you add features. Recharts, Tanstack Table, and custom chart components.
Learn moreReact + Next.js Full-Stack Applications
Server-side rendering, static generation, API routes, and middleware — all within a single Next.js 15 App Router codebase. We handle deployment to Vercel, AWS, or your own infrastructure.
Learn moreReact Native Mobile Apps
iOS and Android apps that share a business logic layer with your React web application. Consistent data handling, shared type definitions, and a single team who understands both sides of the stack.
Learn moreLegacy React Codebase Rescue
React 16 or 17 codebases with class components, tangled state, and no TypeScript. We audit the codebase, present a phased migration plan, and execute it without stopping your product roadmap.
Learn moreWhy hire a React development company in India
The engineering quality gap between a senior React developer in Gurugram and one in San Francisco is close to zero. The cost gap is 70 to 85 percent. Here is what that means in practice for businesses in the USA, UK, and Australia.
USA (CCPA, AWS us-east-1, EST)
US companies hiring senior React engineers in-house pay $120,000 to $200,000 per year in base salary alone. US agencies bill $150 to $250 per hour. CV Infotech delivers the same React expertise at $30 per hour — without the overhead of recruitment, onboarding, or benefits. Our team operates on EST overlap hours. CCPA-compliant architecture is part of every US-market project. Infrastructure deployed to AWS us-east-1 by default. US development services.
UK (UK GDPR, AWS eu-west-2 London, GMT)
UK agencies charge £80 to £150 per hour for senior React development. UK GDPR data residency requirements are built into our architecture from day one — not added after an audit finds the problem. We hold GMT-compatible working hours for daily standups and project reviews. AWS eu-west-2 London region used for UK-market applications by default. UK developer hire services.
Australia (Privacy Act 1988, AWS ap-southeast-2 Sydney, AEST)
Australian software development agencies charge AUD $150 to $250 per hour. The time zone difference with India is manageable — AEST morning is IST afternoon, which means Australian businesses get responses and updates during their business hours without our team working overnight. AWS ap-southeast-2 Sydney region. Privacy Act 1988 compliance built into data handling patterns. Australian services.
React since React 0.14
We have been building in React since before hooks existed. We have migrated class components, rebuilt broken codebases, and watched the ecosystem evolve. That history means we know when the current best practice is new enough to be uncertain.
Senior engineers on every project
We do not assign junior developers to handle delivery while seniors do the scoping call. The developer you speak to in the discovery call is the same developer writing the code.
Fixed price before we start
No open-ended hourly billing. We scope the work, agree the price, and do not invoice more than agreed without your explicit approval of a change request.
No minimum contract
Project-based engagement. We do not require retainers or long-term commitments. Clients stay because the work is good, not because a contract requires it.

How we deliver a React project
Discovery first. Fixed price second. Design system third. Then disciplined, milestone-based development with a live preview every sprint.
Technical discovery
2–4 hoursWe read your existing codebase before the discovery call if you have one. If you are starting from scratch, we ask for your Figma designs, API specs, and any technical constraints. We ask specific questions about state management requirements, performance targets, authentication model, and deployment environment. No generic questionnaires.
Fixed-price proposal
24–48 hoursWe send a proposal with a fixed total price, milestone breakdown, payment schedule, and a delivery timeline. The price does not change unless you add scope. If you add scope, we send a change request before starting the new work.
Design system and component library
1–3 weeksBefore writing application logic, we build the design system: colour tokens, typography scale, base components (Button, Input, Modal, Table), and the layout primitives. This is the foundation that makes every subsequent component faster to build and consistent to maintain.
Application development
Milestone-basedDevelopment proceeds in 2-week sprints. At the end of each sprint you receive a deployed preview URL — not a screenshot, not a recorded demo, but a live URL you can click through and test. Every PR goes through a code review before merge. TypeScript errors block deployment.
Performance and security review
3–5 daysBefore final delivery, we run Lighthouse CI across every route, check bundle sizes, run dependency vulnerability scans, and verify that no API keys or sensitive configuration are exposed in the client bundle. Performance issues found here are fixed before handover, not logged as future tickets.
Handover and knowledge transfer
1–3 daysFull source code transferred. README with local setup, environment variables, deployment process, and codebase architecture explanation. A 30-minute walkthrough call for your team. 30 days of post-launch support for bugs — not new features, but genuine defects from the delivered scope.
React Development — Frequently Asked Questions
Ready to build something solid in React?
Send us your brief — a description of what you are building, what you have already, and your timeline. We will review it before the call so the first conversation is about your specific project, not a generic introduction to what we do.
