This website runs on Next.js 15 App Router with React 19 Server Components. We did not hire another agency to build it. UltimaBot and UltimaWriter, React SaaS platforms for Steven, have been maintained by our team since 2019. That is what production React looks like.

React That Runs in Production

A React Company Whose Own Site Is Built in Next.js 15

The most credible claim a React development company can make is that their own products run on the stack they sell. www.cvinfotech.com is built in Next.js 15 with App Router, React 19 Server Components, TypeScript strict mode, and Tailwind CSS. Every performance decision, every schema implementation, every accessibility choice on this site is the result of the same thinking we apply to client projects. UltimaBot and UltimaWriter, AI SaaS platforms maintained for Steven since 2019, are React and Next.js applications that have evolved significantly over seven years on the same technical foundation.

React is a JavaScript library, not a full framework. Building a production web application in plain React requires assembling your own stack: a router, a state manager, an HTTP client, a build tool, and a server strategy. For most production applications in 2026, the right answer is Next.js, React's full-stack framework. Next.js 15 adds App Router (file-based routing), React Server Components (server rendering without client JavaScript), Server Actions (form mutations without API routes), static and dynamic rendering, and image optimisation built in. We recommend Next.js for new projects. We also build plain React where the application architecture genuinely does not need server-side rendering.

We build React web applications, Next.js full-stack applications, React Native mobile apps, and MERN stack (MongoDB, Express, React, Node.js) systems. For mobile: React Native. For full-stack: MERN stack. For framework comparison: React vs Angular vs Vue.

Production Proof

UltimaBot and UltimaWriter have run in production since 2019. www.cvinfotech.com runs on Next.js 15 today. We do not demo React, we maintain React applications.

React 19 and Next.js 15

New projects are built on the latest stable versions: React 19 Server Components, Next.js 15 App Router, TypeScript strict mode. No legacy patterns carried over from 2018.

$30/Hour vs $100-200 US Rate

The same React expertise at a fraction of the cost. Published rate. No negotiation. The same rate our 512 Freelancer reviews were earned at.

100% In-House

Every React developer, TypeScript engineer, and QA tester is a direct CV Infotech employee. Your codebase never leaves our team.

What We Build

React and Next.js Development Services

Next.js Web Applications

Full-stack Next.js 15 development: App Router, React Server Components, Server Actions, image optimisation, and TypeScript. For SaaS products, marketing sites, and content platforms requiring server-side rendering and strong SEO.

React SaaS Platforms

Complex SaaS products with multi-tenancy, subscription billing (Stripe), authentication (Clerk/Auth0), role-based access control, and real-time data. UltimaBot and UltimaWriter are examples of the complexity we handle over long timelines.

React Dashboards and Admin Panels

Data visualisation, sortable data tables, complex form systems, real-time updates, and role-controlled interfaces. Built with Recharts, TanStack Table, React Hook Form, and shadcn/ui components.

AI-Integrated React Applications

GPT-powered chat interfaces with streaming responses, embedding-based search, document analysis UIs, and recommendation system frontends. React's ecosystem for AI UIs (Vercel AI SDK, custom streaming) is the strongest in the market.

React Code Audits and Migrations

Architecture review, bundle size analysis, Server/Client Component boundary assessment (Next.js App Router), TypeScript coverage audit, and migration from legacy React patterns (Class components, Create React App) to modern hooks and App Router.

React Component Libraries

Design system implementation in React: accessible components built on Radix UI or shadcn/ui, Storybook documentation, TypeScript-typed props, and Figma-to-React handoff. For product teams that need a consistent component layer across multiple applications.

Why CV Infotech

The React Company Whose Own Site Is the Proof

The standard pitch for a React development company is a portfolio of client screenshots and a tech stack list. Our pitch is different: type www.cvinfotech.com/sitemap.xml into a browser and see a Next.js 15 App Router sitemap. View the source of any page and see React Server Component markup. Steven's AI platforms have run on React since 2019. The proof is live.

This is not the right engagement if you:

  • Need React prototyping without a technical scope and architecture review
  • Want to use React on a project that would be faster and cheaper in a simpler stack
  • Expect delivery without a discovery call and written scope
  • Are looking for the cheapest quote, not the most considered one

For simple landing pages and brochure sites, Next.js is overkill. We will tell you that in the call.

7 Years of React Production

UltimaBot: 2019. Still active. Same team. The React codebase has grown and evolved. We did not hand it over and move on.

Next.js 15 on Our Own Site

www.cvinfotech.com is Next.js 15 App Router. React 19 Server Components. TypeScript strict. Not a demo, a live production site with real traffic and real indexing.

React 19 Current

We build on the latest stable React and Next.js releases. React 19 Server Components, Next.js 15 App Router, Turbopack, not patterns from 2020 carried over.

How We Build

From React Brief to Production Deployment

Every React project starts with architecture. The framework choice, the rendering model, and the state management approach are decided before code is written.

01

Framework and Architecture Decision

Day 1

React vs Next.js. App Router vs Pages Router. Server Components vs Client Components. State management selection. Backend architecture. Database schema.

Architecture document before any code is written.
02

Scope and Quote

Days 2-4

Every component, page, API route, and integration mapped to hours. TypeScript interfaces for all data models defined in the scope.

Written scope and fixed-price quote within 48 hours.
03

Design and Component Architecture

Weeks 1-2

Figma designs for all page templates. Component hierarchy mapped. Design system tokens (colours, spacing, typography) defined in Tailwind config.

Approved designs and component architecture document.
04

Development Sprints

Weeks 2-10

Two-week sprints. Deployed to Vercel preview URL at every sprint close, not a local build. TypeScript strict: zero type errors = definition of done per sprint.

Working application on preview URL at every sprint.
05

Performance and Security

Weeks 9-11

Lighthouse/PageSpeed audit, target 90+ on desktop, 80+ on mobile. Core Web Vitals: LCP, CLS, INP measured and optimised. Security review: OWASP Top 10 for the API layer.

Performance report and security checklist.
06

Production Deployment and Handover

Week 11-12

Vercel production deployment (or AWS if specified). Custom domain setup. GA4 and any analytics configured. Full codebase on GitHub repo. Documentation for developer onboarding.

Live application, full handover, 30-day post-launch support.
