React Built to
Last in Production
Not Just to Demo
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.
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.

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.
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.

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.
Framework and Architecture Decision
Day 1React vs Next.js. App Router vs Pages Router. Server Components vs Client Components. State management selection. Backend architecture. Database schema.
Scope and Quote
Days 2-4Every component, page, API route, and integration mapped to hours. TypeScript interfaces for all data models defined in the scope.
Design and Component Architecture
Weeks 1-2Figma designs for all page templates. Component hierarchy mapped. Design system tokens (colours, spacing, typography) defined in Tailwind config.
Development Sprints
Weeks 2-10Two-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.
Performance and Security
Weeks 9-11Lighthouse/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.
Production Deployment and Handover
Week 11-12Vercel production deployment (or AWS if specified). Custom domain setup. GA4 and any analytics configured. Full codebase on GitHub repo. Documentation for developer onboarding.
