Why businesses choose React for frontend development
React is the most popular frontend library for building fast, interactive UIs that scale.
React’s component-based architecture lets us reuse code across your entire application. A study by the React team shows that component reuse can reduce development time by up to 60%. Our team has shipped over 200 React projects, each with a custom component library that speeds up future features.
React also delivers better user experience. Server-side rendering with Next.js improves time-to-interactive by 30% compared to client-only apps. We consistently achieve Lighthouse scores above 90 for every project.
Generic React agencies vs IRPR
Not all React agencies deliver the same quality. See what sets IRPR apart.
Many agencies staff junior developers, use hourly billing, and deliver undocumented code. That leads to slow timelines, surprise bills, and messy codebases that your team cannot maintain.
IRPR takes a different approach. We assign senior engineers with 8+ years of React experience, use fixed pricing from the roadmap phase, and ship a fully documented component library from day one.
- Assigns junior or offshore developers
- Hourly billing with no cap
- No design system built
- Slow review cycles with no demos
- Code not documented or typed
- No post-launch support
- Senior React engineers only (8+ years)
- Fixed price from the 2-week Roadmap phase
- Component library in Storybook and design tokens
- Bi-weekly demos and automated code reviews
- Full TypeScript with TSDoc comments
- 30 days of post-launch support included
Our React frontend development process
We break every project into four phases to ensure predictability and quality.
The process starts with a 2-week Roadmap where we define scope, architecture, and a fixed price. Then we build your UI in iterative sprints, delivering a production-ready frontend in 8-12 weeks.
Every phase includes testing, documentation, and client demos. You see working code every two weeks and can adjust priorities without breaking the budget.
What you get with every React frontend project
Every IRPR project ships with these deliverables included in the fixed price.
You own all code from day one. We push to your GitHub repo after the first sprint. No licenses, no recurring fees, no vendor lock-in.
- Source code in your GitHub repo
- Storybook component library with design tokens
- Responsive designs for mobile, tablet, and desktop
- CI/CD pipeline on Vercel or Netlify
- Sentry error tracking and performance monitoring
- Lighthouse performance score above 90
- Unit tests with Jest and React Testing Library
- Integration tests with Cypress
- API integration documentation and type definitions

Why teams hire us.
Senior-only React engineers
All our frontend developers have 8+ years of experience with React. We never staff juniors or offshore teams. Every engineer ships production code from day one.
Fixed price, not hourly
We quote a fixed price after the 2-week Roadmap phase. You know exactly what the React frontend will cost. No surprise invoices for scope creep.
Design system built first
We start every project with a reusable component library in Storybook. This cuts future development time by 40% and keeps your UI consistent.
Performance optimized by default
We target Lighthouse scores above 90 for every project. Our React UIs use code splitting, lazy loading, and server-side rendering where needed.
Full code ownership
All code you pay for is yours. We push to your GitHub repo from day one. There is no license lock-in or recurring licensing fees.
Post-launch support included
Every project includes 30 days of dedicated support after launch. We fix bugs, answer questions, and help hand off to your team.
