IRPR is a React.js development agency that ships production-grade web apps using Next.js, TypeScript, and Node.js. Our senior engineers build single-page applications, dashboards, and full-stack platforms.
We deliver in 8-12 weeks with fixed pricing from $80K to $250K. Every project follows our Idea-Roadmap-Product-Release framework. We handle compliance like SOC 2, HIPAA, and GDPR where needed.
Our clients are SaaS founders who need a fast MVP, enterprise teams modernizing legacy frontends, and startups building customer-facing apps. We also work with agencies needing white-label React development.
Types of software we ship.
Single-page application (SPA)
Build a fast client-side app using React Router and Redux Toolkit. Perfect for tools where page reloads break the flow.
Progressive web app (PWA)

Why React.js for your next project
React.js powers hundreds of millions of user interfaces every day.
React.js is maintained by Meta and used by companies like Netflix, Airbnb, and Uber. Its component model makes code reusable and easier to test. We have shipped over 200 React projects for clients in 50+ countries.
With React.js, you get a huge ecosystem of libraries and tools. State management with Zustand or Redux, SSR with Next.js, and styling with Tailwind or styled-components. We help you choose the right stack for your product.
Fixed price vs hourly billing
Most agencies bill hourly and change requirements. We don't.
Hourly billing incentives are wrong. The longer a project takes, the more the agency earns. That leads to slow timelines, scope creep, and surprise invoices. IRPR charges a fixed price after the Roadmap phase.
We define the full scope in week 2 during Roadmap. You get a fixed quote with no hidden fees. If requirements change, we adjust the quote before building. No surprises.
- Hourly billing with unknown total cost
- Slow to start - weeks for a proposal
- Junior or offshore developers
- No dedicated QA - bugs slip through
- You own no code until paid in full
- Communication via email - slow response
- Fixed price locked in week 2
- Kickoff in 5 business days
- Senior React engineers only - 7+ years experience
- Automated testing and code review every sprint
- Full code ownership from day one
- Daily Slack updates - respond in minutes
How we build your React.js app
Our process is designed for speed and clarity.
We start with a 2-day discovery sprint to understand your goals, users, and constraints. Then we produce a Roadmap document with wireframes, user stories, and a fixed price.
After you approve the Roadmap, we build in 2-week sprints. You see working software every 14 days. We deploy to staging so you can test on real devices. Finally we ship to production with CI/CD and monitoring.
What ships with every React.js project
You get more than code. You get a production-ready system.
Every project includes a complete CI/CD pipeline, automated testing, and documentation. We set up monitoring with Sentry and Datadog so you catch errors before users do.
Source code lives in your GitHub repository from day one. You own everything. We provide a handover guide and post-launch support for 30 days.
- Full source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions and Vercel
- Unit tests with Jest and React Testing Library
- End-to-end tests with Cypress or Playwright
- Sentry error tracking with alerts
- Datadog or New Relic performance monitoring
- Responsive design for mobile and tablet
- SEO metadata for every page (Next.js)
- Accessibility audit (WCAG 2.1 AA)
- 30-day post-launch support

8-12 week MVP guarantee
We ship a production-ready MVP in 8 to 12 weeks. Our framework (Idea-Roadmap-Product-Release) eliminates delays. 98% of projects finish on time.
Full code ownership
You get all source code in your GitHub repo from day one. There are no licenses or royalties. You can take the code anywhere after launch.
