Why IRPR is the Best React.js Development Company
We are a team of senior React.js engineers who have shipped 200+ products for clients in 50+ countries.
Every project is led by a developer with 8+ years of experience in React and related ecosystems. We use Next.js for server-side rendering, Redux for state management, and TypeScript for type safety.
Our fixed price model means you know the exact cost after the 2-week Roadmap phase. No hourly billing, no scope creep. Average delivery is 12 weeks, and 98% of our projects launch on time.
The Difference Between IRPR and Generic Dev Shops
Most agencies charge by the hour and deliver late. IRPR delivers on time, on budget, with senior engineers only.
Generic dev shops often assign junior developers, change scope mid-project, and leave you with unmaintainable code. They rarely give you full ownership or transparent reporting.
IRPR treats your project like our own. You get a fixed price, weekly demos, full code ownership, and a 30-day post-launch support period. We use automated testing and CI/CD from day one.
- Unclear scope and change orders
- Hourly billing with surprises
- Junior developers on your project
- Code stays with the agency
- No CI/CD setup
- Slow email-only communication
- Fixed price after 2-week Roadmap
- Weekly demos with your team
- Senior engineers with 8+ years
- Full code ownership transferred
- CI/CD with GitHub Actions included
- Slack-based daily updates
Our React.js Development Process
From idea to production in 12 weeks, with a clear roadmap and transparent milestones.
We start with a 2-week Roadmap phase where we define the tech stack, architecture, and exact scope. You get a fixed price and timeline before any development begins.
Then we run 10 weeks of development sprints with bi-weekly demo days. After launch, you get 30 days of free support and a handover package including source code, CI/CD, and documentation.
What Ships with Every React.js Project
Every project includes a complete production-ready codebase with CI/CD, monitoring, and documentation.
You get more than just code. We deliver a full ecosystem that your team can maintain and extend from day one.
- Source code in your private GitHub repository
- CI/CD pipeline using GitHub Actions or GitLab CI
- Sentry error monitoring and performance tracking
- Docker containers for local and production environment
- Automated unit and integration tests (Jest + Cypress)
- API documentation with Swagger or GraphQL schema
- Lighthouse performance report (target score 90+)
- SEO metadata and sitemap for Next.js apps
- Responsive design tested on 10+ device sizes
