What the best React app development partner delivers
IRPR's track record proves results, not promises.
We have shipped over 200 production apps across 50 countries. Our average React project finishes in 12 weeks with 98% on-time delivery.
Every app passes a minimum 99.9% uptime SLA on AWS or Vercel. We use Sentry for error tracking and Lighthouse for performance targets above 90.
Generic dev shops vs the best React partner
Most agencies bill hourly and swap engineers midway. IRPR does the opposite.
When you hire a generic shop, you get estimates that change, code without tests, and a team that disappears after launch.
IRPR assigns senior React engineers who stay until your app is live. We sign a fixed price after the Roadmap phase, and you own every line of code.
- Vague estimates that double mid-project
- Hourly billing with no cap
- Junior developers learning on your project
- No written tests for your components
- Switching engineers every 2 months
- Zero post-launch support
- Fixed price locked in week 2
- No hourly billing, ever
- Senior React engineers with 10+ years each
- Jest, Cypress, and Storybook testing
- Same team from kickoff to release
- 12 weeks of post-launch maintenance
Our React app development process in 4 phases
From idea to release in 12 weeks. Every phase has a clear deliverable.
We start with a 2-day workshop to define your user flows, data model, and core features. By week 2 you have a detailed roadmap with a fixed price.
Sprints run weekly with demos every Friday. You see real code in your staging environment before the final release.
What ships with every React app
No handoff surprises. Every project delivers the full stack below.
We treat code as a product. You get a production-ready app with monitoring, testing, and deployment pipelines from day one.
Everything runs on your own AWS or Vercel account. We never lock you into our infrastructure.
- Full source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions + Vercel
- Automated tests with Jest, Cypress, and React Testing Library
- Sentry error tracking and performance monitoring
- Docker containerization for local development
- Storybook component library with all UI states
- API documentation (OpenAPI or GraphQL schema)
- User analytics setup (PostHog or Mixpanel)
- Responsive design for mobile and tablet
- Accessibility audit and WCAG 2.1 fixes

Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote after the Roadmap phase in week 2. We never bill by the hour. If we discover new work, we quote it as a separate option — no surprise invoices.
Senior engineers only
Every IRPR engineer has at least 8 years of production experience. No juniors, no interns. Our React team averages 12 years of frontend experience.
Weekly demos with your team
We demo working software every Friday. You see real progress in a staging environment, not slides or documents. You can pivot without wasting sprints.
Full code ownership
You own the complete source code, design assets, and infrastructure. No license fees, no platform lock-in. We push everything to your GitHub repository from day one.
Compliance baked in
We add HIPAA, SOC 2, or PCI-DSS controls during development — not as a retrofit. Our engineering playbook includes encryption, audit logs, and role-based access.
Long-term support included
After launch, we provide 12 weeks of free bug fixes and critical updates. You can extend with a monthly retainer for feature work or hosting management.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
