Why experienced React developers matter
A well-structured React app reduces bugs and speeds up iterations.
React is a library, not a framework. Without senior engineers who understand component architecture, state management, and SSR, you end up with tangled code that breaks on every update. IRPR's team has shipped 200+ React projects across 50+ countries.
We use Next.js for server-side rendering, TypeScript for type safety, and React Query for data fetching. This stack cuts page load times by up to 40% compared to client-only apps. We also set up testing with Jest and Cypress from week one.
The difference between generic dev shops and IRPR
Our process removes the guesswork from React app development.
Most agencies talk about agile but hand over a mess of untyped components and no CI/CD. IRPR writes code the way your internal team would: clean, documented, and shippable.
From the Roadmap phase (week 2) you get a fixed price and a detailed backlog. No scope creep. No surprises. Every project includes a handover document and a 30-day maintenance window.
- No type safety – prop errors in production
- No unit tests – every deploy is risky
- No SSR – slow initial load, bad SEO
- No design system – inconsistent UI
- No handover docs – you're stuck
- Hourly billing – budget blows up
- TypeScript by default – zero runtime type errors
- Jest + Cypress – 90%+ test coverage
- Next.js SSR – first paint under 2 seconds
- Storybook component library – reusable UI
- Full documentation and deployment guide
- Fixed price – you know the cost upfront
How we build your React app in 12 weeks
Our process turns your idea into a shipped product, on time and on budget.
We use a four-phase approach that de-risks every step. By the end of week 2 you have a detailed roadmap with wireframes, tech stack decisions, and a fixed price.
After roadmap approval, we sprint through development in two-week cycles. You see a working app every Friday. We handle hosting, CI/CD, and domain setup so you can focus on go-to-market.
What ships with your React app
You get more than code – you get a production-ready system.
Every project includes everything needed to run, maintain, and scale your app. No hidden fees, no missing pieces.
We deliver on your infrastructure so you own the entire stack from day one. Our team stays on chat for 30 days post-launch to handle any questions.
- Source code in your GitHub repository
- CI/CD pipeline with GitHub Actions or Vercel
- Deployed staging and production environments
- Sentry error tracking configured
- Google Analytics or Plausible integration
- TypeScript with strict mode enabled
- Jest + React Testing Library test suite
- Storybook components with visual regression tests
- Lighthouse score report (target 90+)
- Admin user guide and deployment runbook

Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write a line of code.
Senior engineers only
IRPR hires engineers with 6+ years of React experience. Every team member has shipped at least 5 production apps with TypeScript and Next.js. No junior developers.
Full code ownership
You get every file we write. No black boxes, no proprietary frameworks. Your code lives in your GitHub repo from day one. You can take it to any other team.
12-week timeline guarantee
We ship in 8 to 12 weeks for most React apps. Our process is tuned for speed without cutting corners. 98% of our projects deliver on or ahead of schedule.
Production-grade infrastructure
We set up CI/CD, Sentry error tracking, and Cloudflare CDN. Your app runs on AWS or Vercel with auto-scaling. We handle deployment so you don't need a DevOps hire.
Post-launch support included
Every project includes 30 days of post-launch support. Our team monitors Sentry, fixes critical bugs within 4 hours, and stays on Slack for questions. No extra cost.
