Senior React.js Development FirmDevelopment Firm
We build production React.js apps with senior engineers only. You get a fixed price, a clear timeline, and code you own from day one.
IRPR is a senior react.js development firm. We use React 18, Next.js 14, TypeScript, and Node.js to build web apps that scale. Every engineer on your project has 7+ years of experience in the React ecosystem.
We ship MVPs in 8-12 weeks for a fixed price between $80K and $250K. Our process covers architecture, component library setup, state management with Redux or Zustand, API integration, and deployment to AWS or Vercel. We also handle compliance like SOC 2, HIPAA, and PCI-DSS.
Founders hire us when they need a production-ready React app fast. CTOs hire us to build internal tools with complex UIs. Product managers hire us when their in-house team is at capacity. We replace the risk of hiring and managing individual contractors.

Why hire a senior react.js development firm
Building with React is fast, but building it right takes experience.
A junior developer can wire up a React component in an hour. But that same component might break under load, fail on accessibility audits, or cause a cascading re-render. IRPR uses senior engineers who write tests with Jest and React Testing Library, enforce TypeScript strict mode, and follow the React 18 concurrent features correctly.
We have shipped 200+ React products. Our engineers have built for startups that scaled to millions of users and for enterprises that require SOC 2 and HIPAA compliance. When you hire IRPR, you get a team that has already solved the hard problems.
Generic dev shop vs IRPR
Not all React shops are equal. Here is what you actually get.
Most agencies assign junior developers to your project to keep costs low. They use boilerplate code, skip testing, and deliver a React app that is slow and hard to maintain. You end up spending more on rewrites than you did on the initial build.
IRPR assigns only senior engineers with 7+ years of experience. We write clean, typed, tested code. We set up CI/CD pipelines, error monitoring with Sentry, and performance profiling with Lighthouse. Your app ships fast and stays fast.
- Junior developers with 1-2 years of React
- No TypeScript or loose types
- No unit tests or integration tests
- Manual deployment to a shared server
- No performance optimization
- Hourly billing with no cap
- Senior engineers with 7+ years of React
- TypeScript strict mode throughout
- Jest + React Testing Library for every component
- Automated CI/CD via GitHub Actions to AWS/Vercel
- Lighthouse scores above 90 on mobile and desktop
- Fixed price from the Roadmap phase
Our process for building your React.js app
We follow a 4-phase framework that removes guesswork.
Every project starts with a 2-week Roadmap phase. We map out the architecture, component tree, data flow, and API contracts. You get a fixed price and a timeline before we write a single line of code.
Then we build in 2-week sprints. You see a working app every sprint. We deploy to a staging environment, run automated tests, and get your feedback. No surprises at the end.
What ships with every React.js project
You get more than a working app. You get a production-ready system.
When IRPR delivers your React.js app, you own everything. The code, the infrastructure, the pipeline. We do not use proprietary templates or lock you into a platform.
Every project includes a full CI/CD pipeline, error tracking, and performance monitoring. Your team can take over immediately.
- Full source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions + Vercel or AWS
- TypeScript strict mode configuration
- Unit tests with Jest and React Testing Library
- Sentry error tracking and performance monitoring
- Lighthouse performance report (target 90+)
- Component library documentation with Storybook
- Deployment guide and runbook
- 30 days of post-launch support
