React.js Development Developers: What We Build
We build full-stack React applications that ship in 12 weeks.
Our React team has built over 200 products across 50 countries. Each project uses a standardized stack: Next.js, TypeScript, PostgreSQL, and hosted on AWS or Vercel with CI/CD.
We focus on performance and maintainability. Every app includes unit tests with Jest, Sentry error monitoring, and a Storybook component library so your team can iterate after launch.
How IRPR Differs from Generic Dev Shops
We don't build like most agencies. Here's the real difference.
Generic dev shops sell you hours and hope. IRPR sells you a product with a fixed price and a fixed timeline. You know exactly what you get and when.
We use the same senior engineers from kickoff to launch. No handoffs, no junior developers, no surprises.
- Unclear requirements
- Hourly billing
- No code ownership
- Junior developers
- Delays and scope creep
- No CI/CD pipeline
- Fixed price per project
- You own the full code
- Only senior React engineers
- 8-12 week delivery
- CI/CD on GitHub Actions
- Sentry error monitoring
Our React Development Process
We follow a four-phase process that eliminates guesswork.
We start with an Idea phase to define scope and constraints. Then a Roadmap phase produces a fixed quote and timeline. Next comes Product development with 2-week sprints. Finally we Release with full documentation and handoff.
Every phase includes weekly demos so you see the app grow. No black boxes.
What Ships with Every React Project
Every delivery includes production-ready code and DevOps infrastructure.
You don't just get a finished app. You get all the tooling needed to run, maintain, and extend it yourself. No vendor lock-in.
Our standard stack ensures your team can take over immediately after launch.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions
- Sentry error tracking
- Unit tests with Jest
- Storybook component library
- Automated deployment to Vercel
- Admin dashboard with analytics
- API documentation with Swagger
- Responsive design for mobile and tablet
- Performance budget with Lighthouse score >90

Why teams hire us.
Fixed Price, Not Hourly
Every React project gets a fixed quote during the Roadmap phase. No hourly billing means no surprise invoices and no scope creep charges.
Only Senior Engineers
We hire as senior-only engineers with a minimum of 7 years experience. No junior developers. You get an expert who can make architectural decisions from day one.
Full Ownership from Day One
You own all source code, IP, and design assets. We never license or resell your code. Your repo. Your deployment. Your product.
8-12 Week Delivery
Our average project ships in 12 weeks. We use a proven process and a standardized stack to eliminate guesswork and delays.
Modern Stack You Can Maintain
We use Next.js, TypeScript, PostgreSQL, and Tailwind CSS. No obscure frameworks. Your internal team can take over maintenance immediately.
Compliance Ready
We build HIPAA, SOC 2, PCI-DSS, and GDPR compliant apps. We add encryption, audit logs, and role-based access where needed.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
