Why IRPR is Your Professional React.js Development Agency
We have delivered 200+ React products across 50 countries with a 98% on-time track record.
Every React project starts with a two-week Roadmap phase where we audit your requirements, design the component tree, and define the data flow. We use Next.js for server-side rendering when SEO matters, or Create React App for lightweight SPAs. Our default stack includes React Query for API caching, Zustand for client state, and Tailwind CSS for styling.
We also enforce strict testing standards: every component gets unit tests with Jest and React Testing Library, integration tests with Cypress, and visual regression tests with Chromatic. This keeps bug rates below 2% post-launch.
Generic Dev Shop vs Professional React.js Agency
Most agencies build React apps that break after six months. IRPR builds apps you can extend for years.
Generic shops often use boilerplate code, skip automated testing, and deliver without documentation. That leads to slow bug fixes, high technical debt, and painful onboarding for new developers.
IRPR delivers clean, typed, and documented React applications. We create a Git-based development workflow, provide a Storybook for every component, and include CI/CD pipelines so your team can deploy on day one.
- Unclear delivery timelines
- Hourly billing with surprise overruns
- No compliance certifications
- Minimal automated testing
- You do not own the code until final payment
- Slow email-only communication
- Fixed price locked in week 2 of Roadmap
- 8-12 week delivery with weekly demos
- SOC 2 / HIPAA / PCI-DSS compliance built in
- 80%+ test coverage, CI/CD with GitHub Actions
- Full source code ownership from day one
- Daily standups and Slack-based communication
Our React.js Development Process
We use a four-phase process that eliminates guesswork. You know exactly what you get and when.
Every engagement begins with a two-day kickoff where we pair you with a senior React engineer and a project manager. We audit your existing tech stack, define user stories, and set up a shared task board in Linear.
By week 2 you have a detailed Roadmap document with a fixed price and a delivery calendar. No scope creep, no hidden fees.
What Ships with Every React.js Project
You are not just getting code. You get a production-ready system with everything your team needs to operate.
Our deliveries go beyond the application itself. We include all infrastructure as code, monitoring setup, and documentation that your team can read and update. Every project ends with a handoff session where we walk through the architecture and deployment process.
If you need ongoing support, we offer monthly retainers starting at $8,000. Typical retainer includes bug fixes, minor feature additions, and dependency upgrades.
- Source code in your private GitHub repository
