Why choose the best React.js development firm?
IRPR delivers production React apps on time and on budget.
Every project starts with a two-week roadmapping phase where we define scope, tech stack, and timeline. You get a fixed price quote before any code is written.
Our senior engineers average 10+ years of experience. We use TypeScript by default, write unit and integration tests, and deploy with CI/CD pipelines from day one.
The difference between a generic dev shop and the best React.js development firm
Not all React agencies are built the same. Here is how IRPR stands apart.
Generic shops often give vague estimates, staff junior developers, and rarely audit for performance or accessibility. They may not write tests or set up monitoring.
IRPR assigns senior engineers only, provides a fixed price after the roadmapping phase, and ships with full test coverage and Sentry error tracking. Your code is always in your own repository.
- Vague ballpark estimates
- Junior or mixed-skill teams
- No upfront scope clarity
- No QA process defined
- Code may be owned by agency
- Slow to start, no fixed timeline
- Fixed price after 2-week roadmap
- Senior engineers only (10+ years)
- Scope lock in roadmapping phase
- Automated testing + CI/CD
- Full code ownership from day one
- 2-week kickoff, 8-12 week delivery
How we build your React.js application
Our process is transparent and predictable.
We start with a two-week Discovery Sprint to understand your users, business goals, and technical constraints. This produces a detailed product roadmap and a fixed-price contract.
Development runs in two-week sprints with daily standups and end-of-sprint demos. You see working software every 14 days and can adjust priorities as needed.
What ships with every React project
Every build includes production-ready deliverables out of the box.
We don't just hand over code. Every project ships with a complete foundation for long-term success: testing, monitoring, deployment automation, and documentation.
This means you can take over the codebase or hand it to your internal team without friction. No missing pieces.
- Source code in your private GitHub repository
- CI/CD pipeline on GitHub Actions
- Unit tests with Jest, integration tests with Cypress
- Sentry error tracking and performance monitoring
- Storybook component library with visual regression tests
- Deployment scripts for AWS, Vercel, or your own server
- API integration examples (Stripe, Auth0, Postgres)
- Mobile responsive design and accessibility audit (WCAG 2.1 AA)
- Technical documentation including architecture decisions
