Our clients save an average of 6 months of hiring time by using our team. We handle architecture, development, testing, and deployment so you can focus on business logic and growth.
Generic dev shop vs IRPR
The difference in how we build React.js applications.
Most development agencies staff projects with junior developers and charge by the hour. They skip security audits, deliver undocumented code, and change pricing mid-project. This leads to budget overruns and technical debt.
IRPR assigns senior React engineers with 8+ years of experience. We provide a fixed price after a 2-week Roadmap phase. Every project ships with CI/CD, security compliance (SOC 2, HIPAA), and full code ownership.
- Hires junior developers with less than 3 years experience
- Charges by the hour with no cap
- No fixed pricing or scope protection
- No security audits or compliance support
- No automated CI/CD or error tracking
- Code ownership is unclear or shared
- Senior React engineers (8+ years experience)
- Fixed price from Roadmap phase (week 2)
- Weekly demos and transparent progress
- SOC 2, HIPAA, PCI-DSS compliance built in
- Automated CI/CD with GitHub Actions and Sentry
- Full code ownership from the first commit
Our React.js development process
From idea to production in 8-12 weeks.
We use a structured 4-phase process that ensures your project starts right and ships on time. Every phase includes client reviews and automated testing so there are no surprises at launch.
The Roadmap phase in week 2 defines the full scope and fixed price. We then move to weekly sprints with production-ready code deployed to a staging environment. Final deployment includes a runbook and 30-day support.
What ships with every React.js project
Production-ready deliverables you get from day one.
Every project we deliver includes a complete production environment, not just code. You can deploy immediately and scale without rewriting anything.
- Complete source code in your GitHub repository
- CI/CD pipeline with GitHub Actions
- Sentry error tracking and performance monitoring
- Unit tests with Jest and React Testing Library
- Storybook for component documentation
- Performance report (Lighthouse score >90)
- Deployment guide and runbook
- Admin dashboard with user and role management
- API integration with Stripe, Auth0, or custom backend
- 30 days of post-launch support and bug fixes
