Senior React.js Development Studio with a Proven Track Record
Our stats speak louder than buzzwords. Every number comes from real projects with real clients.
IRPR has shipped over 200 React.js applications across 50+ countries. Our team consists of senior engineers who have worked at companies like Google, Microsoft, and Stripe. We focus on clean code, performance, and maintainability.
We deliver 98% of projects on time and on budget. Our average project runs 8-12 weeks from kickoff to production. Clients report a 40% reduction in time-to-market compared to previous agency engagements.
What Sets a Senior React.js Development Studio Apart
Not every agency can deliver senior-level work. Here is how IRPR differs from the rest.
Most development shops staff junior or mid-level engineers. They bill hourly and change scope without notice. Their code often requires heavy refactoring within a year.
IRPR assigns only senior engineers with 10+ years of experience. We give a fixed price after a 2-week Roadmap phase. Every project is delivered with a full test suite, CI/CD pipeline, and documentation.
- Junior/mid-level developers
- Hourly billing with no cap
- Unclear scope changes mid-project
- No automated testing
- No security compliance (HIPAA, SOC 2)
- No post-launch support
- Senior engineers only (10+ years)
- Fixed price after Roadmap phase
- Clear scope with change control
- Full test suite (Jest, Cypress, Playwright)
- Built to HIPAA, SOC 2, PCI-DSS standards
- Sentry error tracking and uptime monitoring
Our Process: From Idea to Production React.js App
We follow a structured 4-phase process that de-risks your investment and delivers a working product fast.
Every engagement starts with a 2-week Roadmap phase where we define requirements, create a prototype, and set a fixed price. This phase costs $5,000 but is credited toward the build.
After approval, our team architects and builds the app in 8-10 weeks. You get a deployment-ready application with all source code, documentation, and a CI/CD pipeline in your repository.
What Ships with Every Senior React.js Project
When you work with IRPR, you get more than just code. Every deliverable is designed to make your team productive from day one.
We believe in full transparency and no lock-in. You own everything we build, and we provide all the tools needed to maintain and scale the app yourself.
- Source code in your private GitHub repository
- CI/CD pipeline with GitHub Actions and Vercel/AWS
- Automated unit tests (Jest), integration tests (Cypress), and accessibility audits (axe)
- React component library built with Storybook and TypeScript
- Sentry error tracking and Datadog performance monitoring
- Documentation: architecture overview, API endpoints, deployment guide
- One-click deployment script for staging and production
- 30-day post-launch warranty with bug fixes
- Sprint demo recordings and all meeting notes
- Admin dashboard for non-technical users to manage content
