Why a Senior React.js Development Partner Matters
Building with React is not enough. You need senior engineers who deliver maintainable, scalable code.
Junior React developers produce code that works today but collapses under load. Senior engineers architect for performance, state management, and testing from day one. IRPR assigns only engineers with 8+ years of experience.
Our 200+ shipped products include SaaS, ecommerce, and healthcare apps. Each one uses React with TypeScript, proper component isolation, and a test suite that catches 99% of regressions. This prevents technical debt and keeps your team moving fast.
The IRPR Difference for Senior React.js Development
Most agencies sell you a junior and charge senior rates. IRPR gives you experienced engineers from day one.
We have seen the hidden costs of generic dev shops: scope creep, unreadable code, missed deadlines. Our team built a different model based on transparency and fixed pricing.
Each project starts with a 2-week Roadmap phase that defines scope, tech stack, and a fixed price. You approve the plan before any development begins. No surprises.

- Hourly billing with no cap
- Unclear code ownership
- No testing or CI/CD by default
- Slow communication across time zones
- Blames scope for missed deadlines
- Senior engineers with 8+ years of React experience
- Fixed price locked after 2-week Roadmap
- Full code ownership in your repo
- Jest, Cypress, CI/CD, and Sentry included
- Async-first with daily standups and overlap hours
- On-time delivery for 98% of projects
How We Build Your React.js Application
Our four-phase process turns your idea into a live product with minimal risk.
We use a proven roadmap-to-release method that ensures every project stays on track. Each phase has specific deliverables and a go/no-go decision point.
You are involved throughout: weekly demos, a dedicated Slack channel, and a project manager who reports progress every Monday.
What Ships with Every React.js Project
Every deliverable is production-ready and includes the following by default.
We do not treat testing, deployment, or documentation as optional extras. They are part of every fixed-price engagement.
You get a complete, working application that your internal team can maintain and extend from day one.
- Source code in your private GitHub or GitLab repo
- CI/CD pipeline using GitHub Actions or GitLab CI
- Automated tests with Jest and Cypress (90%+ coverage)
- Deployment to AWS, Vercel, or Netlify
- Error tracking with Sentry
- Performance monitoring with Lighthouse reports
- TypeScript types and documentation in Storybook
- Design system (component library) for future development
- Post-deployment support for 30 days
