React.js Development Consultants Deliver Results
Our React.js consultants have shipped over 200 products across 50 countries with a 98% on-time rate.
Each project starts with a 2-week Roadmap phase to lock scope, architecture, and a fixed price. After approval, we deliver a production-ready MVP in 8-12 weeks.
We use Next.js for server-side rendering, React Query for data fetching, and Playwright for end-to-end testing. Every ship includes CI/CD, automated tests, and performance monitoring.
The Difference Between IRPR and Generic Dev Shops
Most agencies promise cheap hourly rates and deliver overblown timelines. IRPR works differently.
Our React.js development consultants are all senior-level engineers with an average of 10+ years of experience. We do not hire juniors or offshore teams.
Every project has a dedicated project manager, daily standups, and a clear Roadmap. We ship working software every sprint, not every quarter.
- vague estimates that balloon 2x
- junior or mid-level engineers
- no dedicated project manager
- code with minimal tests
- no CI/CD setup
- vanishes after launch
- fixed price locked in Roadmap
- senior-only engineers (10+ yr avg)
- dedicated PM with daily standups
- unit + E2E tests in every sprint
- CI/CD from day one
- 30-day warranty and optional retainer
How Our React.js Development Consultants Build
We follow a four-phase process designed for speed and quality.
Phase 1 is Discovery & Architecture, where we define user stories, data models, and the tech stack. Phase 2 is Sprint Planning, where we break work into 1-week sprints with clear acceptance criteria.
Phase 3 is Build & Test: we develop features, write automated tests, and deploy to staging every week. Phase 4 is Deploy & Iterate, where we push to production, monitor with Sentry, and hand over ownership.

You get full ownership of the source code, infrastructure, and documentation. No lock-in, no hidden fees.
