Why Choose a Top React.js Development Agency
React.js is the most popular frontend framework with 40% of developers using it (Stack Overflow 2023).
A top React.js development agency like IRPR brings senior engineers who have shipped over 200 products. We use React.js 18, Next.js 14, and TypeScript by default. Every project follows a structured roadmap with code reviews and automated testing.
You get a fixed price, a clear timeline, and full ownership of the source code. No hourly billing, no scope creep. We integrate with your existing tools like HubSpot, Salesforce, or Stripe in the first 2 weeks.
How IRPR Differs from Other React.js Agencies
Most agencies sell hours and hope. IRPR sells a fixed outcome with a guaranteed timeline.
Generic dev shops often assign junior developers and charge by the hour. They change scope and add costs. You never know when the project will ship or how much it will really cost.
IRPR works differently. We assign senior React.js engineers only. We give you a fixed price after a 2-week Roadmap phase. We ship in 8-12 weeks. Every line of code is yours.
- Hourly billing with no cap
- Junior or mid-level developers
- No dedicated project manager
- Scope creep with extra costs
- No code ownership guarantee
- Average 6+ month delivery
- Fixed price from the start
- Senior engineers only (7+ years)
- Dedicated PM on every project
- Clear roadmap with no surprises
- Full source code ownership
- 8-12 week delivery
Our React.js Development Process
We follow a 4-phase process: Idea, Roadmap, Product, Release. Each phase has clear deliverables.
Phase 1 (Idea) takes 1 week. We align on goals, user stories, and tech stack. Phase 2 (Roadmap) takes 1 week. You get a detailed plan with wireframes, architecture diagram, and fixed price.
Phase 3 (Product) takes 6-10 weeks. We build in 2-week sprints with demos every Friday. Phase 4 (Release) takes 1 week. We deploy to production, set up monitoring, and hand off all code.
