Why choose IRPR for top React.js development services
Our React.js team has shipped 200+ products across 50 countries with a 98% on-time record.
We use a structured four-phase approach: Idea, Roadmap, Product, Release. In the Roadmap phase (week 2), we deliver a fixed price quote and a detailed technical specification. No hourly billing, no surprises.
Every project includes CI/CD pipelines on GitHub Actions, Sentry error tracking, and automated testing. We deploy on Vercel, AWS, or your own infrastructure. Full source code is delivered to your repository.
What sets IRPR apart from other React.js development companies
Many agencies promise quality but deliver generic code and scope creep.
IRPR is different. We assign a team of senior React engineers (7+ years experience) to every project. You work directly with the developers who build your application. No account managers, no handoffs.
Our fixed-price model covers everything from design to deployment. The price you see in the Roadmap (week 2) is the price you pay. We absorb any additional work that would cause scope creep at other firms.
- Hourly billing with vague estimates
- Junior or offshore developers
- Scope creep without warning
- No dedicated QA process
- Deliver code only, no DevOps
- Hidden fees for integrations
- Fixed price from Roadmap phase (week 2)
- Senior engineers with 7+ years experience
- Scope changes discussed upfront, no surprises
- Automated testing and QA throughout
- CI/CD, Sentry, and monitoring included
- Full code ownership and transparency
Our React.js development process
We follow a four-phase methodology to deliver production-ready applications in 8-12 weeks.
Phase 1 (Idea) is a free discovery call. We review your requirements, target users, and tech constraints. Phase 2 (Roadmap) delivers a detailed spec with wireframes, user stories, and a fixed price quote.
Phase 3 (Product) is engineering. We build in two-week sprints with daily standups and weekly demos. Phase 4 (Release) includes deployment, documentation, and a 30-day warranty.
What ships with every React.js project
You get a complete production-ready application, not just code.
Every project includes automated testing (Jest, React Testing Library), CI/CD pipelines on GitHub Actions, and monitoring with Sentry. We also provide a deployment guide and a 30-day support window.
Optional services include load testing with k6, accessibility audits (WCAG 2.1 AA), and internationalization (i18n) for multi-language support.
- Source code in your private GitHub/GitLab repo
- CI/CD pipeline with GitHub Actions
- Sentry error and performance monitoring
- Automated tests (unit, integration, e2e)
- Responsive design for desktop, tablet, mobile
- SEO-friendly (Next.js SSR or static generation)
- Deployment guide and AWS/Vercel setup
- Docker configuration for local development
- API documentation (OpenAPI/Swagger)
- 30-day post-launch support and bug fixes
