Why companies hire senior react development consultants
Building React apps that scale requires more than a junior developer. Here is what IRPR delivers.
IRPR has shipped over 200 React applications. Our senior react development consultants work with Next.js, TypeScript, and React Query to build apps that load in under 2 seconds and support 100,000 concurrent users. We set up error tracking with Sentry and performance monitoring with Lighthouse CI.
Every project includes a Roadmap phase (week 2) where we define the component tree, data flow, and deployment architecture. We use Storybook for component documentation and Cypress for end-to-end tests. The result is a codebase your internal team can maintain.
How IRPR differs from a typical react development agency
Most agencies assign juniors, bill hourly, and deliver late. IRPR does the opposite.
Generic dev shops often assign mid-level developers who learn React on the job. They bill hourly, so scope creep is common. They skip automated testing and deliver code without documentation.
IRPR assigns senior react development consultants with 7+ years of experience. We quote a fixed price in week 2. We ship with 90% test coverage, a CI/CD pipeline, and a Storybook component library. You get the source code and a deployment guide.

Our process for senior react development consulting
We move from idea to production in four phases. Each phase has a clear deliverable.
IRPR follows a structured process: Idea, Roadmap, Product, Release. Every phase has a fixed duration and a defined outcome. You review progress every two weeks.
The Roadmap phase (week 2) produces a detailed technical specification. The Product phase (weeks 3-10) includes two-week sprints with demos. The Release phase includes deployment, load testing, and documentation.
What ships with every senior react development project
You get more than code. Every project includes the assets your team needs to maintain and extend the app.
IRPR delivers a complete production system. You get source code, automated tests, CI/CD pipelines, and documentation. Every app is deployed to a production environment with monitoring and error tracking.
We also provide a Storybook component library, a Postman API collection, and a deployment guide. Your internal team can pick up the codebase and start shipping features within days.
- Source code in your GitHub repository
- CI/CD pipeline on GitHub Actions or Vercel
- 90%+ test coverage with Jest and Cypress
- Storybook component library with documentation
- Sentry error tracking and performance monitoring
- Postman collection for all API endpoints
- Deployment guide with environment variables and secrets
- 30-day post-launch support with 4-hour SLA
