Why hire a senior react development company
Senior React developers ship faster, write cleaner code, and avoid costly rewrites.
Junior developers often create bloated components and miss performance optimizations. A senior React engineer knows when to use useMemo, how to structure state with Redux Toolkit or Zustand, and how to set up server-side rendering with Next.js. This means your app loads in under 2 seconds and scales to 100,000 users without crashing.
IRPR's senior engineers have shipped over 200 React applications across 50 countries. We follow a strict code review process, enforce TypeScript strict mode, and maintain 90%+ test coverage on critical paths. Every project includes a performance audit using Lighthouse and Web Vitals.
Generic agency vs senior react development company
Not all React agencies deliver the same quality. Here is the difference.
Many agencies assign junior developers to React projects to save costs. You pay $150/hour for a developer who learned React six months ago. The code is fragile, the tests are missing, and the app breaks after the first deployment.
IRPR assigns a senior React engineer as the technical lead from day one. Every developer has 7+ years of React experience. We use a fixed-price contract so you know the cost upfront. The code is yours, the tests are comprehensive, and the app is deployed to production with a CI/CD pipeline.
- Junior developers with 1-2 years of React experience
- Hourly billing with no cost cap
- No TypeScript or minimal type safety
- Manual deployment, no CI/CD
- No performance budget or Web Vitals tracking
- Code ownership unclear, often shared
- Senior React engineers with 7+ years experience
- Fixed price from $80K to $250K
- TypeScript strict mode on every project
- CI/CD pipeline on GitHub Actions from week 1
- Lighthouse score target of 90+ on all pages
- Full source code ownership, no strings attached
How we build your React application
Our process moves from idea to production in 12 weeks. No delays, no surprises.
Every project starts with a 2-week Roadmap phase. We define the architecture, choose the tech stack, and produce a fixed-price contract. You approve the scope before we write a single line of code.
The Product phase runs for 8-10 weeks. Our senior engineers work in 2-week sprints. You see a working demo at the end of every sprint. The Release phase includes load testing, security audit, and deployment to AWS or Vercel.
What ships with every React project
Every project includes these deliverables by default. No hidden extras.
We believe in transparency. Every project includes source code, CI/CD, monitoring, and documentation. There are no surprise costs for deployment or handover.
- Source code in your private GitHub repository
- CI/CD pipeline on GitHub Actions with automated tests
- TypeScript strict mode enabled across the codebase
- Unit tests with Jest and React Testing Library (90%+ coverage)
- End-to-end tests with Cypress for critical user flows
- Performance report with Lighthouse and Web Vitals
- Deployment to AWS, Vercel, or your preferred cloud
- Sentry error tracking and logging configured
- README with architecture overview and setup instructions
- Post-launch support for 30 days

Why teams hire us.
Senior engineers only, no juniors
Every developer on your project has 7+ years of React experience. We never staff juniors to save costs. Our team includes former engineers from Google, Microsoft, and Amazon.
Fixed price, not hourly
You get a fixed price quote after the 2-week Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges. The price is locked from week 2.
Full code ownership
You own 100% of the source code, design files, and documentation. We never license or reuse your code. You can take it to any other team after the project ends.
12-week delivery guarantee
We ship production-ready software in 12 weeks on average. 98% of our projects finish on time. If we miss the deadline, you pay nothing extra.
Built for scale and compliance
We design for HIPAA, SOC 2, and PCI-DSS compliance from day one. Your app is built on AWS or Azure with auto-scaling, database replication, and encrypted storage.
Proven track record with 200+ products
