Experienced React Frontend Development DevelopersFrontend Development
Senior React engineers build your custom UI in 12 weeks or less. Fixed price, no hourly billing.
IRPR builds custom React frontends for web apps, SaaS platforms, and data dashboards. We use React 18, TypeScript 5, Next.js 14, and Redux Toolkit. Every line of code is unit tested with Jest and Playwright for e2e coverage.
A typical frontend project ships in 8 to 12 weeks. Fixed pricing starts at $80,000 and goes to $250,000 for complex multi-role interfaces. We comply with HIPAA, PCI-DSS, SOC 2 type II, and GDPR.
Founders hire us to launch their SaaS MVP with a polished UI. CTOs engage us to rebuild legacy Angular or jQuery frontends in React. Product managers bring us in to add complex data visualizations with D3.js and real-time collaboration with WebSockets.

Why experienced React frontend development developers matter
A junior developer can build a button. An experienced team builds a system that scales, loads fast, and passes accessibility audits.
IRPR assigns senior engineers only. Every developer has at least 6 years of React experience. They have shipped production apps with 100,000+ daily users. They know how to structure components for maintainability, apply code splitting to reduce bundle size, and set up error boundaries to catch failures before they reach your users.
We use Lighthouse CI to enforce performance budgets. Our teams run on React 18 with concurrent rendering and automatic batching. Pages load under 2 seconds on 3G connections. Every pull request runs a full set of unit tests and visual regression tests using Chromatic.
How IRPR differs from a generic React agency
Generic shops reskill juniors and bill hourly. IRPR assigns senior engineers only on a fixed price.
When you hire a generic development shop for your React frontend, you often get junior or mid-level developers who learn on your dime. They write inconsistent code, miss accessibility standards, and fail to set up proper testing. The result is a UI that works on the demo but breaks in production.
IRPR assigns a team of senior React engineers with an average of 8 years of experience. We write a fixed price contract in week 2 after the Roadmap phase. You know the exact cost and timeline before we write a single line of code.
- Assigns junior developers with 1-2 years of React
- Bills by the hour, budget overruns are common
- No dedicated QA engineer on the team
- Code has no test coverage
- Uses outdated React patterns (class components, no hooks)
- No performance auditing before launch
- Senior React engineers with 6+ years experience
- Fixed price quoted in the Roadmap phase (week 2)
- Dedicated QA engineer writes Playwright e2e tests
- 100% unit test coverage on all components
- Uses React 18 with hooks, concurrent rendering, and TypeScript
- Lighthouse CI enforces sub-2-second load times
Our React frontend development process
We ship your UI in four clear phases. No ambiguity, no assumptions.
The process starts with a 1-week Idea phase where we align on goals and sketch the user journey. Then we move to a 1-week Roadmap phase where we write a detailed spec, a fixed price quote, and a timeline.
The Product phase is 8 to 10 weeks of iterative development. We build in 2-week sprints with demos at the end of each. The Release phase includes load testing, accessibility audits, and deployment to your production environment.
What ships with your React frontend
You get more than a working UI. You get a production-ready codebase with tooling, tests, and documentation.
Every React project from IRPR ships with a complete development environment. We set up ESLint, Prettier, Husky pre-commit hooks, and a CI/CD pipeline on GitHub Actions. The pipeline runs tests on every pull request and deploys to a staging environment automatically.
We also include user analytics with PostHog or Mixpanel, error tracking with Sentry, and performance monitoring with Lighthouse CI. Your team can take over maintenance with zero ramp-up.
- Source code in your private GitHub or GitLab repo
- CI/CD pipeline on GitHub Actions with automated tests and deployment
- Sentry error tracking for production monitoring
- PostHog analytics integration for user behavior tracking
- Storybook component library with visual regression tests using Chromatic
- Complete unit test suite with Jest and React Testing Library
- End-to-end tests with Playwright covering critical user flows
- Lighthouse CI report with performance, accessibility, and SEO scores
- Design system documentation (colors, typography, component props)
- 1-hour knowledge transfer session with your team

Why teams hire us.
Only senior React engineers
IRPR does not hire juniors. Every developer has at least 6 years of production React experience. Our team members have built apps for companies like Stripe, Airbnb, and Spotify.
Fixed price, not hourly
We give you a fixed price in week 2 during the Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges. If we add features, we quote them separately.
12-week MVP guarantee
Most React frontend projects ship in 8 to 12 weeks. We set a clear timeline and stick to it. If we miss, you get a discount on the next phase.
Production-ready code, not a prototype
We write tests, set up CI/CD, add error tracking, and run performance audits. Your team can take over the codebase immediately after we ship.
Compliance built in from day one
We have built React frontends for HIPAA, PCI-DSS, SOC 2, and GDPR environments. We know where to apply encryption, logging, and access control.
Clear communication across time zones
We work async-first with daily standups on Slack and weekly sprint demos. Our team overlaps with US time zones for at least 4 hours per day.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
