You need senior engineers who deliver fast. We ship production React frontends in 12 weeks.
IRPR is a senior react frontend development agency. Our engineers work full-time in React 18, TypeScript, Next.js 14, and Tailwind CSS. Every project starts with a clear architecture using React Server Components, state management with Zustand, and automated testing with Playwright.
We ship a production-ready React frontend in 8 to 12 weeks. Fixed pricing starts at $80,000 and ranges up to $250,000 for complex enterprise apps. Every project includes CI/CD, Sentry error tracking, and a fully owned codebase.
Who hires us: CTOs of Series A SaaS companies who need a frontend that handles 100,000+ users. Product managers at healthcare startups who require HIPAA-compliant UI. Engineering leads at fintech firms who demand PCI-DSS ready interfaces. And e-commerce directors who want a headless storefront on Next.js.
Full client-side React app with lazy loading and code splitting. Integrates with REST or GraphQL backends like Hasura or Apollo.
Admin panels with complex data tables, real-time charts (Recharts), and multi-role access. Often paired with Auth0 or Clerk.
Live dashboards using WebSockets or Supabase Realtime. Renders thousands of data points with D3.js and React-window.
Headless storefront on Next.js with dynamic products, cart, and checkout. Integrates Stripe, Shopify Storefront API, or Commerce.js.
Multi-tenant UI with subscription management, billing history, and user roles. Built with React Admin or custom MUI components.
Offline-capable React app with service workers, push notifications, and app-like navigation. Uses Workbox or Next.js PWA plugin.
Pixel-perfect mobile UI with bottom navigation, gestures, and touch interactions. Tested on real devices via BrowserStack.
Reusable React components with Storybook, design tokens, and accessibility (WCAG 2.1 AA). Versioned and published to npm.
Hiring an agency of senior React engineers avoids the risk of junior developers and slow delivery.
IRPR only employs senior engineers with 6+ years of React experience. Our team averages 10 years of frontend work. We have shipped React frontends for 200+ products across 50 countries. Every engineer has contributed to production apps handling 1M+ monthly active users.
We use TypeScript by default, write unit tests with Vitest, and run end-to-end tests with Playwright. Our deployments use Vercel or AWS Amplify with automatic rollbacks. Code is reviewed by two senior peers before merge. No code reaches production without passing an automated test suite.
Most agencies mix junior and senior talent. IRPR assigns only senior React engineers from day one.
We have seen projects where a generic dev shop assigns a single mid-level developer to build the entire frontend. The result is inconsistent code, poor state management, and weeks of rework. Often they use outdated patterns like class components or Redux with too much boilerplate.
IRPR builds with React 18 functional components, custom hooks, and modern caching (React Query or SWR). Every project gets a dedicated senior engineer who architects the frontend before writing a single line of code. We deliver a production-grade app with 80% test coverage and a full CI/CD pipeline.
We follow a phased approach that de-risks your project from week one.
Every engagement starts with a 1-week Roadmap phase. We define user flows, component tree, API contracts, and a detailed time estimate. You pay a fixed fee of $5,000 for the Roadmap. If you move to build, that fee is deducted from the total.
After the Roadmap, we build in 2-week sprints. You see a working React app after the first sprint. We deploy to a staging environment on Vercel with automatic previews for every pull request. You give feedback on a real app, not static mockups.
You get a production-ready React frontend with everything needed to run and maintain it.
Every project includes the full source code, a private npm registry for shared components, and a style guide in Storybook. We also ship a deployment pipeline that builds, tests, and deploys to your cloud account. No black boxes.
We also provide a handover document that explains the architecture, state management decisions, and how to add new features. Your developers can start contributing within a day. We offer 30 days of post-release support at no extra cost.

Delivered a FERPA-compliant LMS frontend with drag-and-drop course builder, video streaming, and quiz engine. Course creation time dropped from 3 days to 2 hours. Stack: Next.js, TypeScript, Mux, Tailwind CSS.
Every engineer on your project has 6+ years of React experience. We don't hire juniors. You get a senior frontend architect who writes code, not just a manager who delegates.
We give you a fixed price after the Roadmap phase (week 2). No surprises. If we find new requirements, we adjust scope, not your budget.
From kickoff to production deploy in 12 weeks on average. We ship after the first sprint and keep deploying every two weeks. You see progress in real time.
You own every line of code we write. No proprietary frameworks, no lock-in. We push to your repository day one. You can fire us and keep everything.
We have built React frontends for HIPAA (healthcare), PCI-DSS (fintech), SOC 2 (SaaS), and FERPA (edtech). Our engineers know how to handle auth, audit logs, and data encryption.
Our portfolio proves we can deliver for any market. We have built for startups in New York, enterprises in London, and government agencies in Singapore. We work async-first with overlap hours.
Every engagement runs through the same four-stage pipeline. Predictable by design.
30-minute discovery call. No deck. We'll tell you honestly what it takes, how long, and how much.
