Senior React Frontend Development ServicesDevelopment Services
We build React frontends that ship in 12 weeks. Your code, your repo, no hourly billing.
IRPR builds senior React frontend development services for companies that need production-grade user interfaces. We use React, TypeScript, Next.js, and Tailwind CSS to ship fast, accessible, and scalable frontends.
Every engagement starts with a 2-week Roadmap phase. After that, we build your frontend in 8-12 weeks with fixed pricing from $80K to $250K. You get full ownership of the code, CI/CD pipelines, and a dedicated senior engineer.
CTOs hire us when their in-house team lacks React depth. Startup founders use us to validate their product with a polished MVP. Product managers bring us in to rebuild legacy UIs without disrupting their roadmap.
Types of software we ship.
Single-page application (SPA)
Fast, dynamic UIs with React Router and state management via Redux or Zustand. No page reloads.
Server-side rendered app (SSR)
SEO-optimized React apps using Next.js or Remix. Pages render on the server for faster load times.
Static site generator (SSG)
Pre-built HTML pages with Next.js static export. Ideal for marketing sites and documentation.
Progressive web app (PWA)
React apps with service workers and offline support. Users install them on their home screen.

Why senior React frontend development services matter
A junior React developer can build a page. A senior React developer builds a system that scales, loads fast, and doesn't break.
Senior React frontend development services from IRPR focus on production-grade code from day one. We use TypeScript for type safety, Next.js for server-side rendering, and Tailwind CSS for consistent styling. Every component is tested with Jest and React Testing Library.
Our engineers have shipped over 200 products across 50 countries. They know how to handle edge cases, optimize bundle size, and set up error boundaries. You get a frontend that works on slow networks, old browsers, and screen readers.
What sets IRPR apart from other React shops
Most agencies bill by the hour and disappear after launch. IRPR gives you fixed pricing, a senior engineer, and full code ownership.
We have seen projects stall because the agency used junior developers or changed scope mid-build. IRPR assigns a senior React engineer who stays on your project from start to finish. No handoffs, no rotating staff.
Our fixed pricing model means you know the cost before we write a line of code. After the Roadmap phase (week 2), we quote the full build. If you add features, we quote the delta. No surprises.
- Hourly billing with no cap
- Junior or mid-level developers
- No dedicated engineer
- Code ownership unclear
- No CI/CD setup included
- Slow response to bugs
- Fixed price from $80K to $250K
- Senior React engineers only
- One engineer from start to end
- Full code ownership in your repo
- CI/CD pipeline with GitHub Actions
- Sentry error tracking included
How our senior React frontend development process works
We follow a 4-phase process: Idea, Roadmap, Product, Release. Each phase has clear deliverables and a fixed timeline.
Phase 1 (Idea) takes 1 week. We align on goals, user stories, and tech stack. Phase 2 (Roadmap) takes 1 week. We create a detailed plan with wireframes, component hierarchy, and a fixed price quote.
Phase 3 (Product) takes 8-12 weeks. We build the frontend sprint by sprint, with weekly demos and code reviews. Phase 4 (Release) takes 1 week. We deploy to production, set up monitoring, and hand over the repo.
What ships with every React frontend project
Every engagement includes these deliverables by default. No hidden costs or optional add-ons.
We believe in full transparency. When we finish a project, you own everything: the source code, the design files, the CI/CD pipeline, and the monitoring setup. Nothing is locked behind a license or a retainer.
- Source code in your GitHub repo
- CI/CD pipeline with GitHub Actions
- Sentry error tracking
- Google Analytics or Plausible setup
- Responsive design for mobile, tablet, desktop
- Accessibility audit (WCAG 2.1 AA)
- Unit tests with Jest and React Testing Library
- Storybook component library
- Deployment to Vercel or AWS
- 1 hour of post-launch support per week for 4 weeks
What we ship in this practice.
SaaS dashboard for a B2B analytics platform
Built a real-time dashboard with React, D3.js, and WebSockets. The client reduced page load time from 4 seconds to 1.2 seconds. Used Next.js for SSR and PostgreSQL for data storage.
Ecommerce storefront for a DTC brand
Developed a headless commerce frontend with Next.js and Shopify. Checkout conversion rate increased by 18%. Integrated Stripe for payments and Klaviyo for email marketing.
Telemedicine portal for a healthcare startup
Created a HIPAA-compliant patient portal with React and Twilio Video. Patients could schedule appointments and join video calls. The startup raised a $2M seed round after launch.
Investment dashboard for a fintech company
Built a PCI-DSS compliant dashboard with React and Chart.js. Users could view portfolios, execute trades, and download reports. The platform handles 10,000+ concurrent users.
Learning management system for an edtech firm
Developed a FERPA-compliant LMS with React and Next.js. Students could take quizzes, track progress, and chat with instructors. The client onboarded 5,000 students in the first month.
Property listing portal for a real estate agency
Created an MLS-integrated property search with React and Google Maps API. Agents could upload listings and schedule showings. The portal reduced manual data entry by 8 hours per week.
Why teams hire us.

Senior engineers only
We hire senior React engineers with 5+ years of experience. No juniors, no mid-levels, no rotating staff. Your project gets one dedicated engineer.
Full code ownership
You own the source code, the design files, and all configurations. We push everything to your GitHub repo. No proprietary frameworks, no lock-in.
Production-grade from day one
Every component is tested, accessible, and optimized. We use TypeScript, Jest, and React Testing Library. Your frontend passes Lighthouse audits and WCAG 2.1 AA.
8-12 week MVPs
We ship a working frontend in 8-12 weeks. You can start collecting user feedback and iterating. Our average MVP timeline is 12 weeks across 200+ products.
