Experienced React Frontend Development CompanyDevelopment Company
We build complex React frontends for SaaS, fintech, and ecommerce. Senior engineers deliver production-ready UIs in 8-12 weeks.
IRPR builds React frontends for demanding applications. We use Next.js, TypeScript, React Query, and Tailwind CSS to ship production-level code.
We ship a complete, deployable React frontend in 8 to 12 weeks. Pricing is fixed from $80K to $250K based on scope. Every project passes accessibility audits and performance budgets.
We work with CTOs at Series A SaaS companies, product managers at fintech startups, heads of engineering at ecommerce brands, and founders building MVPs for investor demos.

Why React frontend expertise matters
A slow interface costs you users and revenue.
Every second of load time reduces conversion by 7%. Our React frontends consistently score over 90 on Lighthouse. We optimize bundle size, use code splitting, and lazy load images.
Accessibility is not an afterthought. We run axe-core tests in CI and ensure WCAG 2.1 AA compliance. Your application reaches more users and avoids legal risk.
Generic dev shops vs IRPR
Most agencies ship fragile React code that breaks when you scale.
Many companies waste months on rework after hiring the wrong team. They get junior developers, unclear requirements, and code that fails audits.
IRPR starts with a Roadmap phase that defines every screen, API call, and performance target. You get a fixed price and a senior team that delivers on schedule.
- Unclear requirements upfront
- Hourly billing inflates budget
- Junior devs learning on your dime
- No performance testing
- Code with no TypeScript
- No CI/CD from day one
- Fixed price after Roadmap phase
- Senior engineers in demand
- TypeScript and strict linting
- Performance budgets per page
- Automated accessibility checks (axe)
- CI/CD with GitHub Actions from week 1
Our React frontend delivery process
We move from concept to deployed frontend in phases.
Every project begins with a one-week Roadmap where we define routes, state management, design tokens, and API contracts. You receive a fixed price before development starts.
We then build in two-week sprints with demo reviews. By week 12 you get a production-ready application deployed to your infrastructure with full documentation.

Why teams hire us.
Fixed price from the start
We quote a fixed price after the Roadmap phase (week 2). No hourly billing, no surprise overages. Our 200+ projects all used fixed pricing.
Senior engineers, not juniors
Every developer has 7+ years of experience. We do not offshore or staff projects with junior devs. Your lead engineer stays through delivery.
TypeScript and strict linting
We configure TypeScript strict mode and ESLint from day one. This catches errors before runtime and keeps code consistent.
Performance built in
We set Lighthouse budgets for every page. Our UIs consistently score 90+ on performance and accessibility. We use React.memo and lazy loading by default.
Full code ownership
You get all source code, documentation, and deployment scripts. There is no lock-in. You can take over maintenance or hire your own team.
On-time delivery guarantee
98% of our projects ship on time. We use 2-week sprint cycles with demo reviews so nothing is hidden. We adjust scope before it's too late.
