React frontends built for performance
Every React frontend we ship is optimized for speed, SEO, and user experience.
IRPR uses Next.js with static generation and incremental static regeneration to achieve sub-second page loads. We run Lighthouse audits on every build, targeting scores above 95 for performance, accessibility, and best practices.
Our React apps handle millions of requests per day. We integrate Sentry for error tracking, Google Analytics for user behavior, and A/B testing frameworks like LaunchDarkly for continuous improvement.
The difference between generic dev shops and IRPR
Not all React agencies deliver the same quality. Here is how we compare.
Most agencies bill hourly, hand off code with no CI/CD, and assign junior developers. IRPR gives you a fixed price, a dedicated senior team, and a production-ready app with full code ownership.
We transparently share our Roadmap in week 2. You see every sprint, every ticket, and every decision. No hidden scope, no surprise invoices.
- Hourly billing with no cap
- Junior or mixed-skill teams
- No dedicated UI/UX designer
- Slow iterations, long approval cycles
- Code stays with the agency
- No CI/CD or testing setup
- Fixed price quoted in week 2
- Senior React engineers only (5+ years)
- Senior designer on every project
- 2-week sprints, daily standups
- Full code ownership on day one
- Automated CI/CD with GitHub Actions
How we build your React frontend in 12 weeks
Our process is designed for speed and clarity.
We start with a 1-week Discovery phase where we map user flows, data models, and design system. You get a detailed Roadmap and a fixed price by week 2.
The Development phase runs in 2-week sprints. You review demos every sprint and we deploy to staging. Launch happens after final QA and performance tuning.

You get more than a UI. These are the deliverables included by default.
Every IRPR project includes source code, CI/CD, monitoring, and documentation. No line items, no add-ons. Everything here is included in your fixed price.
