Why hire a professional frontend app development agency?
A professional frontend app development agency ensures your app performs, scales, and converts.
Generic freelancers often produce code that bleeds memory, fails on slow networks, and ignores accessibility guidelines. IRPR builds every frontend with automated testing, performance budgets, and WCAG 2.1 AA compliance baked in from day one.
Our clients avoid costly rewrites. With 200+ products shipped across 50 countries, we deliver frontends that load in under 2 seconds on 3G and pass Lighthouse scores above 90.
How IRPR differs from other frontend agencies
Not all frontend developers deliver production-grade code. Here is the real difference.
Many agencies rush design and skip testing, leaving you with a fragile app that breaks on the next browser update. IRPR treats frontend engineering as a discipline, not a commodity.
We use Next.js or Nuxt.js for SSR, write unit tests with Jest and Vitest, and implement E2E tests with Playwright. Every project includes automated Lighthouse CI to keep performance scores high.
- Uses outdated jQuery or plain JavaScript
- No automated testing (manual only)
- Ignores accessibility (no ARIA, no keyboard nav)
- Slow load times due to unoptimized bundles
- No design system; inconsistent UI
- No performance monitoring after launch
- React, Next.js, Vue, Nuxt with TypeScript
- Unit tests (Jest) + E2E tests (Playwright)
- WCAG 2.1 AA compliance built in
- Code splitting, lazy loading, image optimization
- Storybook design system with live documentation
- Sentry error tracking and Lighthouse CI ongoing
Our frontend development process: from idea to deployed app
We follow four phases to turn your idea into a production frontend app within 12 weeks.
Every project starts with a two-week Roadmap phase where we define the user flows, component hierarchy, and tech decisions. This gives you a fixed price and a concrete timeline before a single line of code is written.
After that, we sprint through design prototypes, development, and testing. Deployment includes CI/CD via GitHub Actions, environment variables management, and a DNS setup.
What ships when you hire IRPR as your frontend agency
Every project delivers more than just code. Here is exactly what you receive.
- Full source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions (test + deploy)
- Figma design files with component library
- Storybook documentation for every reusable component
- Unit tests (Jest + React Testing Library)
- E2E tests (Playwright covering 5 key flows)
- Lighthouse performance report (target 90+)
- Sentry error tracking integration
- Environment variable management (dev/staging/prod)
- One month of post-launch support and bug fixes

Why teams hire us.
Fixed price, not hourly billing
Every project gets a fixed quote after the two-week Roadmap phase. No surprises, no hourly tracking. You know exactly what you pay from week 2 onward.
Senior engineers only, no juniors
We hire no junior developers. Every engineer on your project has 5+ years of frontend experience and ships production code daily. Average tenure at FAANG or top startups.
12-week delivery guarantee
We design processes to ship a working MVP in 12 weeks or less. If we miss the date, you pay nothing for the extra week. This has happened 0 times in 200+ projects.
Accessibility by default, not an afterthought
Every component is built to WCAG 2.1 AA standards from the first sprint. We test with screen readers, keyboard navigation, and color contrast analyzers. No remediation costs later.
Full code ownership with no lock-in
You own every line of code, every design file, and every account. We deploy to your infrastructure. No proprietary runtime or IP clauses. You can walk away with everything.
Post-launch monitoring and support
We include one month of post-launch support with Sentry error tracking and uptime monitoring. If something breaks, we fix it within 24 hours. Extended support available at $2,500/month.
Idea → Roadmap → Product → Release.
