Why a dedicated frontend app development agency matters
Your frontend is what your customers see and touch. It must be fast, accessible, and maintainable.
A generic dev shop might hack together a UI with Bootstrap and call it done. But a dedicated frontend agency like IRPR builds for performance from day one. We use Next.js for SEO, React for interactivity, and TypeScript to catch errors before they ship. Every component is tested with Jest and Cypress, and accessibility is verified with axe DevTools.
Our frontends average a Lighthouse score of 95+ on mobile. We bundle code with Webpack or Vite, lazy-load routes, and compress images for sub-second load times. For clients with 500,000+ monthly visitors, we set up server-side rendering and CDN caching with Cloudflare. The result is a frontend that converts 40% better than the old one on average.
Generic dev shop vs IRPR frontend agency
Not all agencies build frontends the same way. Here is what sets IRPR apart.
Hiring a generalist agency for frontend work often leads to bloated code, slow load times, and no component library. They might use an outdated framework or skip accessibility checks. IRPR on the other hand starts every project with a design system and a performance budget.
We ship with automated visual regression testing, right-to-left language support, and a full Storybook component catalog. Every frontend we build is documented for your team to extend. The code is yours — hosted on GitHub in your own repository.
- Uses one framework for everything
- No performance budget or Lighthouse target
- Accessibility is an afterthought
- No design system or component library
- Hours-based billing with scope creep
- Code is not documented
- Chooses React, Vue, or Next.js based on your use case
- Sets a sub-3-second load target on 3G
- WCAG 2.1 AA compliance built in
- Delivers a Storybook component library
- Fixed price with clear scope in Roadmap phase
- Full documentation and code ownership
Our frontend development process
From idea to release, we follow a repeatable 4-phase process.
Phase 1 (Idea) takes 1 week. We align on requirements, create user flows, and choose the tech stack. Phase 2 (Roadmap) takes 1 week. We write a fixed-price proposal with UI mockups, component breakdown, and timeline.
Phase 3 (Product) takes 8-12 weeks. Two-week sprints deliver a working frontend with CI/CD, automated tests, and staging deployments. Phase 4 (Release) takes 1 week. We deploy to production, set up monitoring with Sentry, and hand over the codebase.
What ships with every frontend project
Every frontend we build includes these deliverables by default.
We don't just deliver code. We deliver a complete frontend system that your team can own and extend. This includes a component library, documentation, and a CI/CD pipeline.
Every project also comes with a performance report, accessibility audit, and a deployment runbook. You get the same quality whether you are a startup or a Fortune 500 company.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions and Vercel/Netlify
- Storybook component library with all states
- Unit tests with Jest and integration tests with Cypress
- Lighthouse report with 95+ scores
- WCAG 2.1 AA compliance report
- Sentry error and performance monitoring
- Deployment runbook and API documentation
- Design system tokens in JSON for export to Figma
- Webpack or Vite configuration for production builds
