Why choose IRPR as your premium UI frontend development vendor
We deliver frontend systems that last. Here is what our track record looks like.
IRPR has shipped over 200 frontend projects for clients in 50+ countries. Our engineers average 10+ years of experience and focus exclusively on React and TypeScript. Every project passes automated accessibility audits and visual regression tests.
We use a fixed-price Roadmap phase (week 2) to lock scope, timeline, and cost. Changes after that are priced transparently. No hourly billing, no scope creep, no surprise invoices.
Generic dev shop vs. IRPR
Most agencies treat frontend as a cost center. We treat it as a product.
Generic shops reuse boilerplate templates, assign junior devs, and bill by the hour. They often skip tests, accessibility, and performance budgets.
IRPR assigns senior engineers only, builds every component from scratch to match your design system, and delivers a fully tested, production-ready frontend with documentation and CI/CD.
- Hourly billing with scope creep
- Junior developers on your project
- No design system
- No accessibility audits
- No visual regression tests
- No documentation
- Fixed price locked in week 2
- 10+ year senior engineers
- Tokenized design system + Storybook
- WCAG AA compliance built in
- Playwright + Chromatic tests
- Full component documentation
How we build your premium frontend
Four phases, 8 to 12 weeks total. Here is the process.
Every project starts with a 2-week Ideation phase where we wireframe the UI and define component architecture. Then we move to Roadmap for scoping, fixed pricing, and tech choices.
The Build phase lasts 6–8 weeks with weekly demos. The Release phase includes deployment, load testing, and handing over full code ownership.
What ships with your frontend
You get more than code. Every project includes these deliverables.
All source code is placed in your private repository from day one. We set up GitHub Actions, Vercel deployments, Sentry error tracking, and a Storybook site with every component.
Design files in Figma are also transferred. You own the UX research, wireframes, and final mockups.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions + Vercel
- Storybook with live component library
- Sentry error tracking and performance monitoring
- Playwright end-to-end tests
- Chromatic visual regression tests
- Figma design files with tokens
- Accessibility report with WCAG 2.1 AA
- Lighthouse performance score 90+
- Internationalization setup (next-intl or similar)
