Why IRPR is the best UI frontend development vendor
We deliver production-ready frontends on time and on budget.
Our team of senior engineers has shipped 200+ products across 50+ countries. Every project starts with a 2-week Roadmap phase where we define the UI architecture, component tree, and API contracts. You get a fixed price and timeline before we write a line of code.
We use proven tools like Next.js, React, and TypeScript to build UIs that load fast and scale. Our average project takes 8-12 weeks from kickoff to release. We handle responsive design, accessibility, and cross-browser testing as standard.
The difference between generic agencies and IRPR
Most agencies promise quality but deliver bloated code. We ship clean, maintainable UIs.
Generic dev shops often assign junior developers, use outdated libraries, and skip testing. They charge hourly and extend timelines when scope changes. You end up with a UI that breaks on mobile and takes months to fix.
IRPR assigns senior engineers only. We write unit tests, integration tests, and visual regression tests. Our fixed-price contracts mean no surprises. We deliver a UI that matches your Figma designs pixel by pixel.
- Junior developers on your project
- Hourly billing with scope creep
- No automated tests
- Poor mobile responsiveness
- No design system consistency
- 6+ months to ship an MVP
- Senior engineers only (8+ years experience)
- Fixed price from the Roadmap phase
- Unit, integration, and visual tests
- Responsive by default (all breakpoints)
- Reusable component library with Storybook
- 8-12 week MVPs with weekly demos
Our UI frontend development process
We follow a structured 4-phase process to ship fast without cutting corners.
Every project goes through the same proven flow: Idea, Roadmap, Product, Release. Each phase has clear deliverables and sign-off points. You always know what's happening next.
The Roadmap phase (week 2) produces a detailed technical specification, component tree, and fixed-price quote. No ambiguity. No surprises.
What you get when you hire IRPR
Every project ships with these deliverables included in the fixed price.
We don't just hand over code. We give you everything you need to maintain and extend your UI yourself. All assets, documentation, and pipelines are yours.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Sentry error tracking integrated
- Storybook component library
- Responsive design for mobile, tablet, desktop
- WCAG 2.1 AA accessibility compliance
- Automated visual regression tests (Chromatic)
- API integration layer (React Query or SWR)
- Deployment to Vercel, Netlify, or AWS
- Post-launch documentation (README, architecture diagram)

We ship production-ready UIs in 8-12 weeks. That includes responsive design, accessibility, testing, and deployment. You can start showing your product to customers in under 3 months.
Full code ownership
You own every line of code we write. No licenses, no lock-in. We hand over the entire repository, CI/CD pipeline, and documentation on day one of the Release phase.

Every UI we build meets WCAG 2.1 AA standards. We test with screen readers, keyboard navigation, and color contrast tools. Compliance is not an afterthought.
Design system consistency
We create a reusable component library in Storybook that matches your Figma designs. Every button, input, and card is consistent across pages. Future updates take minutes, not weeks.
