Why companies choose IRPR for UI frontend consulting
Our track record speaks for itself.
We have shipped over 200 products across 50 countries, with 98% on-time delivery. Our senior engineers average 10+ years of experience with modern frontend frameworks.

The difference between generic dev shops and IRPR
Most agencies treat frontend as an afterthought. We treat it as the product.
Generic dev shops start coding without a design system. They skip accessibility, ignore performance budgets, and leave you with unmaintainable code.
IRPR builds a component library in week 1, enforces WCAG 2.1 AA, and ships automated visual regression tests. You get a frontend that scales.
- No design system or component library
- Accessibility ignored until audit
- Slow iterations with no CI/CD
- Unclear scope leads to budget overruns
- Code ownership often disputed
- No post-launch support
- Design system built in week 1 with Figma tokens
- WCAG 2.1 AA compliance by default
- 2-week sprint cycles with CI/CD
- Fixed price after 2-week Roadmap phase
- 100% code ownership transferred
- 2-week post-launch support included
