Why experience matters in UI frontend development
An experienced vendor ships faster with fewer bugs and better accessibility.
IRPR has shipped over 200 frontend projects across 50 countries. Our senior engineers average 10 years of experience. We deliver 98% of projects on time and maintain 99.9% uptime for our production UIs.
We handle complex animations, multilingual layouts, and strict accessibility standards. Every project passes WCAG 2.1 AA and OWASP top 10 checks before launch. Our clients reduce post-launch bugs by 40% on average.
Generic dev shop vs. IRPR as your UI frontend vendor
The difference is in the details: code quality, reliability, and ownership.
Most generic shops use a single framework with no design system and no testing. They revise scope mid-project and charge for overrun hours. The result is a fragile UI that needs constant patches.
IRPR treats every project as a product. We build with TypeScript, Storybook, and Playwright from day one. The code is yours, the design system is documented, and the project stays on budget.
- Uses React only, no TypeScript
- No design system or Storybook
- No automated testing
- Ignores accessibility (WCAG)
- Hourly billing with scope creep
- No post-launch support
- React + TypeScript + Storybook
- WCAG 2.1 AA compliance on every project
- CI/CD with Playwright E2E tests
- Figma-to-code in 48 hours
- Fixed price from $80K to $250K
- 6 months free bug fixes
Our UI frontend development process
We follow a repeatable process that delivers results in 8-12 weeks.
Every project starts with a Roadmap phase (week 2) where we define architecture, tech stack, and a fixed price. Then we split development into 2-week sprints with demos at the end of each sprint.
You get a working MVP in the first 4 weeks. We use automated checks for performance, accessibility, and security. The final handover includes full documentation and a 6-month warranty.
