Why choose an expert UI frontend development agency
IRPR delivers frontend projects that combine speed, quality, and accessibility.
With 200+ products shipped across 50+ countries, IRPR has the track record to prove it. Our team averages 10+ years of experience per engineer, and we maintain a 98% on-time delivery rate across all projects.
Every frontend we build is tested against WCAG 2.1 AA and passes Lighthouse performance audits. We use TypeScript and automated testing to make sure your interface works without regression.
The difference between generic dev shops and an expert UI frontend development agency
Not every agency builds frontend the same way. Compare the experience.
Generic shops often skip design systems, ignore accessibility, and produce code that is hard to maintain. They work on hourly billing and rarely deliver on time.
IRPR follows a structured process with a fixed price, a dedicated senior team, and a clear spec. We build for the long term with modular code and full documentation.
- Unclear requirements
- Slow communication
- No design system
- Average accessibility
- No automated testing
- Bloated code
- Detailed spec in 2 weeks
- Daily standups
- Design system from day one
- WCAG AA compliance
- Cypress test suite
- Modular architecture
Our frontend development process
We break every project into four phases with clear milestones.
Each phase is designed to reduce risk and keep you informed. You see working prototypes early and can provide feedback at every step.
IRPR uses Jira and weekly sprint reviews so you always know the project status.
