Expert frontend development process
Our frontend team follows a proven 4-step process to ship your app.
We start with a 1-week Roadmap phase where we define the component tree, data flow, and design system. This gives you a fixed price and timeline before any code is written.
Then our senior engineers build the frontend in 2-week sprints, integrating with your backend and testing for performance and accessibility. You see progress every sprint.
Why generic agencies fail at frontend
Most dev shops deliver slow, buggy frontends that don't scale.
Generic agencies often assign junior developers who lack experience with modern frameworks. The result is a frontend that breaks on mobile, scores poorly on Lighthouse, and requires constant fixes.
IRPR only hires senior frontend engineers with 7+ years of experience. We use a modern stack, automated testing, and component libraries to deliver a frontend that works out of the box.
- No dedicated frontend architect
- Uses outdated tech like jQuery
- No performance optimization
- No accessibility compliance
- No component reusability
- No CI/CD for UI testing
- Senior frontend engineers only
- Modern stack: React, Next.js, TypeScript
- Lighthouse scores 90+
- WCAG AA compliance built-in
- Storybook component library
- Automated visual regression testing
What we deliver in your frontend MVP
Your frontend comes with everything needed to launch and scale.
We don't just hand over code. Every project includes a design system, documented components, and a deployment pipeline. You can immediately iterate and add features.
Our frontends are built to handle growth. We optimize for Core Web Vitals, set up error tracking with Sentry, and provide API integration examples so your backend team can start connecting right away.

When we deliver your frontend, you receive all assets needed to maintain and scale it yourself or with your team.
