Why IRPR is the best UI frontend development firm
We ship frontends that load fast, look consistent, and scale with your user base.
Our frontends score 90+ on Lighthouse performance audits. We use Next.js for server-side rendering, lazy loading, and image optimization. Every component is tested with Jest and Cypress before it reaches production.
We build design systems in Storybook so your team can reuse components across products. We support dark mode, internationalization (i18n), and accessibility out of the box. Our clients see a 40% reduction in UI bugs after launch.
How we differ from other frontend agencies
Most agencies bill hourly and hand off messy code. We do the opposite.
Generic dev shops often use junior developers, change scope mid-project, and deliver code without tests. You end up with a slow frontend that breaks on every browser update.
IRPR assigns senior engineers only. We give you a fixed price in week 2. We write unit tests, integration tests, and end-to-end tests. You get a CI/CD pipeline, error tracking with Sentry, and performance monitoring with Lighthouse CI.
- Junior developers with 1-2 years experience
- Hourly billing with no cap
- No automated tests
- No design system
- No CI/CD pipeline
- Code ownership unclear
- Senior engineers with 8+ years experience
- Fixed price from $80K to $250K
- 100% test coverage on critical paths
- Storybook design system included
- GitHub Actions CI/CD pipeline
- Full source code ownership
Our frontend development process
We follow a 4-phase process that turns your idea into a live frontend in 8-12 weeks.
Phase 1 is the Idea phase where we define user stories and wireframes. Phase 2 is the Roadmap phase where we lock scope and price. Phase 3 is the Product phase where we build and test. Phase 4 is the Release phase where we deploy and hand over.
You get weekly demos and a Slack channel with the whole team. We use Linear for task tracking and Figma for design handoff. Changes are scoped in the Roadmap phase so there are no surprises.

Every project includes these deliverables by default. No hidden costs.
We ship production-ready code that your team can extend immediately. All assets are in your GitHub repository from day one.
