Results that matter
Every frontend we deliver is measured against real-world performance and business outcomes.
Our team compiles every project with a focus on metrics: Lighthouse scores above 90, first input delay under 100ms, and 99.9% uptime after launch. These aren't goals we chase later—they're engineered from day one.
We've shipped interfaces for 200+ products across 50 countries. Our on-time delivery rate is 98%, and every codebase passes strict security and accessibility audits before handoff.
The IRPR difference
Most frontend agencies talk about quality. We build it into every contract, timeline, and line of code.
We don't do hourly billing or open-ended timelines. Every project gets a fixed price based on a detailed technical roadmap created in week two. You know exactly what you'll pay and when you'll ship.
Every developer on your project is a senior engineer with 7+ years of experience. No juniors, no training wheels. We write tests, enforce accessibility standards, and hand over a complete CI/CD pipeline.
- Hourly billing with no cap
- Junior developers assigned to reduce cost
- No dedicated QA or accessibility audits
- Code delivered as a ZIP file
- You manage deployments and hosting
- Scope creep causes 50%+ budget overruns
- Fixed price agreed in the Roadmap phase
- Senior engineers only (7+ years experience)
- Full QA, WCAG 2.1 AA, and Lighthouse score 90+
- Source code pushed to your GitHub repo
- CI/CD pipeline with Sentry and Datadog included
- Scope change process with transparent pricing
How we build your frontend
From concept to production, four phases keep the project on rails and on budget.
Every engagement follows our proven four-phase methodology. It starts with a discovery week where we align on UX, tech stack, and third-party integrations. You'll have a clear technical roadmap by week two.
Then we build and iterate in two-week sprints. You see working code every 14 days. The final phase is launch prep: load testing, accessibility audit, and CI/CD handoff. Total time: 8-12 weeks.
What ships with every frontend
You get more than a UI. You get a production-ready system with monitoring, testing, and documentation.
When we finish a project, we hand over everything you need to run, update, and scale the frontend yourself. No black boxes, no locked-in contracts.
- Source code in your private GitHub repository
- CI/CD pipeline using GitHub Actions
- Storybook component library with prop documentation
- Sentry error tracking and performance monitoring
- Lighthouse report with scores 90+ performance, accessibility, best practices
- WCAG 2.1 AA accessibility compliance report
- Unit and integration tests (Jest + React Testing Library)
- Responsive design tested on 200+ device/browser combinations
- Post-launch support SLA (24 hour response, critical bugs within 4 hours)
- Complete technical documentation including component API and deployment guide
