Why the top frontend app development team matters for your product
The frontend is what your users see and touch. A slow or buggy UI kills retention.
Every millisecond of load time reduces conversion rates. We optimize every component for Core Web Vitals, ensuring your app loads in under 2 seconds on 3G networks.
Accessibility is not an afterthought. We audit every page for WCAG 2.1 AA compliance, so your app works for users with disabilities and avoids legal risk.
How we differ from generic dev shops
Most agencies use junior developers and nickel-and-dime you for changes.
Generic dev shops assign junior developers who need training and produce inconsistent code. They bill hourly and add scope creep charges for every revision.
IRPR assigns senior engineers with 10+ years of experience. We give you a fixed price after the Roadmap phase and deliver a production-ready app in 8-12 weeks.
- Junior developers with 0-2 years experience
- Hourly billing that inflates costs
- No dedicated QA or accessibility testing
- Risky timeline with no fixed deadline
- Repositories held hostage until final payment
- No performance optimization work
- Senior engineers with 10+ years experience
- Fixed price from the Roadmap phase
- Dedicated QA engineer and a11y audits
- 8-12 week timeline with clear milestones
- Full code ownership from day one
- Core Web Vitals optimization included
Our process for building your frontend app
We follow a repeatable 4-phase framework to guarantee speed and quality.
The Idea phase is a 1-week deep dive where we map user flows and wireframes. You get a clear vision before any code is written.
The Roadmap phase produces a fixed-price quote and a 12-week plan. Every sprint ends with a deployable demo that you can test on real devices.
What ships with your frontend app
We don't just hand over code. You get a production-ready system.
Every project includes CI/CD, error tracking, accessibility reports, and documentation. You can deploy updates immediately after handover.
- Source code in a private GitHub repository
- CI/CD pipeline with GitHub Actions and Vercel/Netlify
- Sentry error tracking and performance monitoring
- Storybook component library with visual regression tests
- WCAG 2.1 AA accessibility report
- PageSpeed Insights report with scores over 90
- Admin documentation and environment setup guide
- Design file handoff (Figma or Sketch)
- Unit and integration tests with 80%+ coverage
- 2-week warranty for any post-launch bugs
