Why choose a leading UI frontend development firm like IRPR
Your frontend is the first thing users see. A bad UI costs you users and revenue.
IRPR has shipped 200+ frontend projects across 50 countries. Our engineers average 10+ years of experience in React, Vue.js, Angular, and TypeScript. We follow strict code review processes and use automated visual regression testing (Percy, Chromatic) to catch pixel-level bugs before they reach production.
We start every engagement with a two-week Roadmap phase. During that time we audit your existing code, define the component tree, and produce a fixed-price quote. No surprises. No hourly billing. You get a clear timeline and a single point of contact.
The difference between IRPR and a generic dev shop
Not all frontend teams are equal. Here is what sets a leading firm apart.
Generic dev shops often assign junior developers to your project. They use outdated libraries, skip accessibility, and deliver code that breaks in the next browser update. You end up paying for rewrites and bug fixes.
IRPR assigns a senior frontend engineer from day one. Every line of code is peer-reviewed. We use TypeScript, ESLint, Prettier, and automated testing (Jest, Cypress, Playwright). Your codebase is clean, documented, and ready to scale.
- Junior developers with limited experience
- No design system or component library
- Manual testing only, no CI/CD
- Accessibility ignored (WCAG failures)
- Unclear timelines and cost overruns
- No post-launch support or documentation
- Senior engineers with 10+ years experience
- Custom design system in Figma and Storybook
- Automated visual and unit tests in CI/CD
- WCAG 2.1 AA compliance built in
- Fixed price from the Roadmap phase
- Full documentation and 30-day post-launch support
Our frontend development process in 4 phases
We follow a repeatable process that de-risks your project and keeps you in control.
Every project starts with a discovery phase where we map user flows, wireframe key screens, and define the tech stack. Then we move into design, development, and release. You see working code every two weeks.
We use Agile sprints with daily standups and a shared Jira board. You can track progress in real time. No black boxes.
What ships with every frontend project from IRPR
You get more than code. You get a complete, production-ready system.
Every project includes a design system, a component library, automated tests, and deployment scripts. We also provide a style guide and a handover document so your internal team can take over easily.
All code is hosted in your own GitHub or GitLab repository from day one. You own everything.
- Source code in your private repository
- Design system in Figma with component tokens
- Storybook component library with interactive docs
- CI/CD pipeline (GitHub Actions or GitLab CI)
- Automated unit tests (Jest) and integration tests (Cypress)
- Visual regression tests (Percy or Chromatic)
- Sentry error tracking and performance monitoring
- WCAG 2.1 AA accessibility report
- Deployment scripts for AWS, Vercel, or Netlify
- 30-day post-launch support and bug fixes

Why teams hire us.
Fixed price, not hourly billing
Every project gets a fixed quote after the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write a line of code.
Senior engineers only, no junior staffing
Every engineer on your project has 10+ years of experience in frontend development. We do not outsource or staff juniors. Your code is written by experts.
Design system included with every project
We build a reusable component library in Storybook with Figma tokens. Your internal team can extend it without breaking existing UI. Saves weeks of future development time.
Accessibility built in, not bolted on
We test every component against WCAG 2.1 AA standards using axe-core and manual testing. Your app is usable by everyone, and you avoid legal risk.
Automated testing from day one
We write unit tests (Jest), integration tests (Cypress), and visual regression tests (Percy) for every component. Your codebase stays stable as it grows.
Full ownership of code and design assets
You own the source code, design files, and all deliverables. No licensing fees, no lock-in. You can take the project in-house or to another team at any time.
