Why hire a senior UI frontend development firm
A senior frontend team delivers a polished, accessible, and maintainable UI that your users trust.
IRPR assigns 2-4 senior frontend engineers to every project. Each engineer has 8+ years of experience with React, Vue, or TypeScript. We do not use junior developers or offshore contractors. You get the same team from kickoff to deployment.
Our frontends pass WCAG 2.1 AA accessibility standards. We test with axe-core and Lighthouse. We also audit performance: our typical build achieves a 90+ Lighthouse score and a bundle size under 200KB (gzipped).
Generic agency vs senior UI frontend development firm
Not all agencies deliver senior-level frontend work. Here is how IRPR differs from a generic dev shop.
A generic agency might assign a junior developer to your project. They use pre-built templates and skip accessibility testing. Their code often has no automated tests and no design system. You end up with a fragile frontend that breaks on the next update.
IRPR builds every frontend from scratch with a custom design system. We write unit tests with Jest and Vitest, integration tests with Cypress, and accessibility tests with axe-core. We hand over full ownership of the code and documentation.

Our frontend development process
We follow a 4-phase process that moves from idea to production in 8-12 weeks.
Phase 1 is the Roadmap. In week 1, we audit your current frontend or wireframes. We produce a detailed technical specification with component tree, data flow, and route design. You get a fixed price and timeline at the end of this phase.
Phase 2 is the Build. We code the UI in React or Vue with TypeScript. We set up Storybook for component documentation, Jest for unit tests, and Cypress for integration tests. We deploy to a staging environment on Vercel or Netlify.
What ships with every frontend project
Every IRPR frontend project includes these deliverables by default.
You get more than a working UI. We ship a complete, documented, and tested frontend that your team can maintain. No black boxes, no missing pieces.
All code is delivered in a private GitHub repository. We set up CI/CD pipelines on GitHub Actions or Vercel. We also configure Sentry for error tracking and LogRocket for session replay.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions or Vercel
- Component library in Storybook with documentation
- Unit tests with Jest or Vitest (90%+ coverage)
- Integration tests with Cypress (critical user flows)
- Accessibility audit report (WCAG 2.1 AA)
- Lighthouse performance report (90+ score)
- Sentry error tracking configured
- Deployment guide and README
