Why hire professional UI frontend development consultants
Your frontend is the first thing users see. It must load fast, work on every device, and convert visitors into customers.
IRPR has shipped 200+ frontends for clients in 50+ countries. We use React, Vue.js, Angular, and TypeScript. Every project includes responsive design, accessibility (WCAG 2.1 AA), and a performance budget of under 3 seconds on 3G.
We write unit tests with Jest and integration tests with Cypress. We set up CI/CD with GitHub Actions so every pull request runs tests and deploys to staging. You get a frontend that works before you launch.
Generic dev shop vs professional UI frontend consultants
Not every agency can build a frontend that scales. Here is the difference between a generic shop and IRPR.
Generic shops often deliver bloated code, slow load times, and no tests. They use outdated libraries and ignore accessibility. You end up with a frontend that needs a rewrite in 6 months.
IRPR builds frontends that are fast, accessible, and maintainable. We use modern tooling like Vite, Tailwind CSS, and Zustand. Every component is documented in Storybook and tested with Cypress.

How we build your frontend in 12 weeks
Our process is transparent and fixed-price. You know the timeline and cost before we write a line of code.
Week 1-2: Discovery and design handoff. We review your Figma files, brand guidelines, and user flows. We create a component tree and define the tech stack (React, Vue, or Angular).
Week 3-10: Sprint-based development. We build components in Storybook, write tests, and deploy to staging every 2 weeks. You review and give feedback in real time.
Week 11-12: QA, performance tuning, and launch. We run Lighthouse audits, fix accessibility issues, and deploy to production. You get a frontend that passes Core Web Vitals.

You own everything. Source code, tests, documentation, and deployment pipeline.
Every project includes a complete delivery package. You get the code in your GitHub repo, a CI/CD pipeline, and a component library in Storybook. No black boxes.
We also provide a performance report, accessibility audit, and a style guide. Your team can pick up the code and continue building after we hand off.
