Senior Frontend Web Development PartnerSenior Frontend
You need a frontend partner that ships fast and ships right. IRPR builds production-grade UIs with React, Next.js, and TypeScript in as little as 12 weeks.
IRPR is a senior frontend web development partner. We build user interfaces with React, Next.js, TypeScript, and Tailwind CSS. Every project is led by an engineer with 10+ years of experience, not a junior or a project manager.
We ship production-ready frontends in 12-14 weeks for a fixed price of $80K-$250K. You get a design system, component library, unit tests, and a CI/CD pipeline. Compliance standards like HIPAA, PCI-DSS, and SOC 2 are built in from day one.
Companies with complex UIs hire us: CTOs at series A startups who need a scalable frontend without hiring a full team; product managers at mid-market firms who want a senior frontend web development partner to refactor legacy React code; and agency owners who need white-label frontend engineering for their clients.

Why you need a dedicated senior frontend web development partner
A generic dev shop delivers boilerplate. A senior frontend partner delivers an architecture that scales from day one.
Junior developers create code that works today but breaks in three months. Senior engineers at IRPR use patterns like compound components, render props, and state machines in XState. Every pull request is reviewed for bundle size, accessibility, and test coverage.
We have shipped 200+ frontend projects across 50 countries. Our clients see a 40% reduction in bug reports after the first release because we enforce TypeScript strict mode and 90% unit test coverage. We use Playwright for end-to-end tests on every page.
You get a partner who writes code that passes SEC, HIPAA, and PCI-DSS audits. We server-side render critical pages for SEO and use Suspense for progressive loading. No junior devs ever touch your codebase.
How IRPR compares to hiring freelancers or a general agency
The difference is predictability. Fixed scope, fixed price, senior engineers only.
A freelancer might disappear for two weeks. A general agency assigns one junior to your project and bills by the hour. IRPR puts a senior frontend architect on every engagement. You get a clear Roadmap in week 2 with a fixed quote.
We do not use offshore juniors. Every IRPR engineer is based in North America or Europe with overlapping working hours. Our async-first workflow means you get daily updates and a GitHub PR every 2-3 days.
- Assigns junior devs to keep margin high
- Bills hourly with no ceiling
- Uses outdated React patterns (class components)
- Ignores accessibility (WCAG)
- No CI/CD pipeline setup included
- Leaves no documentation or design system
- Senior frontend engineers only (10+ years)
- Fixed price from Roadmap phase (week 2)
- Modern stack: Next.js 14, React Server Components, TypeScript
- Built-in WCAG 2.1 AA compliance and keyboard navigation
- End-to-end CI/CD with GitHub Actions and automated Lighthouse checks
- Ships a Storybook design system and full component documentation
Our process: Idea to production frontend in 12 weeks
Every senior frontend web development engagement follows a four-phase process.
Phase one is the Roadmap. In week 2, you get a fixed quote, a component tree, and a timeline. Phase two is the Product build. Senior engineers code your design system and pages in parallel sprints.
Phase three is Release. We deploy to staging, run accessibility audits, and load test with k6. Phase four is Handoff. You get the full repo, CI/CD pipelines, and a 30-day support window.
What ships with every senior frontend engagement
You get more than code. You get a production-ready system that your team can maintain.
Every project includes a Figma-linked design system in Storybook, a test suite with Jest and Playwright, and a CI/CD pipeline that runs linting, type checking, and Lighthouse scores on every commit. We never ship without 90% component coverage.
You also get a deployment guide, environment variable templates, and a monitoring setup with Sentry error logging. The frontend is fully owned by you from day one.
- Source code in your private GitHub repository
- CI/CD pipeline with GitHub Actions + Vercel/Netlify deploy
- Storybook component library with MDX documentation
- Automated accessibility tests (axe-core, Lighthouse CI)
- Playwright end-to-end tests for all critical paths
- Design token file (JSON) linked to Figma
- Sentry error tracking configured
- Bundle size report (Webpack Bundle Analyzer)
- README with architecture decisions and local setup instructions
