Senior UI Frontend Development PartnerDevelopment Partner
Build pixel-perfect web interfaces with senior engineers who ship in 12 weeks. Flat rate from $80K.
IRPR is a senior-only software studio that builds UI frontend layers for web apps, design systems, and component libraries. We use React 18, TypeScript 5, Tailwind CSS 3, and Storybook 7 for every project.
Every engagement delivers a working frontend in 12 weeks at a fixed price between $80,000 and $250,000. We follow HIPAA, PCI-DSS, and SOC 2 compliance when needed.

Why Hire a Senior UI Frontend Development Partner

Generalist shops often deliver inconsistent UIs because they lack dedicated frontend specialists. Freelancers may disappear mid-project or use outdated tools.

How We Build Your Frontend
Four phases from idea to production UI.
Our process starts with a two-week Roadmap phase where we define the component tree, state management, and API contracts. After approval, we begin sprint cycles.
Each sprint delivers a deployable frontend with tests, documentation, and CI/CD. We use GitHub Actions for automated builds and Vercel or AWS for hosting.
What Ships With Every Project
You get more than just code.
Every frontend engagement includes a set of deliverables that let your team take over immediately. No black boxes.
Our checklist covers everything from source code to monitoring setup.
- Source code in your private GitHub repo
- Storybook component library with auto-generated docs
- TypeScript types for all API interactions
- Unit tests with Jest and React Testing Library (80%+ coverage)
- E2E tests with Playwright for critical user flows
- CI/CD pipeline on GitHub Actions with linting, testing, deploy
- Sentry error tracking and performance monitoring
- Vercel or AWS deployment with auto-scaling
- Figma token file for design to code parity
- 1-hour video walkthrough for your team
