Professional Frontend App Development PartnerDevelopment Partner
We build fast, pixel-perfect frontends for your product. 12-week MVPs, fixed price, no surprises.
IRPR is a professional frontend app development partner that builds modern user interfaces with React, Next.js, Vue.js, and TypeScript. Our senior engineers write clean, maintainable code that ships fast and scales without rewrites.
Every project starts with a 2-week Roadmap phase where we scope the UI, define component architecture, and lock the price. MVPs ship in 8-12 weeks, with pricing from $80K to $250K depending on complexity. We handle state management, API integration, responsive design, and accessibility (WCAG 2.1 AA).
Founders hire us when they need a polished frontend for their SaaS MVP. CTOs hire us to unblock their backend team with a dedicated UI squad. Product owners hire us to rebuild a legacy frontend in React or Vue without downtime.

Why a professional frontend app development partner matters
Your frontend is what users see and touch. A bad UI kills adoption, no matter how good your backend is.
IRPR has shipped 200+ frontend projects across 50 countries. Our senior engineers use React, Next.js, and TypeScript to build interfaces that load fast, work on every device, and pass WCAG 2.1 accessibility audits. We integrate with any backend via REST or GraphQL.
We start every engagement with a 2-week Roadmap phase. You get a component tree, a tech stack decision log, and a fixed price before we write a line of production code. No hourly billing, no scope creep, no surprises.
How IRPR differs from a generic dev shop
Most agencies bill hourly and hand off messy code. IRPR gives you a senior team, fixed price, and full ownership.
Generic dev shops assign junior developers who learn on your dime. They use outdated tech, skip testing, and deliver bloated bundles that hurt Lighthouse scores.
IRPR assigns senior engineers with 8+ years of experience. We write TypeScript, use React Query for data fetching, and ship with CI/CD, Sentry error tracking, and automated visual regression tests. Every project includes a performance budget and a Lighthouse score target.
- Junior devs learning on your project
- Hourly billing with no cap
- No TypeScript, no tests
- Manual deploys, frequent downtime
- No performance or accessibility audits
- You own nothing, code is locked
- Senior engineers with 8+ years experience
- Fixed price locked in week 2
- TypeScript, unit tests, E2E tests
- CI/CD with GitHub Actions, 99.9% uptime
- Lighthouse score 90+ and WCAG 2.1 AA
- Full code ownership, no lock-in
Our frontend development process
We follow a 4-phase process that turns your idea into a production-ready frontend in 8-12 weeks.
Phase 1 (Idea) is a free discovery call where we map your requirements to a tech stack and timeline. Phase 2 (Roadmap) is a 2-week sprint where we design the component tree, write technical specs, and lock the fixed price.
Phase 3 (Product) is the build: 6-10 weeks of sprint cycles with daily standups, weekly demos, and continuous deployment. Phase 4 (Release) includes load testing, accessibility audit, and handoff with full documentation.
What ships with every frontend project
Every delivery includes more than just code. You get production-grade infrastructure, documentation, and full ownership.
We set up your project from day one with a monorepo, ESLint, Prettier, and Husky pre-commit hooks. Every component is typed with TypeScript and documented in Storybook.
Deployment is handled via CI/CD on GitHub Actions or Vercel. We configure Sentry for error tracking, Plausible for analytics, and a staging environment for UAT. You own the entire codebase with no licenses or recurring fees.
- Source code in your GitHub repo
- CI/CD pipeline with GitHub Actions or Vercel
- TypeScript types for every component
- Storybook component library with documentation
- Unit tests with Vitest and E2E tests with Playwright
- Sentry error tracking and performance monitoring
- Lighthouse score report (target 90+)
- WCAG 2.1 AA accessibility audit report
- Deployment runbook and architecture diagram
- One month of post-release support
