Senior UI Frontend Development CompanyFrontend Development
Senior UI engineers build your product in 8-12 weeks. Fixed price, no hourly billing, full code ownership.
IRPR is a senior UI frontend development company. We build interfaces with React, Vue.js, Next.js, and TypeScript. Every engineer has 10+ years of experience and ships production code from week one.
We deliver a working MVP in 8-12 weeks. Pricing is fixed from the Roadmap phase, ranging from $80K to $250K depending on complexity. All projects include CI/CD, error monitoring with Sentry, and full source code ownership.
Founders hire us when they need a polished product but cannot find senior frontend talent. CTOs bring us in to rebuild legacy UIs without hiring a full team. Product managers work with us to ship complex dashboards and data-heavy interfaces on schedule.

Why a senior UI frontend development company matters
Junior developers cost less but cost you more in rework, slow performance, and missed deadlines.
IRPR only hires senior engineers with 10+ years of experience. Every developer has shipped at least 5 production products before joining. We do not outsource to junior talent or offshore shops that rotate staff mid-project.
Our team averages 12 years of frontend experience. We use TypeScript, React, Vue, and Next.js daily. We also handle state management (Redux, Zustand, Pinia), testing (Cypress, Playwright), and performance optimization (Lighthouse scores above 90).
The difference between generic dev shops and IRPR
Most agencies send you a junior developer who learns on your dime. IRPR sends a senior engineer who ships from day one.
Generic dev shops often assign one senior to sell the project and a junior to build it. They churn through developers, change scope without notice, and deliver bloated code that breaks in production.
IRPR assigns a dedicated senior engineer from the discovery call. That same person writes the code, reviews the PRs, and deploys to production. You get one point of contact, one consistent code style, and zero handoff overhead.
- Assigns junior developers after the sale
- Charges hourly with no cap
- Uses outdated libraries or reinvents wheels
- Delivers code without tests or CI/CD
- Switches team members mid-project
- Owns the code until final payment
- Assigns a senior engineer from day one
- Fixed price from the Roadmap phase
- Uses modern stacks: React, Next.js, TypeScript
- Ships with Cypress tests and GitHub Actions CI/CD
- Same team for the full project
- You own the code immediately
How IRPR builds your UI frontend in 4 phases
Every project follows a structured 4-phase process designed to reduce risk and deliver fast.
Phase 1 (Idea) is a 1-week discovery where we map your user flows, data models, and visual requirements. We deliver a written spec and wireframes. No code is written yet.
Phase 2 (Roadmap) is week 2. We break the spec into 2-week sprints, estimate each one, and set a fixed price. You approve the plan and we start building.
What ships with every UI frontend project
Every project includes a complete production-ready frontend, not just code.
We deliver a fully functional UI that runs in staging within the first 2 weeks. By week 6, you have a beta that real users can test. By week 12, the app is in production with monitoring and alerts.
All code is written in TypeScript with a consistent style via ESLint and Prettier. We include a Storybook component library, end-to-end tests with Playwright, and a deployment pipeline on Vercel or AWS.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions and Vercel
- Sentry error tracking and performance monitoring
- Storybook component library with all UI components
- End-to-end tests with Playwright (90%+ coverage)
- Lighthouse performance report (score 90+)
- Design system documentation in Notion or Markdown
- Deployment to staging environment by week 2
- Admin documentation for future developers
