Top UI Frontend Development DevelopersDevelopers
We build pixel-perfect, fast frontends for serious products. 200+ shipped, 12-week MVPs, fixed price.
IRPR connects you with top UI frontend development developers who build in React, Vue.js, Angular, and TypeScript. We ship production-grade frontends with state management (Redux, Pinia), design systems (Storybook), and performance optimization (Lighthouse scores 90+).
Every frontend project ships in 8-12 weeks. Pricing is fixed: $80K-$250K depending on scope. We handle compliance for HIPAA, PCI-DSS, and SOC 2 environments. Code is fully owned by you - no licensing, no lock-in.
Founders with a UI-heavy concept hire us to turn Figma into fast, accessible web apps. CTOs outsource frontend build to reduce hiring risk. Product managers commission modular component libraries that scale without tech debt.

Why top UI frontend development developers at IRPR ship faster
Our developers use battle-tested workflows and tooling that eliminate guesswork.
IRPR developers work in React 18, Next.js 14, and Vue 3 with TypeScript by default. Every project starts with a design system built in Figma and Storybook to keep UI consistent across 20+ components. We use Tailwind CSS for utility-first styling and reduce production CSS size by 40% compared to hand-rolled CSS.
Testing is automated: Playwright for end-to-end, Vitest for unit, and Lighthouse CI for performance budgets. We deploy on Vercel or AWS via GitHub Actions with automatic branch previews. The result is a frontend that loads under 2 seconds on 3G and passes WCAG 2.1 AA.
How IRPR's top UI frontend development developers differ from freelancers
A single senior developer is great. A team that coordinates design, code, testing, and deployment is better.
Hiring freelancers for frontend work often leads to inconsistent code, broken design handoffs, and no long-term accountability. IRPR assigns a team of 2-3 senior developers (7+ years each) plus a project manager and QA engineer. We work in 2-week sprints with daily standups and a shared Jira board.
Every artifact is documented: component API in Storybook, state management decisions in ADRs, and deployment scripts in infrastructure-as-code. We guarantee the frontend passes your Lighthouse score target (we set 90+ for mobile). If code quality drops, we refactor before it becomes debt.
- No design system handoff
- Mixed code quality, no reviews
- No automated testing (or minimal)
- Limited availability post-launch
- Hourly billing with scope creep
- No ownership of deployment pipeline
- Design system in Storybook + Figma tokens
- Code review required on every pull request
- Full Playwright + Vitest test suite
- 12-month warranty on code defects
- Fixed price with no surprise charges
- CI/CD with Vercel or AWS, fully automated
The frontend development process IRPR follows
From concept to production, we follow four disciplined phases.
Our process starts with a 2-week Roadmap phase where we translate your Figma or sketches into a component tree, define data flow with React Query or Pinia, and set up the tech stack. No coding happens until you approve the architecture.
Production sprints run in 2-week cycles with a deployable build at the end of each sprint. We demo the working frontend on a staging URL after every sprint. Final release includes performance optimization, accessibility audit, and deployment runbook.
What ships with every frontend project at IRPR
You walk away with more than just code. Every frontend includes these deliverables.
We ship a production-ready single-page application or server-rendered app depending on your needs. All code is written in TypeScript and follows the same linting and formatting standard (ESLint + Prettier).
The delivery includes a live style guide (Storybook), automated test reports, and a deployment playbook. You own every file. No proprietary frameworks, no open-source license risk.
- Full source code in your private GitHub repo
- CI/CD pipeline (GitHub Actions + Vercel/AWS)
- Storybook with every component documented
- Playwright end-to-end tests (20+ scenarios)
- Lighthouse performance report (target 90+ mobile)
- WCAG 2.1 AA compliance report
- Component API documentation in markdown
- Deployment runbook (one-pager)
- Figma component link (if design system started in Figma)
- Sentry error tracking integration

Why teams hire us.
Fixed price, not hourly billing
We quote a fixed price during the Roadmap phase. No hourly surprises. The price covers design, development, testing, and deployment. Change requests are scoped and priced upfront.
Senior developers only, no juniors
Every developer at IRPR has 7+ years of frontend experience. We don't outsource to junior teams. The team you meet in the discovery call writes the code that ships.
Full code ownership from day one
You own the entire codebase, design tokens, and documentation. IRPR licenses nothing. No proprietary frameworks. No vendor lock-in. You can take the code to any team.
Design system included in every build
We create a reusable component library in Storybook with Figma tokens. New screens reuse existing components. Design debt doesn't accumulate because the system scales.
Performance is not an afterthought
We set a Lighthouse target of 90+ mobile and 95+ desktop. Every merge triggers a performance regression check. We optimize images, fonts, and bundles before release.
12-month warranty on code defects
If a bug is found within 12 months of release, we fix it at no extra charge. Our average fix turnaround is 48 hours. This covers browsers, APIs, and security patches.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
