Hire experienced frontend app development developersfrontend developers
We build production-grade frontends with React, Vue, or Angular. Fixed-price projects from $80K to $250K with a senior-only team.
IRPR is a team of senior frontend engineers who have built over 200 products across 50 countries. We use React 18, Vue 3, Angular 16, Next.js, and TypeScript to create responsive, accessible, and fast frontend apps for any industry.
Every project starts with a 2-week Roadmap phase where we define the architecture and UI component tree. Frontend MVPs ship in 8-12 weeks, and typical budgets range from $80,000 to $250,000. We handle all compliance requirements including WCAG 2.1 AA accessibility and GDPR data handling.
We work with founders who need a polished MVP for investor demos, CTOs who want to offload frontend complexity while scaling a SaaS product, and product directors who require a pixel-perfect UX redesign with measurable conversion improvement.

Why hire experienced frontend app development developers from IRPR
Our team averages 10+ years of frontend experience across dozens of frameworks and client verticals.
We ship frontend MVPs in 8-12 weeks with a fixed price determined during the Roadmap phase. Every project includes a full CI/CD pipeline on GitHub Actions, automated visual regression testing with Chromatic, and a deployment on Vercel or AWS.
All code is owned by you from day one. We write clean, well-documented TypeScript with unit tests (Jest, Vitest) and integration tests (Cypress, Playwright).
IRPR vs a typical frontend agency
Not all frontend teams are built the same. Here is how our developers compare.
A generic dev shop often assigns mid-level developers to your project after the sale. They change team members mid-project, which slows delivery and degrades code quality.
IRPR assigns a stable team of senior engineers who stay with you from Roadmap to release. We do not outsource parts of the frontend to offshore teams.
- Juniors or mid-level engineers on your project
- Unclear scope that leads to change orders
- Slow code reviews if any
- No frontend performance budget
- Generic UI library no custom design system
- No automated visual testing
- Senior engineers only, all 10+ years experience
- Fixed price after 2-week Roadmap phase
- Code reviews every push via GitHub Actions
- 80+ Lighthouse score target from day one
- Custom component library in Storybook
- Automated regression checks with Chromatic
How we build your frontend app step by step
Our frontend development process ensures quality, speed, and transparency at every stage.
Phase 1 is a 2-week Roadmap where we wireframe every screen, define the component tree, and estimate every feature. You get a fixed price and a timeline before any code is written.
Then we move into 2-week sprints. Every sprint ends with a deployable build on a staging environment. You review the frontend live, not on Figma mockups alone.
What ships with every frontend engagement
Every project includes a standard set of deliverables that guarantee quality and maintainability.
You receive the complete source code in your own GitHub repository from the start. We set up all infrastructure code for CI/CD, monitoring, and error tracking.
Documentation is written as we code: a README, a component README in Storybook, and an API contract document kept in sync with the backend.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions with lint and test stages
- Sentry error tracking and performance monitoring
- Storybook component library with all states
- Cypress and Playwright end-to-end tests
- Lighthouse performance report with 80+ scores
- 100% pixel-perfect Figma to code matching
- Responsive layout tested on iPhone, iPad, Android, desktop
What we ship in this practice.
SaaS analytics dashboard
We built a real-time analytics dashboard for a SaaS company using React 18, D3.js, and WebSockets. The UI displays 5,000+ data points per view with sub-200ms render time. Reduced page load from 3.2s to 0.8s. Industry: SaaS

Why teams hire us.
Senior engineers only
Every frontend developer at IRPR has at least 10 years of production experience. We do not staff juniors or outsource work. Your team stays consistent from kickoff to deployment.
Fixed price after a 2-week Roadmap
We spend the first 2 weeks defining every feature, component, and screen. Then we give you a fixed price. No hourly billing, no surprise overruns.
Full code ownership from day one
Your code lives in your GitHub repository from the very first commit. You own the IP, the source code, and the design system. No licensing strings.
98% on-time delivery track record
We have delivered 200+ products and 98% of them on or before the original deadline. We plan sprints with buffer for real-world delays.
