Expert Frontend App Development PartnerDevelopment Partner
Senior engineers build your frontend in 12 weeks. Fixed price, no surprises.
IRPR is an expert frontend app development partner that builds production-grade frontends with React, Vue.js, Angular, and Next.js. Our senior engineers write clean, type-safe code with TypeScript, automated tests with Cypress, and optimized bundles with Webpack or Vite.
We ship a complete, tested frontend in 12 to 16 weeks depending on complexity. Pricing is fixed at $80K to $250K per project. Every deliverable passes WCAG 2.1 AA accessibility checks and supports all modern browsers down to IE11 if required.
Founders hire us to launch a customer-facing MVP that converts. CTOs hire us to rebuild a legacy frontend that is slow and unmaintainable. Product managers hire us to build a scalable design system that their internal team can extend. Each engagement includes a dedicated project lead who reports weekly.

Why you need an expert frontend app development partner
A generic frontend agency delivers generic results. An expert partner delivers a product that converts, loads fast, and scales.
Most frontend projects fail because the agency lacks senior engineers. Junior devs write code that works on one screen but breaks on another. They skip accessibility, ignore performance budgets, and produce a codebase your team cannot maintain. IRPR assigns only senior engineers with 10+ years of experience. Every line of code is reviewed by a second senior engineer before it ships.
We follow a strict process: design review, component architecture, state management plan, API contract, automated tests, and performance audits at each milestone. The result is a frontend that scores 90+ on Lighthouse, passes WCAG 2.1 AA, and loads in under 2 seconds on a 3G connection. Our clients see conversion rates increase by 20% on average.
Generic agency vs. expert frontend development partner
Not all frontend teams are equal. Here is what you avoid when you hire IRPR.
A generic dev shop might promise a React app in 8 weeks. They deliver in 14 weeks with no tests, no documentation, and a bundle that takes 5 seconds to load. You then spend another 6 weeks fixing their mistakes. IRPR delivers on time with a complete test suite and a performance budget of under 200KB initial JavaScript.
We also provide a handover package that includes a component library in Storybook, a CI/CD pipeline on GitHub Actions, and a deployment guide for AWS or Vercel. Your internal team can take over immediately without a ramp-up period.
- Junior developers with 1-2 years of React
- No automated tests shipped
- No performance budget enforced
- No accessibility audit
- No design system or component library
- No handover documentation
- Senior engineers with 10+ years experience
- Cypress and Jest test suite included
- Lighthouse score 90+ guaranteed
- WCAG 2.1 AA compliance passed
- Storybook component library delivered
- Full CI/CD pipeline with GitHub Actions
Our frontend development process
We follow a four-phase process that de-risks your investment and delivers a production-ready frontend on time.
Phase 1 is the Idea phase where we review your Figma designs and API contracts. We identify state management needs, routing structure, and performance targets. This phase takes 1 week and ends with a technical specification document.
Phase 2 is the Roadmap phase where we break the work into 2-week sprints. Each sprint has a clear deliverable: a working component, a page, or an integration. You see progress every two weeks. Phase 3 is the Product phase where we build, test, and deploy. Phase 4 is the Release phase where we monitor performance and fix any issues within 30 days.
What ships with every frontend project
Every engagement includes a standard set of deliverables that makes your team self-sufficient after launch.
You get more than just a working frontend. You get a complete developer kit that your internal team can use to extend and maintain the product. We document every decision and every component so there is no knowledge gap.
All code is stored in your private GitHub repository. You own the IP from day one. We also include a deployment guide that covers both staging and production environments on AWS, Vercel, or Netlify.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions with automated tests
- Storybook component library with all UI components
- Cypress end-to-end test suite covering all user flows
- Lighthouse performance report with score 90+
- WCAG 2.1 AA accessibility audit report
- Deployment guide for staging and production environments
- Sentry error tracking configured
- Figma design token export for design consistency

Why teams hire us.
Fixed price from day one
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. The price you see is the price you pay.
Senior engineers only
We do not hire juniors. Every engineer on your project has 10+ years of experience and has shipped at least 5 production frontends. You get a lead engineer who stays on your project from start to finish.
12-week MVP delivery
Most frontend MVPs ship in 12 weeks. We have a repeatable process that eliminates wasted time. Your first sprint ends with a deployable component, not just a wireframe.
Full ownership of code
You own all source code, design files, and documentation from day one. No licensing fees, no recurring royalties. We transfer everything to your GitHub account at the end of the project.
Accessibility and performance built in
Every frontend we build passes WCAG 2.1 AA and scores 90+ on Lighthouse. We do not treat accessibility as an afterthought. It is part of every sprint definition of done.
30-day post-launch support
After we deploy to production, we monitor for 30 days and fix any issues that arise. We also provide a 1-hour handover call with your team to answer any questions about the codebase.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
