Why top front end development consultants choose IRPR
We have shipped 200+ front ends that load fast, scale linearly, and pass accessibility audits.
Every project starts with a 2-week Roadmap phase where we define the component tree, data flow, and delivery milestones. You get a fixed price, not a time estimate. We use React 18, Next.js 14, and TypeScript 5 by default because those tools give the best developer experience and runtime performance.
Our consultants are senior engineers who have worked at Google, Microsoft, and Stripe. They write tests (Jest, Playwright), configure CI/CD (GitHub Actions, Vercel), and document every API contract. We own the front end architecture so you can focus on your product market fit.
Generic dev shops vs IRPR front end consultants
Most agencies overpromise speed and underdeliver on code quality. Here is the difference.
A generic dev shop will hand off a React app with no tests, no CI, and a bundle size over 2 MB. They use the cheapest junior talent and bill by the hour. You get a mess that breaks on the next npm update.
IRPR writes every component with TypeScript, ships 80%+ test coverage, and deploys on Vercel with automatic branch previews. Our consultants are U.S.-based senior engineers who charge a fixed price for the whole scope. You get a production-ready front end that your team can maintain.
- Junior developers with 1-2 years experience
- Hourly billing that encourages slow work
- No automated testing or CI/CD
- Bundle size over 1.5 MB
- No accessibility audit (WCAG)
- Code not documented or componentized
- Senior engineers with 10+ years each
- Fixed price per project (no surprises)
- Jest + Playwright tests in every sprint
- Bundle under 200 KB with code splitting
- WCAG AA compliance built in
- Full Storybook design system shipped
How our top front end development consultants work
We follow a four-phase process that turns your idea into a deployable product.
Every engagement begins with a 1-week discovery where we audit your existing codebase or wireframes. You get a detailed technical roadmap with a fixed price. No guesswork.
We then build the front end in 6-10 weeks, delivering a working app on Vercel or your own infrastructure. You can see progress every Monday via a live preview link.
What ships with every front end engagement
Every project includes a complete delivery package, not just code.
You own everything we build. No locked-in IP, no recurring license. We hand over the source code, CI/CD pipelines, and deployment configuration on day one.
Our documentation includes a README with setup instructions, a component storybook, and a runbook for deploying updates. Your team can take over without us.
- Source code in your private GitHub repository
- CI/CD with GitHub Actions and Vercel
- Storybook component library with all states
- Jest unit tests with 80%+ coverage
- Playwright end-to-end tests for critical flows
- TypeScript strict mode with no `any`
- WCAG AA accessibility report
- Lighthouse score report (90+ performance)
- Deployment runbook and environment variables
- Figma or Sketch design file (if provided)
