Premium Frontend Web Development ConsultantsFrontend Consultants
We build production-grade UI layers that load fast, scale clean, and ship in 12 weeks. 200+ products shipped across 50 countries with a 98% on-time rate.
IRPR's senior frontend engineers build user interfaces that convert, load under 2 seconds, and pass WCAG AA accessibility. We specialize in React 18, Vue 3, Angular 16, and Next.js 14 with TypeScript, GraphQL, and Tailwind CSS.
Every engagement ships source code to your repo, a CI/CD pipeline on GitHub Actions, Sentry error tracking, and Lighthouse scores above 90. Timeline is 8-12 weeks from kickoff to deployment. Fixed pricing starts at $80K for a single-page app and goes up to $250K for a multi-module enterprise frontend. We comply with SOC 2 and HIPAA where needed.
Our clients are CTOs at Series A-B startups who need a scalable design system, VPs of Engineering at Fintechs who require sub-100ms interaction times, and Product Owners at SaaS companies who want a pixel-perfect UI that their own team can extend after handoff.

Why hire premium frontend web development consultants
IRPR's frontend consultants bring deep expertise in React, Vue, Angular, and the modern JavaScript ecosystem.
Generic dev shops treat the frontend as a thin layer. We treat it as the product. Our engineers write code that passes strict lint rules, hits 90+ Lighthouse scores, and runs at 60fps. We test with Jest, Cypress, and Playwright to catch regressions before they reach users.
We also handle deployment. Every project ships with a CI/CD pipeline on GitHub Actions, automated preview deployments on Vercel, and performance monitoring with Sentry. You get a fully operational frontend that your team can take over in week 12.
Premium frontend vs. generic development shops
Not every agency can deliver a production-grade UI that performs under load.
Generic shops often use pre-built templates that don't scale. They skip state management, ignore accessibility, and ship unoptimized bundles. You end up with a slow site that fails audits and frustrates users.
IRPR builds from scratch with your specific use case in mind. We design component trees, manage state with Redux or Zustand, and optimize bundle size with code splitting. The result is a frontend that loads fast and is easy to maintain.
- Uses WordPress or template builders
- No automated testing or CI/CD
- Load times over 3 seconds
- No accessibility compliance
- No performance budget
- Source code not cleanly structured
- Custom React/Vue/Angular code with TypeScript
- Cypress + Playwright test suite in every project
- Lighthouse 90+ on mobile and desktop
- WCAG AA compliance tested with axe-core
- Bundle size budget enforced in CI
- Full source code ownership with modular architecture
Our frontend development process
IRPR follows a 4-phase process that starts with a fixed-price Roadmap and ends with a production deployment.
Phase 1 is a 1-week kickoff call where we map your current state and define the target UI. Phase 2 is a 2-week Roadmap where we wireframe key screens, choose the stack, and give you a fixed price. Phase 3 is the 8-10 week build cycle with bi-weekly demos. Phase 4 is a 2-week release and handoff.
Your team gets full access to our GitHub repo, Notion docs, and a shared Slack channel. By week 10, you have a production-ready frontend that passes your QA and is ready to deploy.
Ships with every frontend project
Every project includes these deliverables by default. No hidden fees or optional extras.
We believe in transparency. What we quote is what you get. All code, configurations, and documentation are yours to keep.

Why teams hire us.
Senior engineers only, no juniors
Every IRPR engineer has 8+ years of frontend experience. We never staff juniors or trainees. Your project is built by a lead who has shipped at least 10 production apps.
Fixed price from the Roadmap
We give you a fixed price in week 2 after a thorough Roadmap phase. No hourly billing. No surprise invoices. The price you approve is the price you pay.
12-week timeline with bi-weekly demos
Your first demo happens in week 2. Every 2 weeks you see progress. By week 12 you have a production-ready frontend that you can deploy immediately.
Full code ownership
When the project ends, you own every line of code, every config file, and every test. No licensing fees. No locked-in contracts. Your repo, your IP.
Compliance-ready for HIPAA and SOC 2
We build with compliance in mind. Our frontends support HIPAA audit logging, SOC 2 access controls, and PCI-DSS tokenization for payment fields.
Performance is not optional
Every project ships with a Lighthouse budget enforced in CI. If a PR drops the score below 90, the build fails. Your users get fast, reliable interfaces.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
