IRPR is a team of senior frontend engineers who act as top frontend development consultants for B2B and B2C products. We specialize in React, Next.js, Vue, Angular, and TypeScript, and we build responsive, accessible, performant UIs that load under 2 seconds.

Why hire top frontend development consultants
A poorly built frontend costs you users, conversions, and developer time.
Most frontend projects fail because teams underestimate complexity. State management, responsive design, accessibility, and performance each require deep expertise. IRPR has shipped 200+ frontends across 50+ countries. We know how to avoid the common pitfalls that cause rewrites.
Our consultants bring senior-level experience from day one. You get a lead architect who designs the component tree, selects the right tools (React vs Vue vs Svelte), and sets up CI/CD pipelines. No junior developers, no learning curve. Your product ships on time.
Generic dev shop vs top frontend development consultants
Not all agencies deliver production-ready frontends that scale.
Many dev shops hand you a React app with no tests, no TypeScript, and no performance budget. You inherit technical debt that slows every future feature. IRPR treats frontend as a product, not a page.
We write typed code, enforce linting, and set up automated visual regression tests. Your team can extend the codebase without fear. We also document architecture decisions and provide a handover session.
- Uses outdated patterns (jQuery, messy CSS)
- No performance budget or Core Web Vitals tracking
- No TypeScript or type safety
- No component documentation
- No automated accessibility checks
- Hands over code without CI/CD
- React/Next.js with TypeScript from day one
- Performance budget enforced in CI (Lighthouse > 90)
- Full type coverage and strict mode
- Storybook with every component documented
- aXe and WAVE automated accessibility testing
- GitHub Actions CI/CD with preview deployments
How our frontend consulting engagement works
A structured process from discovery to deployment.
Every engagement starts with a 2-week Roadmap phase. We audit your current frontend (or spec a new one), define the tech stack, and produce a fixed-price quote. No surprises.
After you approve, we build in 2-week sprints. You see progress on a staging environment, review pull requests, and give feedback. We deploy to production when you say go.
What ships with every frontend engagement
You own everything. No black boxes.
When we finish, you get a production-ready frontend with all the tooling needed to maintain and scale it. No hidden licensing, no proprietary frameworks.
We also include a 30-day warranty period. If you find any bugs or need help with deployment, we respond within 24 hours.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Sentry error tracking setup
- Storybook component library
- Unit and integration tests (Jest + RTL)
- Lighthouse performance report (target > 90)
- Accessibility audit report (WCAG 2.1 AA)
- Deployment guide and runbook
- Post-launch 30-day support
