Best Frontend Development Consultants Deliver Measurable Results
IRPRs frontend consultants have shipped 200+ products across 50+ countries with consistent on-time delivery.
Every engagement starts with a detailed Roadmap phase where we define scope, architecture, and a fixed price. No hourly billing, no surprises. Our senior engineers have an average of 10+ years of experience and work directly on your codebase.
We measure success by real metrics: page load times under 2 seconds, Lighthouse scores above 90, and zero production regressions across deployments. Clients report 30-50% faster time-to-market compared to building in-house.
Generic Frontend Agencies vs IRPR Consultants
Most agencies bill hourly and deliver slow, buggy code. IRPR gives you a fixed price, clear scope, and a senior team that ships fast.
Typical frontend shops employ junior developers, avoid upfront architecture, and let scope creep inflate timelines. You end up with a fragile codebase and monthly invoices that never end.
IRPR frontend consultants start with a two-week Roadmap to lock scope and price. You get weekly demos, a dedicated project manager, and full code ownership. No surprises, no ghosting.
- Billing by the hour
- No fixed scope
- Junior developers on the team
- Unclear communication via email only
- Last-minute changes that blow budget
- Late delivery or no delivery guarantee
- Fixed price from day one
- Explicit roadmap in week 2
- Senior engineers only (10+ years avg)
- Weekly video standups and Slack access
- Change requests scoped before implementation
- 8-12 week delivery with 98% on-time record
Our Process for Frontend Consulting Engagements
IRPR follows a structured four-phase process that guarantees clarity, speed, and quality.
Phase one is Discovery: we interview your stakeholders, review existing code, and define the problem. Phase two is Architecture: we pick the right stack (React vs Vue vs Svelte), set up the repo, and design the component tree.
Phase three is Development: we build features in parallel with automated testing and daily deployments. Phase four is Handoff: we ship the code to your repo, provide a runbook, and train your team.
What Ships With Every Frontend Engagement
Every project includes all the assets and documentation your team needs to maintain and scale the product.
You get the full source code in your private GitHub repo from day one. We include CI/CD pipelines, automated tests, and a performance budget. No dependencies on us to deploy or fix bugs.
Documentation includes Storybook for every component, a style guide, and an API integration layer. We also provide a deployment runbook and a 30-day support period.
- Source code in your private GitHub repo
- CI/CD pipeline on Vercel / Netlify / GitHub Actions
- Unit tests with Jest and integration tests with Cypress
- Storybook component documentation with all states
- Performance budget report (Lighthouse 90+ targets)
- Accessibility audit for WCAG 2.1 AA compliance
- Design token file (CSS variables or Tailwind config)
- API integration layer with error handling and caching
- Responsive breakpoints documented with screenshots
- Deployment runbook and 30-day support hand-off
