Why hire UI frontend development consultants from IRPR
We bring senior-level expertise and a fixed-price model that eliminates risk.
IRPR has shipped 200+ frontends across 50 countries. Our consultants average 10+ years of experience with React, TypeScript, and Next.js. We use a four-phase process: Idea, Roadmap, Product, Release.
In the Roadmap phase (week 2), we deliver a fixed quote and a detailed technical specification. No hourly billing. No surprises. You know the cost and timeline before we write a single line of production code.
How IRPR is different from other frontend agencies
Most agencies bill hourly and change requirements mid-project. We do not.
When you hire generic frontend developers, you often get junior talent, unclear timelines, and scope creep. They use hourly billing, which rewards slow work. They hand off code without documentation or CI/CD.
IRPR assigns senior consultants only. We use fixed pricing from the Roadmap phase. Every project ships with a CI/CD pipeline, automated tests, and full documentation. We own the outcome, not the hours.
- Junior developers with 1-3 years experience
- Hourly billing with no cap
- No design system or component library
- Manual deployment with no CI/CD
- No performance auditing
- Code ownership often unclear
- Senior engineers with 10+ years experience
- Fixed price agreed in week 2
- Design system built on Storybook
- CI/CD pipeline on GitHub Actions
- Lighthouse scores 90+ on all pages
- Full code ownership, no licensing fees
Our 4-phase approach to UI frontend development consulting
We follow a repeatable process that reduces risk and speeds delivery.
Phase 1: Idea. We define the product vision, user personas, and core features in a 1-week discovery sprint. You get a product brief and a prioritized backlog.
Phase 2: Roadmap. We produce a technical specification, architecture diagram, and a fixed-price quote. This takes 1 week and costs $5K-$10K, credited toward the build.
