Senior UI Frontend Development ServicesDevelopment Services
We build production-grade frontends with React, TypeScript, and Next.js. You get a pixel-perfect UI that ships in 8-12 weeks.
IRPR provides senior ui frontend development services for companies that need production-quality interfaces built with React, TypeScript, Next.js, and Tailwind CSS. We skip the juniors and assign only senior engineers with 7+ years of experience.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle accessibility (WCAG 2.1 AA), performance optimization (Lighthouse 90+), and cross-browser compatibility. You own the full source code from day one.
Our clients are CTOs at funded startups who need a v1 frontend in 10 weeks, product managers at mid-market companies modernizing a legacy UI, and agency owners who outsource frontend builds to a reliable team with enterprise compliance (SOC 2, HIPAA, PCI-DSS).

What senior ui frontend development services include
Every engagement delivers a production-ready frontend with a clear architecture and measurable outcomes.
Our senior engineers write code that scales. We use Next.js for server-rendered pages, React for interactive components, and TypeScript to catch bugs before they reach production. Every project includes a Storybook component library, automated tests (Jest, Cypress), and a CI/CD pipeline on GitHub Actions.
We measure success by real metrics: Lighthouse scores above 90, bundle sizes under 200KB for initial load, and zero regression bugs in production. For one fintech client, we reduced their frontend load time from 4.2 seconds to 1.1 seconds, increasing conversion by 22%.
How IRPR differs from generic frontend shops
Most agencies assign junior devs, use hourly billing, and deliver code that doesn't scale. We do the opposite.
Generic shops often hand your project to a junior developer who learns on the job. You pay hourly for their learning curve. The code lacks tests, accessibility, and performance budgets. You get a UI that works on one browser and falls apart on mobile.
IRPR assigns senior engineers only — each with 7+ years of experience. We quote a fixed price after a 2-week Roadmap phase. Every deliverable includes a component library, automated tests, and a CI/CD pipeline. You own the code, the design system, and the deployment.

Our senior ui frontend development process
We follow a structured 4-phase process that turns your idea into a production-ready UI.
Phase 1: Idea. We align on goals, user flows, and technical constraints in a 1-week sprint. You get a written scope document with wireframes and a tech stack recommendation.
Phase 2: Roadmap. In week 2, we define the architecture, component tree, and data flow. You get a fixed price quote and a timeline with milestones.
What ships with every senior ui frontend project
Every engagement includes these deliverables by default — no hidden extras.
We ship more than just code. Every project includes a living design system, automated tests, and a deployment pipeline. You can hand the code to any internal team or maintain it yourself.
- Source code in your private GitHub repo
- Storybook component library with all UI components
- CI/CD pipeline on GitHub Actions
- Automated tests: unit (Jest), integration (React Testing Library), e2e (Cypress)
