Senior Frontend Development ServicesDevelopment Services
We build fast, accessible frontends with React, Vue, or Angular. Your project ships in 8-12 weeks with a fixed price and full code ownership.
IRPR provides senior frontend development services for startups and enterprises. We use React 18, Next.js 14, Vue 3, Angular 16, and TypeScript 5 to build user interfaces that load under 2 seconds and pass WCAG 2.1 AA.
Every senior frontend development project ships in 8-12 weeks. Prices range from $80,000 to $250,000 depending on scope. We handle PCI-DSS for ecommerce frontends, HIPAA for healthcare portals, and SOC 2 for SaaS dashboards.
CTOs hire us when their in-house team lacks senior frontend architecture skills. Founders use us to build MVPs that investors want to see. Product managers bring us in to refactor legacy jQuery codebases into modern React or Vue apps.

Why senior frontend development services matter
A senior frontend developer writes code that loads fast, works on every device, and never breaks when the backend changes.
Junior developers produce code that passes review but ships with hidden tech debt. A senior frontend developer at IRPR writes TypeScript with strict mode, enforces ESLint rules, and sets up Playwright end-to-end tests before writing a single component. Every pull request is reviewed by another senior engineer. The result: zero regressions in production for over 90% of our projects.
We use React Query for data fetching, Zustand for state management, and Tailwind CSS for styling. Every project includes a CI/CD pipeline on GitHub Actions that runs linting, unit tests, and visual regression tests. We ship source maps, error tracking with Sentry, and performance budgets. Your team gets a frontend that is ready for the next 3 years of features.
Generic agency vs IRPR senior frontend development services
Not all frontend agencies deliver senior-level work. Here is what separates IRPR from a generic dev shop.
A generic agency assigns a mid-level developer who learned React from a weekend course. They copy code from Stack Overflow, skip tests, and deliver a frontend that crashes on Internet Explorer. When you ask for changes, they charge hourly and the timeline doubles.
IRPR assigns a senior frontend engineer with 8+ years of experience in React, Vue, or Angular. They write unit tests before components, use Playwright for end-to-end coverage, and set up Storybook for every reusable component. The project ships on time with a fixed price. You own the code from day one.
- Assigns mid-level developers with 2 years of experience
- No automated testing until bugs appear
- Charges hourly with no cap
- Delivers code with no type checking
- Uses outdated libraries like Bootstrap 4
- No performance budget or Lighthouse score target
- Assigns senior engineers with 8+ years of experience
- Writes unit tests and E2E tests before features ship
- Charges fixed price from week 2 Roadmap phase
- Enforces TypeScript strict mode on every project
- Uses Tailwind CSS, Shadcn, or custom design systems
- Targets Lighthouse score of 90+ on desktop and mobile
How our senior frontend development process works
We take your idea from a Figma mockup to a production-grade frontend in 8-12 weeks with zero guesswork.
Week 1 is the discovery call. We review your Figma files, API endpoints, and user flows. We estimate the scope and deliver a fixed price quote by the end of week 2. No surprises. No hidden fees.
Weeks 3-8 are the build phase. Our senior frontend developer sets up the React or Vue project with TypeScript, ESLint, and Playwright. They build components in Storybook, integrate with your backend via REST or GraphQL, and push code to your GitHub repo every day. You get a staging URL to test in real time. By week 10, the frontend is ready for production.
What ships with every senior frontend development project
Every senior frontend development engagement from IRPR includes these deliverables by default.
We do not deliver a zip file with code. You get a fully configured repository with CI/CD, monitoring, and documentation. Your team can start adding features the day after launch without calling us.
- Source code in your private GitHub or GitLab repo
- CI/CD pipeline with GitHub Actions (lint, test, build, deploy)
- Playwright end-to-end tests covering all critical user flows
- Storybook component library with visual regression tests
- Sentry error tracking with source maps
- Lighthouse performance report (target 90+)
- WCAG 2.1 AA accessibility audit and fixes
- TypeScript strict mode with ESLint rules
- Figma design token export for consistent theming
- Deployment guide and architecture documentation

You own the source code, design files, and all documentation from the first commit. We push code to your repository. No licensing fees, no lock-in, no recurring charges.
