Senior Front End Development ServicesDevelopment Services
We build production-grade UIs with React, Next.js, Vue, and TypeScript. You get a senior-led team, fixed price, and delivery in 12 weeks.
IRPR provides senior front end development services to companies that need production-ready user interfaces built with modern frameworks like React, Next.js, Vue.js, and TypeScript. Our senior engineers write clean, testable code and ship fast without cutting corners.
A typical senior front end engagement runs 12 weeks from kickoff to launch. Pricing starts at $80K and goes to $250K depending on scope. Every project includes CI/CD, automated testing, and full code ownership. We comply with SOC 2 for SaaS, HIPAA for healthcare, and PCI-DSS for fintech clients.
Founders building a SaaS MVP hire us to get a polished front end in 3 months. CTOs at mid-market companies use us to modernize legacy UIs. Product teams at enterprises bring us in when they need senior React engineers for a critical feature. We also work with agencies that need overflow capacity on high-stakes front end work.

Why senior front end development services matter for your product
A poorly built front end costs you users and revenue. Our senior engineers ship UIs that are fast, accessible, and maintainable.
Hiring a junior or mid-level developer can lead to slow page loads, broken layouts, and code that no one wants to touch a year later. A senior front end engineer writes code with architecture in mind — they set up module bundling (webpack or Vite), linting (ESLint), formatting (Prettier), and testing (Jest, Cypress) from day one. This means your app loads in under 2 seconds and passes WCAG 2.1 AA accessibility standards.
IRPR only assigns engineers with 8+ years of experience. Our 200+ shipped products include both greenfield builds and rewrites of complex UIs. For example, one fintech client needed a real-time trading dashboard — we built it with React, Redux Toolkit, and WebSockets, achieving a 99.9% uptime on the front end and reducing latency by 40%.
How IRPR differs from generic front end agencies
Most agencies use hourly billing and junior developers. We give you a fixed price and a senior team that owns the outcome.
When you hire a generic development shop, you often get a project manager who filters requests, a junior developer who learns on your dime, and a handoff that leaves you with no documentation and a broken build. With IRPR, you talk directly to the lead engineer during the discovery call. We create a detailed roadmap in week 2 and lock the price. No surprises.
Our fixed-price model means we take the risk on scope. If we find a better way to implement a feature, we do it without charging more. And when the project ships, you get full source code in your own GitHub repository, a running CI/CD pipeline, and a written handoff guide. No black boxes.
- Hourly billing with no cap
- Junior developers assigned
- No dedicated testing
- Code delivered one time
- No CI/CD setup
- Handoff without documentation
- Fixed price from roadmap phase
- Senior engineers with 8+ years
- Automated tests in every sprint
- Source code in your repo
- CI/CD pipeline on GitHub Actions
- Full handoff guide + runbooks
Our senior front end development process: 4 phases
We use a proven framework: Idea, Roadmap, Product, Release. Every phase has clear milestones and client checkpoints.
The process starts with a 1-week Idea phase where we align on goals, user flows, and technical constraints. Then we build a detailed Roadmap in week 2 with wireframes, component architecture, and a fixed price. After approval, we launch the Product phase — 8 weeks of iterative development with biweekly demos. The Release phase covers testing, optimization, and deployment.
During the Product phase, our senior front end engineers work in sprints. Each sprint produces a deployable increment. We use GitHub Projects for tracking, Slack for daily communication, and a staging environment that you can use from week 4 onward.
