Results from our senior frontend web development agency
We measure success by ship speed, performance, and maintainability.
Our senior engineers have shipped over 200 frontend products across 50+ countries. Each project follows a structured 8-12 week timeline with fixed pricing, so you know exactly what you get and when.
Performance benchmarks include sub-2-second load times, Lighthouse scores above 90, and accessibility compliance with WCAG 2.1 AA. We set up Sentry error tracking and CI/CD on day one.
Why not all senior frontend web development agencies are equal
Most agencies bill hourly and hand off messy code. We do the opposite.
Generic dev shops often assign junior developers to your project, bill by the hour, and deliver bloated code with no tests. You pay more and wait longer for results that don't scale.
IRPR assigns only senior engineers with 10+ years of experience. We quote a fixed price after a 2-week Roadmap phase, so you never face surprise invoices. Every line of code is peer-reviewed and ships with full test coverage.
- Junior or mid-level developers on your project
- Hourly billing with unpredictable costs
- No dedicated product manager
- Code delivered without documentation
- No CI/CD or error monitoring setup
- Slow communication across time zones
- All senior engineers with 10+ years experience
- Fixed price per project after Roadmap phase
- Dedicated technical lead and PM
- Full Storybook library and automated tests
- CI/CD on GitHub Actions, Sentry monitoring
- Async-first with daily overlap hours for your timezone
Our process for senior frontend web development agency projects
We follow a repeatable framework that minimizes risk and maximizes speed.
Every engagement starts with a 2-week Roadmap phase where we define architecture, user flows, and a fixed-price quote. This avoids scope creep and aligns expectations before a single line of code is written.
From there we move into 4-week Product sprints, each delivering a shippable increment. By week 8 you have a production-ready frontend, and by week 12 we hand over full code ownership with training.
What ships with every senior frontend web development agency project
No black boxes. Every deliverable is a working piece of your product.
We don't just hand over a zip file. Every project ships with a production-ready codebase, full CI/CD pipeline, and monitoring. You can take the code to any other team and they can run it immediately.
Our checklist ensures you get everything needed for long-term maintainability and scaling.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions with automated tests
- Sentry error tracking and performance monitoring
- Storybook component library with all states documented
- Lighthouse score above 90 for performance and accessibility
- Full test coverage (unit + integration + e2e with Cypress or Playwright)
- Responsive design across mobile, tablet, and desktop
- Environment variables, secrets, and deployment scripts
- README with architecture overview and local dev setup
- 2-hour handover session with your engineering team
