Every engagement starts with a senior engineer assigned as team lead. We have shipped dashboards for a fintech unicorn, a custom design system for a Fortune 500 retailer, and a telemedicine interface used by 10,000 patients.
Our clients return because we deliver on time and on budget. 98% of IRPR projects ship within the original timeline. We back this with a fixed price from week 2 and a 3-month warranty.
Why not generic dev shops?
A senior front end development team from IRPR is different.
Generic dev shops assign junior developers and charge by the hour. Their code quality varies, and you never know the final cost. IRPR assigns a dedicated team of seniors with 10+ years of experience and gives you a fixed price upfront.
We also include design, performance tuning, and accessibility as standard. You get a design system in week 3, a Lighthouse score above 90, and WCAG 2.1 AA compliance. No hidden fees or scope creep.
- Junior developers, not seniors
- No design system included
- Slow iteration cycles
- Hidden costs and overages
- Code quality varies
- No post-launch support
- Senior engineers only (10+ years)
- Custom design system in week 3
- Agile sprints with weekly demos
- Fixed price from the Roadmap
- TypeScript, tested components, 90+ Lighthouse
- 3-month warranty on all code
How we build your front end in 12 weeks
From concept to production, our senior front end development team follows a proven process.
We start with a 1-week discovery sprint to understand your users and goals. Then we deliver a Roadmap with fixed price and timeline at week 2. After that, we build in 2-week sprints with weekly demos.
Every sprint includes design review, code review, and automated testing. You see working software every Friday. No black box; total transparency.
