Senior frontend app development team by the numbers
Our team ships frontends that perform at scale.
IRPR has delivered over 200 frontend applications to clients in 50+ countries. Our average project completes in 12 weeks.
With a 98% on-time delivery rate and fixed pricing, you can budget confidently for your senior frontend app development team.
Generic dev shop vs IRPR senior frontend team
Most agencies assign junior devs. We don't.
Generic shops often hand your project to a junior developer learning on the job. IRPR assigns only senior engineers with 5+ years of production experience.
Our team uses automated testing, performance budgets, and component libraries from day one. This means faster delivery and higher quality.
- assigns junior developers
- code lacks unit tests
- slow iteration cycles
- poor Core Web Vitals scores
- no reusable design system
- vague hourly pricing
- senior engineers only
- automated testing pipeline (Jest, Cypress)
- 2-week sprint cycles
- targets Lighthouse scores above 90
- Storybook component library
- fixed price after Roadmap phase
