Why hire a senior frontend app development firm
Senior frontend engineers build faster, write cleaner code, and ship fewer bugs.
A junior or mid-level developer might take 16-20 weeks to build a production-ready React app. Our senior engineers ship the same app in 8-12 weeks because they know patterns like compound components, render props, and custom hooks. They set up error boundaries, performance monitoring with Lighthouse, and automated testing with Cypress from day one.
IRPR's senior frontend team has shipped 200+ products across 50+ countries. Every engineer has worked on apps handling 1M+ monthly active users. We use a fixed-price model so you know the cost upfront. No hourly billing, no scope creep, no surprises.
How IRPR differs from other frontend agencies
Most agencies assign juniors to your project. We assign senior engineers only.
A typical dev agency hires junior developers at $30/hour and puts them on client projects. They learn on your dime. IRPR does the opposite. Every engineer on your project has 8+ years of experience and has shipped at least 5 production apps. We skip the learning curve.
We also fix the price before we write a single line of code. Our Roadmap phase (week 2) produces a detailed scope, architecture diagram, and fixed quote. You approve the price before we build. No hourly billing, no daily rate, no time tracking.

Our frontend development process
We break every project into four phases. Each phase has a clear deliverable.
Phase 1 is the Idea phase. We review your product concept, user flows, and design mockups in Figma. Phase 2 is the Roadmap phase where we produce a technical architecture document, component tree, and fixed price quote.
Phase 3 is the Product phase where we build the frontend in weekly sprints. Phase 4 is the Release phase where we deploy to production, set up monitoring with Sentry, and hand over the source code.
What ships with every frontend project
Every project includes these deliverables by default. No hidden costs.
When you hire IRPR as your senior frontend app development firm, you get more than just code. You get a production-ready frontend with monitoring, testing, and documentation. Everything is yours. You own the full IP and source code.
We also provide a handover guide so your internal team can take over maintenance. If you don't have an internal team, we offer ongoing support at a fixed monthly retainer.
