Why IRPR is the best scalable web app development agency
We have the track record to prove it.
IRPR has shipped over 200 web applications across 50 countries. Our average project delivers in 12 weeks with 98% on-time completion.
Every application we build is designed to scale horizontally. We use auto-scaling groups, CDNs, and database sharding from day one.
How we differ from other agencies
Most agencies talk about scaling. We build it.

Our process for building scalable web apps
We follow a proven 4-phase process that eliminates guesswork.
Every project starts with an Idea phase where we validate your concept and define the architecture. Then we move to Roadmap.
We build in 2-week sprints with continuous deployment. You see working software from week 3.
