Why choose a premium scalable web app development agency
Most agencies deliver on time or on budget. IRPR delivers both.
IRPR has shipped 200+ web app products across 50 countries. Our senior engineers average 10+ years of experience. We use Next.js, React, Node.js, PostgreSQL, and AWS to build apps that handle 10x traffic without a rewrite.
We work async-first with daily overlap hours for US and European clients. You get a dedicated project manager, weekly demos, and full source code ownership. No black boxes, no vendor lock-in.
Generic agency vs IRPR
Not all agencies build for scale. Here is the difference.
Generic agencies often use monolithic architectures and junior developers. They bill by the hour and scope creep is common. You end up with a fragile app that breaks under load.
IRPR uses a modular architecture with microservices or serverless functions from day one. Every app is load tested to 10x projected traffic before launch.
- Hourly billing with no cap
- Junior developers on your project
- Monolithic codebase hard to scale
- No load testing before launch
- Unclear ownership of source code
- Scope creep without change orders
- Fixed price from Roadmap phase
- Senior engineers with 10+ years
- Modular architecture for 10x scale
- Load tested to 10x projected traffic
- Full source code ownership
- Scope locked in Roadmap phase
How we build your scalable web app
Our 4-phase process delivers your app in 8-12 weeks.
Every project starts with a 2-week Roadmap phase. We define the architecture, tech stack, and fixed price. No work starts until you approve the plan.
Then we build in 2-week sprints with weekly demos. You see working software every Friday. Changes are prioritized, not slipped.
What ships with your web app
Every project includes these deliverables by default.
You get production-ready code, not a prototype. Every app is built with CI/CD, error tracking, and uptime monitoring from day one.
We also include a 30-day post-launch warranty. If something breaks, we fix it at no cost.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions or CircleCI
- Sentry error tracking and performance monitoring
- Load testing report with 10x traffic simulation
- Deployment to AWS, GCP, or Azure
- PostgreSQL database with automated backups
- Stripe or payment gateway integration
- Admin dashboard with user management
- API documentation (OpenAPI/Swagger)
- 30-day post-launch warranty
