Leading Scalable Web App Development FirmScalable Web App
We build web apps that handle millions of users. Fixed price, 8-12 week MVPs, senior engineers only.
IRPR is a leading scalable web app development firm. We build web applications with React, Next.js, Node.js, Python, and Go on AWS or GCP. Every app uses horizontal scaling, caching layers (Redis), and CDN distribution (CloudFront) to handle traffic spikes.
We ship production-ready web apps in 8-12 weeks. Pricing is fixed: $80K-$250K per project. We support compliance standards like HIPAA, PCI-DSS, and SOC 2. You own the source code from day one.
Founders hire us to build a scalable MVP that can grow to 100K users. CTOs hire us to rebuild legacy monoliths into microservices. Product managers hire us to add real-time features like chat or live dashboards. Agencies hire us to white-label development for their clients.

Why choose a leading scalable web app development firm
Scalability is not an afterthought. It is built into the architecture from day one.
A scalable web app handles 100 users and 1 million users on the same codebase. IRPR designs every app with horizontal scaling in mind. We use auto-scaling groups on AWS, database read replicas, and CDN caching to keep response times under 200ms.
We also build in monitoring from the start. Every app ships with Sentry error tracking, Datadog performance monitoring, and CloudWatch alerts. You get a dashboard that shows real-time traffic, error rates, and server load.
Generic dev shop vs leading scalable web app development firm
Not all web development firms build for scale. Here is the difference.
Many development shops focus on getting the app out the door. They use a single server, a monolithic codebase, and no caching. When traffic grows, the app slows down or crashes.
IRPR builds for scale from the start. We use microservices, database sharding, and CDN caching. Your app can handle 10x traffic without a rewrite.
- Monolithic architecture
- Single database instance
- No load testing
- No auto-scaling
- No CDN
- No monitoring
- Microservices or modular monolith
- Read replicas + caching layer
- Load testing with k6
- Auto-scaling on AWS/GCP
- CloudFront CDN
- Sentry + Datadog monitoring
How IRPR builds your scalable web app
We follow a 4-phase process: Idea, Roadmap, Product, Release.
Phase 1 (Idea) takes 1 week. We review your concept, user stories, and technical constraints. Phase 2 (Roadmap) takes 1 week. We produce a fixed-price proposal with wireframes, architecture diagram, and a 12-week timeline.
Phase 3 (Product) takes 8-10 weeks. Our senior engineers build the app in 2-week sprints. You see a working demo every sprint. Phase 4 (Release) takes 1 week. We deploy to production, set up monitoring, and hand over the code.
What ships with every scalable web app project
Every deliverable is production-ready and fully documented.
We do not hand over a half-finished prototype. Every project includes the full production setup: CI/CD pipeline, monitoring, error tracking, and infrastructure as code.
You get everything you need to run the app yourself or hand it to your internal team. No dependencies on IRPR after launch.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions
- Docker containers for local dev
- Infrastructure as code (Terraform or Pulumi)
- Sentry error tracking
- Datadog performance monitoring
- CloudWatch alerts and dashboards
- Postman API documentation
- User guide and admin guide
- Load test results from k6
