Top Scalable Web App Development ServicesWeb App
We build web apps that handle millions of users without breaking. 12-week MVPs with fixed pricing, delivered by senior engineers only.
IRPR is a software development studio that provides top scalable web app development services. We build web applications using React, Next.js, Node.js, Python, Go, and cloud infrastructure on AWS or GCP with auto-scaling, load balancing, and CDN out of the box.
Every project starts with a fixed-price Roadmap phase (week 2) where we define the architecture. MVPs ship in 8-12 weeks. Full enterprise web apps typically range from $80K to $250K depending on complexity. We comply with HIPAA, PCI-DSS, SOC 2, and FERPA.
We work with founders who need a scalable MVP to raise Series A, CTOs modernizing legacy monoliths into microservices, and enterprise teams launching high-traffic customer portals. Each gets a dedicated team of 3-5 senior engineers.

Why Scalable Web App Architecture Matters
A web app that crashes at 1,000 concurrent users is not a web app. It is a liability.
We design every web app to handle 10x your initial traffic estimate. Our default stack uses Next.js for server-side rendering, AWS ECS with auto-scaling, and a caching layer with Redis and CloudFront CDN. This architecture supports 50,000 concurrent users without re-architecting.
For enterprise clients, we add blue-green deployments, database read replicas, and horizontal scaling for both compute and storage. We have shipped apps that grew from 1,000 to 10 million monthly active users without a rewrite.
Generic Dev Shop vs IRPR
Not all web development services are built to scale. Here is what you avoid with IRPR.
Most dev shops start coding without an architecture plan. They use a single server, no caching, and no CI/CD. When traffic spikes, the app goes down and you pay for emergency fixes.
IRPR starts with a Roadmap phase where we define the data model, API contracts, and cloud infrastructure. We use Terraform for infrastructure as code, GitHub Actions for CI/CD, and Datadog for monitoring. Your app is production-ready from day one.
- No architecture plan before coding
- Single server deployment
- No load testing
- Hourly billing with scope creep
- No monitoring or alerting
- Code ownership unclear
- Fixed-price Roadmap with full architecture
- Auto-scaling cloud infrastructure (AWS/GCP)
- Load testing with k6 before launch
- Fixed price, no surprise invoices
- Datadog monitoring and Sentry error tracking
- You own 100% of the source code
Our 4-Phase Process for Scalable Web Apps
Every project follows the same predictable process: Idea, Roadmap, Product, Release.
Phase 1 (Idea) takes 1 week. We review your business goals, target users, and core features. You get a product brief with user stories and a technical feasibility assessment.
Phase 2 (Roadmap) takes 1 week. We deliver a fixed-price proposal with wireframes, data model, API design, cloud architecture diagram, and a 12-week build timeline. You approve before any coding starts.
What Ships With Every Scalable Web App
Every project includes production-ready infrastructure, not just code.
We do not hand off a zip file. You get a fully deployed application with monitoring, CI/CD, and documentation. Your team can take over maintenance immediately or we provide ongoing support.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Auto-scaling cloud infrastructure (AWS or GCP)
- Database with automated backups (PostgreSQL)
- Redis caching layer for high performance
- CDN for static assets (CloudFront)
- Sentry error tracking and alerting
- Datadog monitoring dashboard
- Load test report (k6 with 10K concurrent users)
- Full technical documentation and API docs
