Scale without limits with expert web app development
Our architecture scales from zero to millions of users without manual intervention.
Every web app we build uses horizontal auto-scaling on AWS ECS or Kubernetes. We configure target tracking alarms to add instances when CPU exceeds 70%. Your app scales up during traffic peaks and down during lulls to control costs.
We also use CloudFront CDN for static assets, Redis for session caching, and RDS read replicas to handle query spikes. Our load testing with k6 confirms your app can handle 10x your projected traffic before launch.
Why generic dev shops fail at scalability
Most development teams build monolithic apps that break under load. IRPR architects for scale from day one.
A typical dev shop deploys a single server and adds servers manually when problems arise. That approach causes downtime and bad user experience during traffic spikes.
IRPR uses multi-region AWS, auto-scaling groups, CDN caching, and microservices from the first commit. We load test every sprint and monitor with Datadog to catch bottlenecks early.
- Single server deployment
- No load testing
- No caching strategy
- Manual scaling only
- Monolithic codebase
- No production monitoring
- Multi-region AWS or GCP architecture
- Automated load testing with k6 every sprint
- CDN caching (CloudFront, Cloudflare)
- Auto-scaling with Kubernetes
- Microservices or modular monolith
- Sentry + Datadog monitoring from day one
Our 4-phase process to build your scalable web app
We ship fast without cutting corners.
Each phase has clear deliverables and a fixed timeline. The result is a production-ready web app in 8-12 weeks.
We keep you informed with sprint demos and a shared roadmap. Changes are easy to make during the first two weeks.
What ships with your scalable web app
Every project includes these deliverables.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Auto-scaling infrastructure code (Terraform)
- Load testing results (k6 report)
- API documentation (Swagger)
- Sentry error tracking integration
- Datadog performance dashboards
- Deployment runbook
- Penetration test summary (if compliance required)
- 30-day post-launch support
What we ship in this practice.
HealthTech Telehealth Portal

Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote during the Roadmap phase (week 2). No hourly billing, no surprise invoices. Our 200+ projects average 8-12 weeks delivery on budget.
Senior engineers only
No juniors, no offshore farms. Every engineer has 8+ years experience with Node.js, React, and AWS. Your team stays the same throughout the project.
Production-ready from day one
We don't build prototypes. Your app ships with CI/CD, monitoring, auto-scaling, and error tracking configured. Most clients hit 99.9% uptime from launch.
Security and compliance built in
We implement SOC 2, HIPAA, PCI-DSS, or ISO 27001 controls during development. No retrofitting. Includes penetration testing and compliance documentation.
Full code ownership
You own all source code, devops scripts, and documentation. No licensing fees, no vendor lock-in. We deploy to your AWS or GCP account.
30-day post-launch support
After launch, we monitor errors, fix bugs, and handle scaling adjustments for 30 days. Response time under 4 hours during business hours.
