Scalable Web App Development CompanyWeb App
Build a web app that handles 10x growth from day one. 200+ products shipped in 12 weeks on average.
IRPR builds scalable web apps using React, Next.js, Node.js, and PostgreSQL on AWS or GCP. We design for horizontal scaling from the first commit so your app handles traffic spikes without rewrites.
We ship production-ready web apps in 8-12 weeks with fixed pricing between $80K and $250K. Every project includes CI/CD, monitoring with Sentry, and load testing to verify scalability targets.
Founders launching a SaaS platform hire us to build a scalable MVP. CTOs at mid-market companies hire us to replace legacy monoliths. Product managers at enterprise firms hire us to build internal tools that serve thousands of users.

Why choose a scalable web app development company
Scalability is not an add-on. It is built into the architecture from the start.
Most web apps fail under load because the code was written for a few hundred users. IRPR designs every app with horizontal scaling in mind. We use stateless APIs, database read replicas, and CDN caching so your app handles 10,000 concurrent users without crashing.
We also load test every app before launch using k6 or Artillery. In 2024, 98% of our deployed apps maintained 99.9% uptime during peak traffic. You get a web app that grows with your revenue, not a rewrite project six months later.
Generic dev shop vs IRPR
Not all agencies build for scale. Here is what you actually get.
A generic dev shop might deliver a working app that buckles at 500 users. They often use shared hosting, no CI/CD, and no monitoring. You end up paying for emergency scaling later.
IRPR treats scalability as a requirement from day one. We use AWS or GCP auto-scaling groups, database connection pooling, and Redis caching. Every project includes a scalability test report before launch.
- No load testing before launch
- Single server deployment
- No database indexing plan
- No CDN for static assets
- No monitoring or alerting
- Hourly billing with scope creep
- Load tested with k6 before go-live
- Auto-scaling on AWS or GCP
- Database read replicas and connection pooling
- CloudFront or Cloud CDN configured
- Sentry error tracking and PagerDuty alerts
- Fixed price with no surprise invoices
How we build your scalable web app
Our process from idea to release is designed to de-risk every phase.
We start with a two-week Roadmap phase where we define the architecture, data model, and scalability plan. You get a fixed price quote and a Gantt chart before any code is written.
Then we build in two-week sprints with weekly demos. You see the app grow and can adjust priorities. By week 8-12, you have a production-ready web app deployed on your own AWS or GCP account.
What ships with every web app
You own everything. No black boxes, no hidden dependencies.
Every project includes the full source code in your private GitHub repository. We set up CI/CD pipelines on GitHub Actions so you can deploy changes after we leave.
We also configure monitoring with Sentry and uptime checks with Better Uptime. You get a runbook with commands for scaling, backups, and incident response.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Staging and production environments on AWS or GCP
- Auto-scaling group configuration
- Database with read replicas and automated backups
- Sentry error tracking and performance monitoring
- Load test report with k6 results
- Deployment runbook with 15 commands
- Admin dashboard for managing users and data
- Stripe or payment gateway integration
