Why Scalable Web App Development Matters
Scaling isn't just about traffic - it's about reliability and cost control.
A web app that works for 100 users often breaks at 10,000. IRPR builds for scale from day one, using load balancing, caching, and database sharding.
Our clients see zero downtime during traffic spikes. We test at 10x expected load before launch to guarantee performance.
Generic Dev Shop vs IRPR
Most agencies deliver code that breaks under load. We don't.
Generic shops build monolithic apps that are cheap to start but expensive to scale. You hit a wall at 1,000 users and need a rewrite.
IRPR designs for scale from the first line of code. We use microservices or modular monoliths, automated CI/CD, and load testing at 10x traffic.
- Hourly billing
- No scalability testing
- Monolithic architecture
- No CI/CD
- Unknown uptime
- Code ownership unclear
- Fixed price
- Load testing at 10x scale
- Microservices or modular monolith
- Automated CI/CD
- 99.9% uptime guarantee
- Full code ownership
Our Scalable Web App Process
We follow a structured 4-phase approach to deliver production-ready apps in 8-12 weeks.
Every phase is designed to de-risk your project. You see working software every 2 weeks and can change direction without penalty.
We start with a Roadmap phase to lock scope, price, and timeline. Then we build, test, and deploy with full transparency.
What Ships with Every Scalable Web App
Every project includes these deliverables by default. No extra fees.
- Source code in your GitHub repo
- CI/CD pipeline with GitHub Actions
- Automated test suite (unit, integration, e2e)
- Database schema and migrations
- API documentation (Swagger/OpenAPI)
- Performance and load test reports
- Monitoring and alerting (Datadog, Sentry)
- Deployment runbook
- Admin dashboard
- User authentication (Auth0 or custom)
What we ship in this practice.
Marketplace for Freelancers
Built a two-sided marketplace using Next.js, PostgreSQL, and Stripe. Reduced transaction processing time by 40% and handled 50,000 concurrent users during launch.
Healthcare Patient Portal
Developed a HIPAA-compliant portal with React and AWS. Cut patient check-in time from 15 minutes to 3 minutes.
E-commerce Platform
Migrated a legacy Magento store to a custom Next.js and Shopify integration. Page load time dropped from 8s to 1.2s, increasing conversion by 25%.
Real-time Collaboration Tool
Built a WebSocket-based collaboration app using Node.js and Redis. Supported 10,000 simultaneous editors with under 100ms latency.
Fintech Dashboard
Created a real-time financial dashboard with React, D3.js, and AWS Lambda. Reduced data refresh latency from 30 seconds to under 2 seconds.
Logistics Tracking System
Designed a shipment tracking system with React Native and GraphQL. Reduced manual tracking effort by 80% and improved delivery accuracy.
Why teams hire us.
Fixed Price, Not Hourly
Every project gets a fixed quote after the Roadmap phase. No surprise invoices or scope creep charges.
Senior Engineers Only
Our team consists of senior engineers with 10+ years of experience. No junior devs, no handoffs.
8-12 Week Delivery
We deliver production-ready apps in 8 to 12 weeks. Our process is optimized for speed without sacrificing quality.
Full Code Ownership
You own 100% of the code and all assets. We transfer everything to your GitHub repository at launch.
99.9% Uptime Guarantee
We design for high availability with multi-region deployments and automated failover. Our apps maintain 99.9% uptime.
Scalability Built In
We load test at 10x expected traffic and use auto-scaling groups. Your app handles spikes without manual intervention.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
