Senior Scalable Web App Development ServicesScalable Web App
We build web applications that handle 10x traffic without breaking. Fixed price, senior engineers, and a 12-week MVP timeline.
IRPR builds senior scalable web app development services for companies that need production-grade applications from day one. We use React, Next.js, Node.js, PostgreSQL, and cloud infrastructure on AWS or Azure to deliver apps that scale horizontally under load.
Every project ships within 12 weeks for the MVP phase, with a fixed price between $80,000 and $250,000. We comply with HIPAA, PCI-DSS, SOC 2, and GDPR standards depending on your industry.
Our typical buyers are CTOs at Series A startups who need a scalable platform before raising Series B, engineering directors at enterprises replacing legacy systems, and product managers at mid-market companies launching a new SaaS product with high traffic expectations.

Why Scalable Architecture Matters for Your Web App
A web app that works for 100 users will crash at 1,000 if it is not built for scale from the start.
We design every application with horizontal scaling in mind. Our architecture uses stateless services, database read replicas, and CDN caching to handle traffic spikes without manual intervention. We have shipped over 200 applications that serve users in 50+ countries.
For example, a fintech client we built a payment dashboard for processes 500,000 transactions per month with 99.9% uptime. The app auto-scales on AWS ECS during peak hours and compresses to 2 instances during low traffic, saving the client $4,000 per month in infrastructure costs.
Generic Dev Shop vs. IRPR: The Difference in Scalable Web App Delivery
Not all development teams build for scale. Here is how IRPR differs from a generic agency.
Generic dev shops often use junior developers, hourly billing, and no fixed scope. They deliver a working app but it breaks under load, costs more than quoted, and takes twice as long.
IRPR assigns only senior engineers with 10+ years of experience. We use fixed pricing from the Roadmap phase (week 2), ship the MVP in 12 weeks, and include load testing and auto-scaling by default.
- Junior developers with 0-3 years experience
- Hourly billing with no cap
- No load testing in scope
- Single server deployment
- No CI/CD pipeline
- No monitoring or alerting
- Senior engineers with 10+ years experience
- Fixed price from Roadmap phase
- Load testing to 10x target traffic
- Auto-scaling on AWS or Azure
- CI/CD on GitHub Actions
- Sentry and CloudWatch monitoring
Our 4-Phase Process for Senior Scalable Web App Development
From idea to release in 12 weeks, with fixed pricing and full transparency.
Every engagement follows the same four phases. You know the cost, timeline, and deliverables before we write a single line of code.
We have refined this process across 200+ projects. It eliminates scope creep and ensures the app is production-ready at launch.
What Ships With Every Senior Scalable Web App
Every project includes these deliverables. No hidden fees, no missing pieces.
We believe in full transparency. Every deliverable is listed in the Roadmap phase, and we hold to it.
Source code, infrastructure, and documentation are yours. We do not license or restrict access.
- Source code in your private GitHub repository
- CI/CD pipeline on GitHub Actions with automated tests
- Infrastructure as code (Terraform or CloudFormation)
- Auto-scaling configuration for AWS or Azure
- Load test results showing 10x target traffic handling
- Sentry error tracking and CloudWatch monitoring
- Comprehensive API documentation (Postman or Swagger)
- 1-year warranty on all code

Why teams hire us.
Fixed Price, Not Hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the total cost before we build.
Senior Engineers Only
We hire only engineers with 10+ years of experience. No junior developers, no outsourcing, no code quality issues. Every line of code is written by a senior developer.
12-Week MVP Timeline
We ship a production-ready MVP in 12 weeks. This is not a prototype. It is a fully scalable, tested, and deployed application that handles real traffic.
Full Code Ownership
You own the source code, the infrastructure, and the documentation. We do not license, restrict, or charge royalties. The code is yours to deploy anywhere.
Compliance Built In
We build HIPAA, PCI-DSS, SOC 2, and FERPA compliant applications. Compliance is not an add-on. It is part of the architecture from day one.
1-Year Warranty
Every project includes a 1-year warranty on all code. If a bug appears, we fix it at no cost. We stand by our work for 12 months after release.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
