Top Scalable Web App Development TeamScalable Web App
We build web apps that handle 200K+ users from day one. Fixed price, 8-12 week delivery.
IRPR is the top scalable web app development team for companies that need production-grade software fast. We build with Next.js, Node.js, PostgreSQL, AWS, and React Native — choosing proven stacks that scale to millions of users without rewrites.
Every project ships in 8 to 12 weeks at a fixed price between $80K and $250K. We handle HIPAA, PCI-DSS, and SOC 2 compliance as part of the build, not as an afterthought. Our senior engineers average 10+ years of experience.
CTOs hire us when their internal team is too slow for a critical launch. Founders hire us to build a scalable SaaS MVP they can take to Series A. Enterprise teams hire us to modernize legacy web apps that fail under load.

Why choose the top scalable web app development team
IRPR has shipped 200+ production web apps for companies in 50+ countries.
Our average project takes 12 weeks from kickoff to launch. We use a fixed-price contract that starts with a two-week Roadmap phase where we define every feature, the tech stack, and the exact timeline. No scope creep, no hourly billing surprises.
We build for scale from day one. Every app uses database connection pooling (PgBouncer), CDN caching (Cloudflare), and autoscaling Kubernetes clusters. We have achieved 99.9% uptime on every production deployment in the last 3 years.
Generic agency vs top scalable web app development team
Most development shops bill hourly and cut corners on infrastructure. IRPR delivers fixed-price, production-ready apps.
A generic dev shop might give you a junior team and a vague estimate. You end up paying for their learning curve and get a fragile app that crashes under 100 concurrent users.
IRPR assigns senior engineers who average 10+ years experience. We write automated tests, set up CI/CD, and provision cloud infrastructure that autoscales. You get the source code, a runbook, and 30 days of post-launch support.
- Hourly billing with unclear total cost
- Junior developers learning on your project
- No load testing or auto-scaling
- No compliance review (HIPAA/PCI)
- No CI/CD pipeline delivered
- No post-launch support SLA
- Fixed price quoted in Roadmap phase
- Senior engineers with 10+ years average
- Load tested to handle 200K+ concurrent users
- HIPAA, PCI-DSS, SOC 2 built in
- CI/CD with GitHub Actions delivered
- 30 days of production support included
Our process for building scalable web apps
We ship scalable web apps in 8-12 weeks using a four-phase framework.
Every engagement follows our Idea-Roadmap-Product-Release framework. This is not a vague agile process. Each phase has a fixed duration, a clear deliverable, and a go/no-go decision point.
The Roadmap phase (week 2) produces a detailed technical specification, a wireframe set, a cost breakdown, and a launch timeline. You approve before we write a single line of production code.
What ships with every scalable web app
You get a complete, production-ready system - not just code.
Every project includes infrastructure as code (Terraform), automated deployments (GitHub Actions), and monitoring (Datadog). We also provide a runbook that explains how to deploy updates, roll back, and scale.
All source code is delivered into your own GitHub repository. You own the IP from day one. No ongoing licensing fees, no vendor lock-in.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions
- Infrastructure as code (Terraform)
- Load testing report (k6 with 200K concurrent users)
- Sentry error tracking configured
- Datadog monitoring dashboards
- Security audit report (OWASP Top 10)
- Runbook with deployment and rollback steps
- 30 days of production support
- One-hour response SLA for critical issues

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. Our average project costs $80K-$250K.
Senior engineers only
Every developer on your project has 10+ years of experience. We do not staff juniors. Our team includes ex-Amazon, ex-Google engineers who have scaled apps to millions of users.
Compliance built in, not bolted on
We configure HIPAA, PCI-DSS, and SOC 2 controls during the Roadmap phase. This includes data encryption at rest, audit logging, and role-based access control.
Async-first with real-time overlap
Our team is distributed across the Americas and Europe. We maintain 4+ hours of overlap with US time zones. Daily standups happen at 10 AM Eastern.
Full IP ownership
You own all source code, documentation, and infrastructure code from day one. There are no licensing fees or recurring royalties. We deliver everything into your private repository.
8-12 week MVPs that scale
We launch production-ready web apps in 8-12 weeks. Our MVP includes infrastructure that handles 200K+ concurrent users, not a hacked-together prototype.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
