What senior scalable web app development consultants deliver
Every engagement starts with a clear roadmap and ends with a production-ready system.
IRPR's senior engineers have shipped over 200 web apps across 50 countries. We use React, Node.js, PostgreSQL, and AWS to build systems that scale from 1 user to 1 million without a major refactor.
Our process includes load testing, auto-scaling configuration, and database indexing from sprint one. We don't wait for traffic to break things - we design for scale upfront.
Why generic dev shops fail at scalable web apps
Most agencies promise scale but deliver spaghetti code that breaks under load.
Generic shops use junior developers, hourly billing, and no compliance expertise. They build for today's traffic, not tomorrow's growth. You end up with a rewrite bill that doubles your original cost.
IRPR assigns senior engineers only - no juniors. We write tests, set up CI/CD, and configure monitoring from day one. Your app is production-ready at launch, not after six months of fixes.
- Junior developers on your project
- Hourly billing with no cap
- No load testing until after launch
- No compliance (HIPAA/PCI/SOC2)
- Code you don't fully own
- Months of rewrites to scale
- Senior engineers only (8+ years avg)
- Fixed price from Roadmap phase
- Load testing in sprint 2
- Built-in HIPAA, PCI, SOC2 compliance
- Full code ownership from day one
- Scale-ready architecture from sprint 1
Our 4-phase process for scalable web apps
From idea to release in 8-12 weeks with no surprises.
Every project follows our proven framework: Idea, Roadmap, Product, Release. Each phase has clear deliverables and a fixed price.
We start with a 1-week discovery to define scope, then produce a detailed Roadmap with wireframes, tech stack, and timeline. The Product phase builds the MVP in 6-10 weeks. Release includes deployment, monitoring, and handover.
What ships with every scalable web app
No hidden deliverables. Everything you need to run and grow your app.
Every IRPR project includes the complete production stack. You don't pay extra for CI/CD, monitoring, or documentation.
We ship source code in your private GitHub repo, a fully configured CI/CD pipeline, and a deployment guide. Your team can take over immediately.
- Source code in your GitHub repo
- CI/CD pipeline (GitHub Actions)
- Sentry error tracking
- Datadog performance monitoring
- Load testing report (k6)
- Database migration scripts
- API documentation (Swagger)
- Deployment runbook
- 30-day post-launch support

Senior engineers only
Our team averages 8+ years of experience. No juniors, no outsourced code. Every line of code is written by a senior engineer who has shipped production apps at scale.
8-12 week MVPs
We ship a production-ready MVP in 8-12 weeks. That's fast enough to validate your idea and solid enough to raise your next round. 98% of our projects deliver on time.
Built-in compliance
We build HIPAA, PCI-DSS, SOC 2, and FERPA compliance into every project from sprint one. No afterthought audits, no retrofitting. Your app is audit-ready at launch.

You own 100% of the source code, IP, and documentation. We put everything in your GitHub repo. No lock-in, no licensing fees, no hidden restrictions.
Async-first, timezone-friendly
Our team works across 6 time zones with overlap hours for real-time sync. You get daily updates via Slack and weekly video calls. No 9-to-5 constraints.
