What you get with our scalable web apps
We ship production-ready code that handles growth from day one.
Every app we build uses infrastructure-as-code with Terraform, auto-scaling groups on AWS ECS or Azure Kubernetes, and a CDN via CloudFront or Cloudflare. We configure database read replicas and caching layers (Redis, Memcached) to handle traffic spikes without downtime.
Your team gets full ownership of the GitHub repository, CI/CD pipeline, and monitoring dashboards (Datadog/Sentry). We also document the architecture decision records (ADRs) and run load tests with k6 to prove scalability before launch.
How IRPR differs from generic developers
Most freelance contractors build websites. We build platforms that scale.
Generic developers often deliver WordPress sites or simple CRUD apps that break at 100 users. They have no experience with horizontal scaling, database sharding, or compliance certifications.
IRPR senior engineers have shipped apps handling 1M+ monthly active users. We write automated tests (80%+ coverage), set up zero-downtime deployments, and guarantee fixed timelines.
- Hourly billing surprises
- No scalability planning
- Single developer bottleneck
- No CI/CD setup
- Zero load testing
- Slack-only communication
- Fixed price per project
- Auto-scaling architecture
- Dedicated 3-4 person team
- GitHub Actions pipeline
- k6 load testing before launch
- Weekly progress reports
Our process for scalable web app development
We move from idea to production in four phases.
Phase 1: Idea validation and technical feasibility. We review your requirements, wireframes, and data model to ensure the architecture supports growth. This takes one week.
Phase 2: Roadmap with fixed scope and fixed price. You get a detailed sprint plan with deliverables, milestones, and the exact cost. No changes without a change order.
What ships with every scalable web app
You get more than code and a domain.
Every engagement includes production infrastructure, automated testing, and post-launch support. We don't disappear after deployment.
- Full source code in your private GitHub repository
- CI/CD pipeline using GitHub Actions
- Automated test suite with 80%+ coverage (Jest, Cypress)
- Dockerized development environment
- Terraform scripts for infrastructure
- Sentry error and performance monitoring
- Datadog dashboard for logs and metrics
- Load test report from k6 (1,000+ concurrent users)
- Architecture Decision Records (ADRs) documentation
- Two weeks of post-launch production support

Full code ownership
You own every line of code, every Docker image, every Terraform script. No proprietary platforms, no lock-in. Your code runs on your own AWS account from day one.
Compliance built in
We handle HIPAA, PCI-DSS, SOC 2, FERPA, and ISO 9001 compliance during development. No afterthought security audits. We build audit logs and encryption from the first sprint.
Transparent progress
You get a live demo every two weeks. We use Linear for task tracking and Slack for daily standups. Every sprint we show you working software, not slide decks.
