Why hire a professional scalable web app development firm
Building a web app that scales is not about adding more servers. It is about architecture decisions made in week one.
IRPR starts every project with a 2-week Roadmap phase. We define data models, API contracts, and deployment architecture before writing a single line of production code. This phase costs $8,000 and includes a fixed-price quote for the full build.
Our senior engineers use React or Next.js for the frontend, Node.js or Python for the backend, and PostgreSQL for the database. We deploy on AWS with auto-scaling groups and RDS Multi-AZ. Every app ships with error tracking via Sentry and uptime monitoring via Datadog.
The difference between IRPR and a generic dev shop
Most agencies promise scalable apps but deliver monoliths that break under load. IRPR builds for scale from day one.
A generic dev shop might use a junior team, skip load testing, and hand over code without documentation. You end up with technical debt and no way to scale.
IRPR assigns senior engineers only. Every project includes load testing with k6, automated CI/CD pipelines, and a deployment runbook. You get a scalable web app that handles 10x traffic without changes.
- Junior developers with 1-2 years experience
- No load testing before launch
- Monolithic architecture from the start
- No CI/CD pipeline, manual deployments
- No documentation or runbook
- Hourly billing with scope creep
- Senior engineers with 8+ years experience
- Load testing with k6 in the Roadmap phase
- Microservices or modular monolith based on needs
- CI/CD pipeline on GitHub Actions from week 1
- Full deployment runbook and architecture docs
- Fixed price with no surprises
How IRPR builds your scalable web app
Our process has 4 phases. Each phase ends with a deliverable you can review and approve.
Phase 1 is Idea. We clarify your requirements and create a product brief. Phase 2 is Roadmap. We define the architecture, tech stack, and fixed-price quote.
Phase 3 is Product. Our team builds the MVP in 8-12 weeks with weekly demos. Phase 4 is Release. We deploy to production, set up monitoring, and hand over source code.
What ships with every scalable web app
Every project includes these deliverables by default. No hidden costs or optional add-ons.
You get more than just code. IRPR provides everything needed to run, monitor, and maintain your web app from day one.
Our checklist ensures nothing is forgotten. You can verify each item during the handoff call.

- Sentry error tracking configured
- Datadog uptime and performance monitoring
- Load test results from k6
- Deployment runbook in Markdown
- Architecture diagram (draw.io)
- API documentation (Swagger/OpenAPI)
- Admin panel with user management
