What top custom web app development consultants deliver
Our clients get a production-ready web app with code ownership, CI/CD, and compliance baked in.
Most consulting agencies hand you a prototype that needs rewriting. IRPR ships a real product. We set up your cloud infrastructure on AWS, configure CI/CD pipelines with GitHub Actions, and deploy to live environments. You own the source code from day one.
Every web app we build includes error monitoring with Sentry, performance tracking with Datadog, and automated backups. Our clients do not pay extra for these. They are part of our standard delivery.
How IRPR differs from other web app consultants
Not all consultants are the same. Here is what separates us from the rest.
Generic agencies assign junior developers, charge hourly, and deliver late. IRPR assigns senior engineers only with minimum 8 years experience. We work on a fixed price after the Roadmap phase.
We do not use outsourced teams or project managers who cannot code. Every IRPR consultant writes code, reviews code, and ships code. You talk directly to the team building your product.
- Junior or mid-level developers
- Hourly billing with time tracking
- No MVP timeline guarantee
- Code owned by agency
- Minimal documentation
- No compliance focus
- Senior engineers only (8+ years)
- Fixed price after Roadmap
- MVP in 8-12 weeks
- Full code ownership from start
- Comprehensive docs and architecture diagrams
- Built-in HIPAA, PCI-DSS, SOC 2, FERPA
Our process as top custom web app development consultants
We follow a clear four-phase process to turn your idea into a live product.
Every engagement starts with an Idea call where we map your requirements and create a user story map. By week 2 you get a Roadmap document with a fixed price quote and timeline. No surprises.
The Product phase builds your MVP in 8-12 weeks. We ship iteratively with weekly demos. After launch, we handle Release with monitoring, scaling, and ongoing support if needed.
What ships with every custom web app
Every project includes these deliverables by default. No hidden costs.
You get a production-ready web app with full source code, database schema, and deployment scripts. We also provide a runbook so your engineers can maintain the system without us.
- Source code in your private GitHub repo
- CI/CD pipeline using GitHub Actions
- AWS infrastructure as Terraform code
- PostgreSQL database with migrations
- Sentry error and performance monitoring
- Datadog for production observability
- Unit tests with 80%+ coverage
- API documentation via Swagger/OpenAPI
- Deployment runbook for your ops team
- 1 hour of knowledge transfer session
