Why IRPR Delivers the Best Custom Web App Development Services
Our track record speaks for itself. Here are the numbers behind 200+ successful web apps.
IRPR has shipped over 200 custom web applications for clients in 50+ countries. Our average project timeline is 12 weeks from kickoff to production release. 98% of projects deliver on time and on budget.
We maintain 99.9% uptime across all deployed applications using AWS multi-region architecture. Our clients see an average 40% reduction in infrastructure costs after we migrate their apps to serverless or containerized environments.
Generic Dev Shop vs IRPR: The Real Difference
Not all custom web app development services are equal. Here is how we compare.
Many agencies promise custom work but deliver cookie-cutter templates. They bill by the hour, change scope without notice, and hand you code with no tests or documentation.
IRPR operates differently. We give you a fixed price in week 2, write automated tests for every endpoint, and deploy with CI/CD on day one. You own the code and the infrastructure.
- hourly billing with no cap
- no written specification
- zero automated tests
- deploy on your own after launch
- no compliance knowledge
- code ownership unclear
- fixed price from Roadmap phase
- detailed spec with user stories
- 90%+ test coverage on backend
- CI/CD pipeline with GitHub Actions
- HIPAA, PCI-DSS, SOC 2 ready
- full source code ownership
Our Custom Web App Development Process
We follow a four-phase process that eliminates surprises and delivers working software fast.
Every project starts with a 2-week Roadmap phase where we define scope, architecture, and a fixed price. No ambiguity, no hidden costs.
Then we build your MVP in 8-12 weeks using agile sprints. You see progress every week and can adjust priorities. After launch, we support you with monitoring, maintenance, and scaling.
What Ships With Every Custom Web App
Every project includes these deliverables. No extra charges, no surprises.
When you choose IRPR for custom web app development services, you get more than code. You get a fully operational system ready for production traffic.
Our standard delivery includes source code, infrastructure as code, automated tests, and deployment pipelines. Everything is documented and handed over.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Automated test suite (unit, integration, e2e)
- Infrastructure as code (Terraform or CDK)
- Sentry error tracking with alerts
- Datadog monitoring dashboard
- API documentation (Swagger/OpenAPI)
