Why Choose IRPR as Your Custom Web App Development Vendor
We deliver production-grade web apps that meet compliance standards and ship on time.
Over the past 6 years, IRPR has shipped 200+ custom web applications across 50+ countries. Our senior engineers average 10+ years of experience. Every project has a dedicated project manager and weekly client demos.
We maintain a 98% on-time delivery record and a 99.9% uptime guarantee post-launch. Our fixed-price model means no cost overruns. We start every engagement with a 2-week Roadmap phase to define scope exactly.
How IRPR Differs from Other Custom Web App Development Vendors
You get senior talent, fixed pricing, and compliance built in from day one.
Most development shops use hourly billing and junior developers. They often miss compliance requirements and produce code you don't fully own. IRPR takes a completely different approach.
We assign only senior engineers (10+ years average), offer fixed project pricing, and deliver full source code ownership. Every project includes CI/CD, monitoring, and a compliance checklist for HIPAA, PCI-DSS, or SOC 2.
- Hourly billing leads to budget overruns
- Junior devs with 2-3 years experience
- No compliance expertise (HIPAA, PCI)
- Code often stays with agency
- Post-launch support is an extra contract
- Timelines slip by 30-50% frequently
- Fixed price, no overruns
- Senior engineers with 10+ years experience
- HIPAA, PCI-DSS, SOC 2 compliance built in
- Full code ownership in your repo
- Post-launch support included in initial contract
- 12-week average delivery, 98% on-time rate
Our Custom Web App Development Process
From idea to release in 8-12 weeks, with full transparency at every stage.
We use a four-phase process: Idea, Roadmap, Product, Release. Each phase has clear deliverables and a go/no-go checkpoint. You know exactly what you're getting before any large build.
In the Roadmap phase (week 2), we deliver a complete product specification and a fixed price. If you don't like the plan, you pay only for that phase and walk away.
What Ships with Every Custom Web App
More than just code. You get a production-ready system designed for scale.
Every IRPR project includes infrastructure, monitoring, and documentation. You don't need to hire a separate DevOps person. We set everything up before launch.
Your team receives all credentials, architecture diagrams, and a runbook. We also provide a handover session with your internal developers.
- Full source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions or AWS CodePipeline
- Sentry error tracking and performance monitoring
- Load tested for expected traffic (2x estimate)
- Database schema documentation (Entity Relationship Diagram)
- API documentation (OpenAPI or GraphQL schema)
- Docker containers for local development
- Pre-prod and staging environments

- 30-day post-launch support with 4-hour response SLA
