Why Businesses Choose IRPR for Custom Application Development
Every custom app we build ships with predictable costs, senior engineering, and production-grade infrastructure.
IRPR has delivered over 200 custom applications across 50 countries. Our average MVP takes 12 weeks from kickoff to production. We use fixed pricing, so budgets are locked in after the Roadmap phase (week 2).
We build apps that meet strict compliance standards: HIPAA for healthcare, PCI-DSS for payments, SOC 2 for enterprise SaaS, and FERPA for edtech. Our senior engineers handle security, scalability, and performance from day one.
Custom Application Development: IRPR vs. Generic Shops
The difference is in the details: fixed pricing, senior engineers only, and full code ownership.
Many development agencies operate with hourly billing and junior-heavy teams. They often produce undocumented code, miss deadlines, and don't include post-launch support. IRPR is different.
We assign only senior engineers (7+ years experience). Every project has a fixed price, a clear Roadmap, and a dedicated project manager. You own the source code and all IP from day one.
- Hourly billing with no cap
- Junior-heavy teams (often 2-3 years exp)
- No fixed timeline, scope creep common
- You do not own the code without negotiation
- No compliance expertise (HIPAA, PCI, etc.)
- Post-launch support billed separately
- Fixed price quoted in week 2
- Senior engineers only (7+ years average)
- 8-12 week delivery with weekly milestones
- Full source code ownership from day one
- HIPAA, PCI-DSS, SOC 2 compliance built in
- Post-launch monitoring and 1-year warranty
Our Custom Application Development Process
We follow a four-phase process that eliminates surprises and keeps your project on track.
Every engagement starts with a Discovery phase where we map your requirements, tech stack, and compliance needs. By the end of week 2, you have a detailed Roadmap with fixed price and timeline.
We then build in 2-week sprints, delivering a testable increment every iteration. You review, give feedback, and see real progress. After launch, we monitor the app and fix any issues for one full year.
What Ships With Every Custom Application
Every project includes production-grade infrastructure, documentation, and ongoing support - no hidden extras.
We don't just hand over code. Every custom app comes with a fully configured CI/CD pipeline, automated tests, and production monitoring. You get a dashboard where you can see uptime, error rates, and user activity.
All code is delivered with documentation, architecture diagrams, and deployment scripts. We also include a one-year warranty on all code we write - if something breaks, we fix it at no cost.
- Source code in your private repository (GitHub/GitLab/Bitbucket)
- CI/CD pipeline with GitHub Actions or GitLab CI
- Sentry error tracking and performance monitoring
- Automated unit, integration, and end-to-end tests
- Deployment to AWS, GCP, or Azure for production
- Post-launch monitoring dashboard (uptime, errors, traffic)
- Architecture documentation and API documentation (Swagger/Postman)
- One-year warranty on all custom code
- Admin panel or dashboard for managing users and data
- SSL/TLS configuration, DDoS protection, and secrets management
