Why IRPR is the top custom application development company
We combine senior engineering talent with fixed-price predictability.
IRPR has shipped 200+ custom applications across 50+ countries. Our engineers average 10+ years of experience each. Every project includes automated testing, CI/CD, and real error monitoring from day one.
We quote a fixed price during the Roadmap phase (week 2). No hourly billing. No surprises. You know the full cost before we write production code.
The IRPR difference compared to other development shops
We are not a body shop. Every project has a dedicated senior team and a fixed budget.
Most agencies bill hourly and hand off junior developers halfway through. IRPR assigns a senior team that stays for the full project. Our Roadmap phase locks scope and price so you never pay for surprises.
We ship your source code in your own GitHub repo on day one. No black boxes. No ongoing license fees. You own everything, and we help you deploy on your AWS account.

How we build your custom application in 4 phases
From idea to launch, we use a proven process that removes guesswork.
Every project starts with a 1-week Discovery phase where we map your requirements, users, and data flows. Then we create a detailed Roadmap with wireframes, architecture, and a fixed price quote.
The Build phase runs in 2-week sprints with daily standups and a shared Slack channel. At the end of each sprint you see working software. The Release phase includes automated deployment, performance testing, and a 30-day warranty.
What ships with every custom application from IRPR
You get more than just code. Every project includes the full production toolchain.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions or GitLab CI
- Error tracking with Sentry
- Application monitoring with Datadog or Grafana
- Unit and integration test suite (coverage > 80%)
- Deployment scripts for AWS, GCP, or Azure
- API documentation with Swagger or Postman
- Admin dashboard for managing users and data
- Security audit report (OWASP top 10)

Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges.
Senior engineers only
Our average engineer has 10+ years of experience. We never outsource or staff juniors. You work directly with the team building your app.
Compliance built in
We handle HIPAA, PCI-DSS, SOC 2, and FERPA compliance as part of the architecture. No separate security audit required before launch.
8-12 week MVPs
From kickoff to production, your MVP ships in 8-12 weeks. We run 2-week sprints with a demo at the end of each sprint.
Full code ownership
You own all source code, documentation, and infrastructure from day one. No licensing fees or lock-in. We deploy on your AWS account.
Async-first, reliable communication
We work async with daily standups and a shared Slack channel. Overlap hours cover US time zones. No micromanagement needed.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
