Why hire expert custom application development consultants?
Our track record speaks for itself.
Every project we deliver is built by senior engineers with an average of 15 years of experience. We have shipped over 200 custom applications across 50 countries, with 98% on-time delivery and 99.9% uptime in production.
Our fixed-price model eliminates budget surprises. After the Roadmap phase, you know exactly how much the project costs and when it ships. No hourly billing, no scope creep.
Expert consultants vs generic dev shops
Here's the difference.
Most development shops rely on junior staff, vague timelines, and hourly billing. That leads to missed deadlines, hidden costs, and code you can't maintain.
IRPR works differently. We assign only senior engineers, lock a fixed price, and ship production-ready software in 8-12 weeks. You own the code from day one.
- Vague timelines
- Hourly billing with unlimited overages
- Junior developers (1-3 years)
- No compliance expertise
- Siloed work with slow feedback
- IP restrictions on code
- Fixed price locked after Roadmap
- 8-12 week delivery
- Senior engineers (15+ years avg)
- Built-in HIPAA, PCI-DSS, SOC 2
- Weekly demos and async standups
- Full code ownership in your repo
Our consulting process: from idea to release
We follow a proven 4-phase approach to deliver your custom app on time and on budget.
In the first two weeks we define your product roadmap, tech stack, and a fixed price. Then our senior engineers design, build, and deploy your application with continuous feedback cycles.
By week 8-12 you have a production-ready MVP with CI/CD, tests, monitoring, and documentation. No hand-waving, no delays.
What ships with every project
Everything you need to go live and maintain your app.
We deliver more than code. Every project includes the full toolchain so your team can take over without friction.
- Source code in your private GitHub/GitLab repo
- CI/CD pipeline (GitHub Actions or CircleCI)
- Cloud infrastructure as code (Terraform or AWS CDK)
- Unit, integration, and end-to-end tests (Jest, Cypress)
- Performance and security audit report
- Sentry error tracking and monitoring
- Post-launch support for 3 months
- Technical documentation and architecture diagrams
- 2-hour handoff session with your team
