Expert Custom Application Development Agency by the Numbers
We have shipped over 200 custom applications for clients in 50 countries.
Our team of senior engineers averages 10+ years of experience. We focus on delivering production-ready code, not prototypes. Every project goes through a fixed-price Roadmap phase before any development starts.
We maintain a 98% on-time delivery rate and 99.9% uptime across all deployed applications. Our clients save an average of 4 months compared to hiring in-house because we start within 2 weeks.
Why Choose an Expert Custom Application Development Agency
Not all agencies deliver the same quality. Here is the difference between IRPR and a generic dev shop.
Generic agencies often use junior developers, charge hourly, and leave you with unclear ownership. They may skip compliance requirements and deliver code you cannot maintain.
IRPR assigns only senior engineers, works on fixed-price contracts, and hands over full source code. We include CI/CD, monitoring, and compliance documentation out of the box.
- Vague project estimates that change mid-build
- Hourly billing without a cap
- Junior developers with little oversight
- No compliance expertise (HIPAA, PCI, SOC 2)
- Unclear code ownership after project end
- Slow, email-only communication
- Fixed price locked after a 2-week Roadmap
- Senior engineers only (10+ years average)
- Built-in HIPAA, PCI-DSS, SOC 2 compliance
- Full source code ownership in your repo
- Async-first communication with daily standups
- 2-week kickoff from signed contract
Our Process for Expert Custom Application Development
We follow a proven 4-phase process to ensure on-time, on-budget delivery.
Each project starts with a fixed-price Discovery phase. We map out every feature, integration, and compliance requirement before a single line of code is written.
Development then runs in 2-week sprints with daily standups and a shared Jira board. Clients see progress every sprint and provide feedback via Slack or video calls.

Why teams hire us.
Fixed Price Guarantee
Every project gets a fixed quote after the 2-week Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges. If we discover new requirements mid-build, we adjust the scope before adding cost.
Senior Engineers Only
We do not use junior or offshore talent. Every engineer on your project has at least 10 years of experience with modern stacks like React, Node.js, Python, and AWS. You get a lead engineer who stays through the entire project.
Async-First Workflow
Our teams work in US-friendly time zones and communicate via Slack, Linear, and Loom. We do not require daily synchronous calls unless you want them. This speeds up development and reduces meeting overhead.
Compliance by Default
We build with HIPAA, PCI-DSS, and SOC 2 controls from day one. Our codebase includes encryption, audit logs, and access controls. No retrofitting compliance after launch.
Full Code Ownership
You get the entire source code in your GitHub repo. You own all copyrights, infrastructure credentials, and domain names. There is no vendor lock-in.
2-Week Kickoff
From signed contract to first sprint, you wait at most 2 weeks. We start the Roadmap phase immediately and deliver a fixed-price proposal by week 2.
