Top Custom Application Development DevelopersDevelopers
We build production-grade apps in 8-12 weeks. Fixed pricing from $80K with full ownership and compliance.
IRPR is a team of senior engineers who build custom web and mobile applications using modern stacks like React, Next.js, Node.js, Python, React Native, and Flutter. We ship production-ready software that scales from day one.
Every project follows a fixed-price model: after the 2-week Roadmap phase, you get a firm quote between $80,000 and $250,000. Delivery takes 8-12 weeks, and we handle compliance requirements like HIPAA, PCI-DSS, and SOC 2 without extra charges.
We work with CTOs scaling their engineering capacity, founders launching MVPs, enterprise teams modernizing legacy systems, and product managers who need a reliable development partner. No offshore mismanagement, no hourly surprises.

Why IRPR ranks among top custom application development developers
We deliver more projects on time and on budget than any generic shop.
Our team of senior engineers (10+ years average experience) works exclusively on your project. No junior devs, no offshore contractors. That means fewer bugs, faster delivery, and code that passes security audits.
Since 2016 we have shipped over 200 custom applications across 50 countries. Our on-time rate is 98%, and every project includes automated testing, CI/CD, and monitoring from day one.
How IRPR differs from typical custom app developers
The difference is measurable: fixed pricing, senior engineers, and compliance built-in.
Most agencies bill by the hour, change scope midway, and disappear after launch. We do the opposite. Every project begins with a two-week Roadmap phase where we define the full scope, tech stack, and fixed price.
You get weekly demos, a dedicated project manager, and full code ownership. No license fees, no hidden costs, no vendor lock-in.
- Hourly billing with rate escalation
- Vague delivery dates
- No compliance knowledge
- Offshore teams with time zone lag
- Code ownership unclear
- Scope creep from vague requirements
- Fixed price from $80K
- 8-12 week delivery guarantee
- HIPAA, PCI, SOC 2 built-in
- US-based senior engineers
- Full code ownership in your repo
- Weekly demos with clear milestones
Our 4-phase process to build your custom application
We turn your concept into a live, deployable product in 12 weeks or less.
Every project follows a structured four-phase approach. Each phase has clear deliverables and a go/no-go checkpoint to keep your investment safe.
From idea validation to production deployment, you always know where you stand.
