Expert Custom Application Development FirmApplication Development
We build custom apps for your exact business needs in 8-12 weeks. Fixed price, senior engineers, no surprises.
IRPR is an expert custom application development firm that builds web apps, mobile apps, and AI-powered platforms using Next.js, React Native, Python, and cloud services like AWS and GCP. We ship production-grade code with CI/CD, monitoring, and full documentation.
Every project starts with a fixed-price Roadmap after a 1-2 week discovery. Typical builds run 8-12 weeks and cost $80K to $250K depending on complexity. We comply with HIPAA, PCI-DSS, SOC 2, and FERPA as needed.
Companies hire IRPR when they need a senior team fast: CTOs who want to de-risk their product roadmap, founders launching a SaaS MVP, enterprise teams modernizing legacy systems, and compliance officers who require auditable development.

Tech Stack Specific
Why choose an expert custom application development firm?
Most agencies reuse templates. We build every app from scratch for your exact requirements, with your preferred tech stack and compliance standards.
Generic development shops send you junior devs and charge by the hour. They deliver late and over budget. IRPR assigns senior engineers only, with an average of 8 years experience per developer. We use fixed pricing so you know the cost before we write a line of code.
Whether you need a HIPAA-compliant patient portal or a PCI-DSS payment gateway, we handle all compliance documentation and security audits. Our 98% on-time delivery rate means your product launches on schedule, not months later.
Generic dev shop vs IRPR: the real difference
You get what you pay for. Here is what separates an expert custom application development firm from a generic agency.
Many firms operate like body shops: they staff whoever is available, charge hourly, and hand off projects frequently. IRPR builds dedicated teams of senior engineers who stay with your project from kickoff to launch.
We write clean, testable code with CI/CD pipelines, automated tests, and monitoring from day one. Every project includes a production deployment and knowledge transfer to your team.
- Junior developers with 1-2 years experience
- Hourly billing with no cap
- No compliance expertise
- Code without tests or documentation
- Handoffs between project managers
- Delays due to resource shuffling
- Senior engineers averaging 8 years experience
- Fixed price after 1-week Roadmap
- HIPAA, PCI-DSS, SOC 2 compliance built in
- Automated tests, CI/CD, and full docs in your repo
- One team from start to launch (and beyond)
- Guaranteed on-time delivery (98% track record)
How we build your custom application in 4 phases
Our process removes uncertainty. You know exactly what you get, when, and for how much.
We start with a 1-2 week Discovery phase where we understand your users, data, and compliance needs. Then we produce a fixed-price Roadmap with wireframes, tech stack decisions, and milestones.
After you approve the Roadmap, we build your app in 2-week sprints with weekly demos. You see real working software every Friday. We deploy to production after the final sprint with monitoring and documentation included.
What ships with every custom application we build
Every project includes these deliverables as standard. No hidden extras, no licensing fees, no black boxes.
We believe in transparency. Your team gets everything needed to maintain and extend the app after launch. No vendor lock-in.
- Full source code in your private GitHub repository
- CI/CD pipeline (GitHub Actions or GitLab CI)
- Automated unit tests and integration tests (80%+ coverage)
- Production deployment on AWS, GCP, or your own servers
- Sentry error tracking and Datadog performance monitoring
- API documentation (Swagger/OpenAPI)
- Admin dashboard with user management and audit logs
- One-hour knowledge transfer session with your dev team
- Post-launch support for 30 days (bug fixes, small adjustments)
