Why partner with IRPR for custom application development?
We have shipped over 200 custom applications for clients in 50+ countries.
Every project is built by senior engineers with 8+ years of experience. We do not use junior developers or outsource work.
Our fixed-price model means you know the exact cost before development begins. No hourly billing, no budget surprises.
The real difference between a generic dev shop and IRPR
Most agencies charge by the hour and over-promise on delivery dates.
With IRPR, you work directly with senior engineers who understand your business requirements and compliance needs.
Our process is transparent: weekly demos, a shared roadmap, and a fixed price that covers everything.
- Hourly billing with no cap
- Junior developers on your project
- No compliance expertise
- Fixed scope that misses requirements
- No ownership of code
- No support after launch
- Fixed price from the Roadmap phase
- Senior engineers only (8+ years)
- HIPAA/SOC 2/PCI DSS compliant
- Agile process with weekly demos
- Full source code ownership
- 6 months of post-launch support
Our 4-phase approach to custom application development
From idea to release in 12 weeks with no surprises.
Each phase has a clear deliverable and a fixed price. You approve the next phase before we proceed.
This structure reduces risk and keeps the timeline predictable.
What ships with your custom application
Everything you need to run and maintain your application independently.
We do not hand over a zip file and walk away. You get the full engineering stack.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions or GitLab CI
- Docker containers for any environment
- Sentry error tracking and performance monitoring
- Post-deployment monitoring (PagerDuty, Datadog)
- API documentation (OpenAPI/Swagger)
- Admin dashboard for key metrics
- User authentication with Auth0 or custom JWT
- Database backups and recovery plan
- 6 months of bug fixes and support
