Senior Full Stack App Development by the Numbers
IRPR's track record shows consistent delivery across 200+ products.
Every project we ship goes through the same rigorous process. Our senior engineers average 10 years of experience, and we maintain a 98% on-time delivery rate.
We have served clients in 50+ countries across every major industry. Our fixed-price model means you never pay for scope creep.
Generic Dev Shop vs Senior Team
Not all development teams deliver the same quality.
Many agencies staff junior developers and bill hourly, leading to unclear timelines and unexpected costs.
IRPR only assigns senior engineers, provides a fixed price after week 2, and gives you full code ownership from day one.
- Junior-heavy team mix
- Hourly billing with scope creep
- No dedicated project manager
- Unclear code ownership
- Slow response to bugs
- Generic tech stack without optimization
- Senior engineers only (10+ years avg)
- Fixed price from week 2 Roadmap
- Dedicated PM plus weekly demos
- Full code ownership in your repo
- Sentry monitoring and 4hr SLA
- Stack chosen for your specific needs
Our Full Stack Development Process
We follow a proven 4-phase process from idea to release.
Every engagement starts with a free discovery call to understand your concept and goals.
Our process ensures you see progress weekly and get a fixed price before any development begins.
What Ships with Your Full Stack App
Every project includes these deliverables by default.
We don't cut corners. Source code, infrastructure, and documentation are all included in the fixed price.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Cloud infrastructure on AWS (or your choice)
- Sentry error tracking and monitoring
- PostgreSQL database with migrations
- Stripe integration for payments
- Authentication (JWT or OAuth)
- Admin dashboard for data management
- Unit tests with Jest
- API documentation (Swagger/OpenAPI)
