Why hire a senior full stack software development firm
A senior team ships faster, writes cleaner code, and avoids costly rewrites.
IRPR has shipped over 200 products across 50+ countries. Every project is built by engineers with 10+ years of experience. We do not use junior developers or outsource work. This means your project is done right the first time.
Our average MVP timeline is 12 weeks. We use a structured process: Idea (week 1), Roadmap (week 2), Product (weeks 3-10), Release (weeks 11-12). Each phase has clear deliverables and a fixed price.
Generic dev shop vs a senior full stack software development firm
Not all agencies are the same. Here is what separates IRPR from a generic dev shop.
Generic dev shops often assign junior developers to your project. They bill by the hour, change scope without notice, and deliver code that needs to be rewritten.
IRPR assigns senior engineers only. We give you a fixed price, a clear roadmap, and production-ready code that your team can maintain.
- Junior or mid-level developers
- Hourly billing with no cap
- No compliance expertise
- Code without tests
- Unclear timeline
- No post-launch support
- Senior engineers with 10+ years
- Fixed price per phase
- HIPAA, PCI-DSS, SOC 2 ready
- Automated tests and CI/CD
- 8-12 week delivery
- 30-day post-launch warranty
How our senior full stack development process works
Four phases from idea to release. No surprises.
Every project starts with a two-day Idea phase where we map out your core requirements and user flows. You pay a fixed fee of $5K for this phase.
After the Idea phase, we create a detailed Roadmap with wireframes, tech stack, timeline, and a fixed price. If you approve, we start building. If not, you walk away with the Roadmap.
What ships with your senior full stack project
Every project includes these deliverables by default.
When you hire IRPR as your senior full stack software development firm, you get more than just code. You get a complete, production-ready system.
All source code is yours. We never claim ownership. You can take it to any internal team or other agency.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Automated unit and integration tests
- Deployed to AWS, Azure, or GCP
- Sentry error tracking
- Datadog performance monitoring
- Admin dashboard for managing users/data
- API documentation (Swagger/OpenAPI)
- 30-day post-launch support
- Full ownership of all code and IP

Why teams hire us.
Senior engineers only
Every developer on your project has 10+ years of experience. No junior or mid-level engineers. Our team has shipped code at Google, Amazon, and Microsoft.
Fixed price, not hourly
You get a fixed quote during the Roadmap phase. No hourly billing, no surprise invoices, no scope creep. If we add features, we quote separately.
8-12 week delivery
We ship MVPs in 8-12 weeks. Our process is designed for speed: two-day Idea phase, one-week Roadmap, then eight weeks of building.
Compliance built in
We handle HIPAA, PCI-DSS, SOC 2, and FERPA as part of the build. No separate compliance audit needed after launch.
Full code ownership
You own all source code, IP, and design assets. We never license or retain rights. You can take the code anywhere.
30-day post-launch warranty
After launch, we fix any bugs and provide support for 30 days. We also set up monitoring so you can see issues before users do.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
