Why choose a senior custom application development company
Senior engineers ship faster and with fewer bugs.
Junior developers cost less per hour but take 3x longer and produce 5x more bugs. A senior engineer at IRPR has 10+ years building production apps. They know React, Node.js, Python, AWS, and Postgres without looking up syntax.
We assign only senior engineers to every project. No juniors. No offshore teams. This is why our average MVP ships in 10 weeks and our on-time rate is 98%. You get a working product, not a learning exercise.
How IRPR differs from other development companies
We don't bid on projects we can't deliver.
Most agencies promise anything to win the deal. They assign junior developers, bill by the hour, and the project runs 6 months over schedule. You end up with a half-finished app and a burned budget.
IRPR gives you a fixed price after the Roadmap phase. You know the exact cost before we write code. We assign senior engineers only. We ship in 8-12 weeks or we tell you why before you start.
- assigns junior developers to save costs
- bills hourly with no cap
- changes scope without changing price
- takes 6-12 months for an MVP
- no compliance expertise
- code ownership is unclear
- assigns senior engineers only (10+ years)
- fixed price after Roadmap phase
- scope changes are documented and priced
- ships MVP in 8-12 weeks
- HIPAA, PCI-DSS, SOC 2 compliant by default
- you own 100% of the code
Our process for building your custom application
From idea to production in 4 phases.
Phase 1 is the Idea phase where we clarify your requirements and define success metrics. Phase 2 is the Roadmap phase where we create a detailed plan with wireframes, tech stack, and a fixed price.
Phase 3 is the Product phase where we build your application in 2-week sprints. You see progress every 14 days. Phase 4 is the Release phase where we deploy to production, set up monitoring, and hand over the code.
What ships with every custom application
Every project includes these deliverables by default.
You get more than code. You get a production-ready system with monitoring, security, and documentation. No hidden costs for deployment or setup.
Our checklist ensures your team can take over immediately after launch. Every tool and account is set up and documented.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Sentry error tracking and performance monitoring
- AWS or GCP infrastructure with Terraform
- Stripe or Plaid payment integration
- PostgreSQL database with migrations
- Admin dashboard for managing users and data
- API documentation (Swagger/OpenAPI)
- Unit and integration tests (80%+ coverage)
- Deployment runbook and architecture diagram
