Why Hire a Senior Backend App Development Firm
Most backend projects fail because the team lacks senior experience. IRPR fixes that.
We only hire engineers with 10+ years of production experience. Every backend we build uses PostgreSQL, Redis, and Docker from day one. We don't hand off work to juniors. The engineer who designs your architecture also writes the code.
Our fixed price model means you know the cost before we write a line of code. In the Roadmap phase (week 2), we spec the entire backend and give you a firm quote. No hourly billing, no scope creep, no surprise invoices.
How IRPR Differs from Other Backend Development Firms
Generic dev shops sell you junior hours. We sell senior outcomes.
Most backend agencies staff projects with junior developers who learn on your dime. They charge hourly and the timeline stretches. You end up with a backend that barely scales and a bill that doubled.
IRPR assigns a senior engineer from day one. We build your backend in 8-12 weeks at a fixed price. The code is yours, fully documented, and deployed with CI/CD on GitHub Actions. No handoffs, no surprises.
- Juniors write most of the code
- Hourly billing with no cap
- No compliance knowledge
- Timeline slips by 2-3x
- No CI/CD pipeline
- You don't own the code
- Senior engineers with 10+ years
- Fixed price from the Roadmap phase
- Built for HIPAA, PCI-DSS, SOC 2
- 8-12 week delivery
- CI/CD on GitHub Actions
- Full code ownership
Our Process for Building Your Backend App
We follow a clear 4-phase process that removes guesswork.
Phase 1 is the Idea phase where we map your requirements to a technical spec. Phase 2 is the Roadmap phase where we produce a detailed plan and a fixed price. Phase 3 is the Product phase where we build and test. Phase 4 is the Release phase where we deploy and hand over.
Each phase has clear deliverables and a go/no-go decision point. You never pay for work you don't approve. The average timeline from kickoff to production is 12 weeks for a full backend.
What Ships with Every Backend App
Every backend we build includes these deliverables by default.
You get a production-ready backend with CI/CD, monitoring, and documentation. No extra charges for the things that matter. We include everything your team needs to operate the system day one.
All code is in your GitHub repository from the first commit. We use GitHub Actions for automated testing and deployment. You own the entire codebase with no licensing restrictions.
