Why professional backend app development consultants matter
Numbers don't lie. Here's what we deliver.
Our team has shipped over 200 backend systems across 50 countries. Every project is built by senior engineers with 10+ years of experience.
We deliver on time 98% of the time. Our average project runs 12 weeks from kickoff to production.
Generic dev shop vs IRPR
Not all backend consultants are the same. See the difference.
Most dev shops assign junior developers and charge by the hour. They change scope and surprise you with bills.
IRPR assigns senior engineers only, gives a fixed price, and delivers in 12 weeks. No surprises.
- Junior developers
- Hourly billing
- Scope creep
- No compliance expertise
- No post-launch support
- Black box process
- Senior engineers only
- Fixed price from day one
- Clear scope in Roadmap phase
- HIPAA, PCI, SOC 2 certified
- 12-week delivery guarantee
- Full transparency with daily standups
Our backend development process
We follow a proven 4-phase process.
Phase 1: Idea - we review your concept and define technical requirements. Phase 2: Roadmap - we create a detailed plan with wireframes, architecture, and fixed quote.
Phase 3: Product - we build the backend in sprints with weekly demos. Phase 4: Release - we deploy to production and provide 30 days of warranty support.
