Why IRPR Is an Experienced Backend App Development Agency
We have shipped 200+ backend systems across 50+ countries with a 98% on-time delivery rate.
IRPR has been building backend systems since 2016. Our senior engineers average 10+ years of experience each. We have delivered backends for healthcare platforms handling PHI, fintech apps processing millions in transactions, and ecommerce systems managing inventory across 20 warehouses.
Every backend we build starts with a Roadmap phase (week 2) where we define the architecture, data model, and API contracts. You get a fixed price and timeline before any code is written. No surprises.
How IRPR Differs From Other Backend Development Agencies
Most agencies bill hourly and change scope. IRPR gives you a fixed price and a clear timeline.
Generic dev shops often start coding without a clear architecture. They use hourly billing, which means you pay for their learning curve. They deliver late and over budget.
IRPR does the opposite. We spend week 2 creating a detailed Roadmap with architecture diagrams, API specs, and a fixed quote. You approve it before we write a single line of code. We deliver on time and on budget.
- Hourly billing with no cap
- Starts coding without architecture plan
- Junior developers on your project
- No compliance expertise
- Delivers 3-6 months late
- Code ownership is unclear
- Fixed price from Roadmap phase
- Architecture and API contracts before coding
- Senior engineers with 10+ years average
- HIPAA, PCI-DSS, SOC 2 built in
- 8-12 week delivery, 98% on time
- Full source code ownership
Our Backend Development Process: From Idea to Production
We follow a four-phase process that guarantees clarity and speed.
Every project at IRPR goes through Idea, Roadmap, Product, and Release phases. This structure ensures we build the right thing, the right way, and ship it on time.
The Roadmap phase is unique. In week 2, we deliver a detailed document with architecture diagrams, API specs, data models, and a fixed price. You approve it before we build anything.
