Why IRPR is the best backend web development agency
We ship production-grade backend systems on time and on budget.
IRPR has shipped over 200 products across 50 countries since 2018. Every backend project uses a fixed price model. You know the cost before we write a single line of code. Our average MVP delivery is 12 weeks.
Our senior engineers average 10+ years of experience. We use Node.js, Python, Go, and PostgreSQL. Every project includes CI/CD pipelines, automated testing, and infrastructure as code. You get full source code ownership.
Generic dev shop vs the best backend agency
Most agencies bill hourly and miss deadlines. IRPR delivers fixed-price backend systems on time.
Generic dev shops often assign junior developers to your project. They use hourly billing that leads to scope creep and surprise invoices. They skip automated testing and leave you with unmaintainable code.
IRPR assigns senior engineers only. We use a fixed price model agreed in week 2. Every project includes automated testing, CI/CD, and infrastructure as code. You own everything.
- hourly billing with no cap
- junior or mid-level engineers
- no automated testing
- no CI/CD pipeline
- code owned by agency
- missed deadlines
- fixed price agreed in week 2
- senior engineers only (10+ years avg)
- automated tests with 90%+ coverage
- CI/CD on GitHub Actions
- full source code ownership
- 98% on-time delivery
