Why choose an expert backend app development company
Your backend is the foundation of every feature your users see.
A poorly designed backend causes slow load times, data loss, and security breaches. IRPR builds backend systems that scale from 100 to 10 million users without rewrites. We use Node.js, PostgreSQL, and Redis for high throughput and low latency.
Our team of senior engineers has shipped 200+ backend apps across 50 countries. Every project includes automated testing, CI/CD pipelines, and 99.9% uptime SLAs. We write code that passes HIPAA, PCI-DSS, and SOC 2 audits.
How IRPR differs from other backend development agencies
Most agencies bill hourly and change scope. We do the opposite.
Generic dev shops start coding without a clear plan. They use junior developers, skip testing, and deliver late. You pay for their learning curve and get code you cannot maintain.
IRPR starts with a Roadmap phase (week 2) that defines every endpoint, schema, and integration. We give you a fixed price before any code is written. Senior engineers only. Source code ownership. No surprises.
- Hourly billing with no cap
- Junior developers learning on your project
- No architecture document
- No automated tests
- No CI/CD pipeline
- You do not own the code
- Fixed price from $80K
- Senior engineers with 10+ years experience
- Roadmap phase with full architecture
- 100% test coverage on critical paths
- CI/CD on GitHub Actions or GitLab
- Full source code ownership
Our backend development process
We follow a 4-phase process that eliminates guesswork.
Every project starts with an Idea phase where we map your requirements to a technical specification. Then we build a Roadmap with wireframes, data models, and API contracts. The Product phase is where we write code in 2-week sprints. Finally, Release deploys to production with monitoring and documentation.
This process has delivered 200+ backend apps on time and on budget. You see progress every sprint. No black boxes, no last-minute surprises.
What ships with every backend project
You get more than code. You get a production-ready system.
Every backend project includes infrastructure as code, automated deployments, and monitoring dashboards. We set up Sentry for error tracking, Datadog for performance, and PagerDuty for alerts. Your team can start contributing on day one.
We also provide Postman collections, Swagger docs, and a runbook for common operations. No tribal knowledge. Everything is documented.
- Source code in your GitHub or GitLab repo
- CI/CD pipeline with automated tests
- Infrastructure as code (Terraform or Pulumi)
- Sentry error tracking
- Datadog performance monitoring
- Swagger/OpenAPI documentation
- Postman collection for all endpoints
- Runbook for deployment and rollback
- 99.9% uptime SLA
- Full ownership of all code and IP
