Why you need a professional custom backend development agency
Your backend is the foundation of your product. A poorly built one costs time, money, and users.
IRPR has shipped 200+ backend systems across 50+ countries. Our average project timeline is 12 weeks, and 98% of projects deliver on schedule. We use Node.js, Python, and Go for speed and reliability.
Every backend we build includes automated testing, CI/CD pipelines, and monitoring with Sentry and Datadog. You get full code ownership and a 99.9% uptime SLA.
How IRPR is different from other backend development agencies
Most agencies bill hourly and change scope mid-project. We do the opposite.
Generic dev shops often assign junior developers and bill by the hour. Scope creep is common, and code quality suffers. You end up paying more for a system that needs rewrites.
IRPR assigns senior engineers only. We give you a fixed price after the Roadmap phase (week 2). No hourly billing, no surprise invoices. You own the code from day one.
- Hourly billing with no cap
- Junior developers on your project
- No fixed scope or timeline
- Minimal documentation
- No compliance expertise
- Code ownership unclear
- Fixed price from $80K
- Senior engineers only (8+ years)
- Clear roadmap and timeline
- Comprehensive API docs and tests
- HIPAA, PCI, SOC 2 ready
- Full code ownership from day one
Our process for custom backend development
We follow a four-phase process that eliminates surprises and delivers on time.
Every backend project starts with a 2-week Discovery phase where we map your requirements, data flow, and integrations. Then we build a detailed Roadmap with a fixed price and timeline.
The Build phase runs in 2-week sprints with live demos. After launch, we provide 30 days of support and hand over all code, docs, and infrastructure.
What ships with every backend project
You get more than code. Every delivery includes the tools and docs you need to run your system.
We believe in full transparency. All source code is in your GitHub repository from the first commit. Infrastructure is defined as code with Terraform or Pulumi.
Monitoring, error tracking, and logging are set up before launch. You get a runbook and architecture documentation written for your team.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions or CircleCI
- Infrastructure as code (Terraform or Pulumi)
- API documentation (Swagger/OpenAPI or GraphQL schema)
- Unit and integration tests (coverage > 80%)
- Sentry error tracking and Datadog monitoring
- Deployment runbook and architecture diagram
- Post-launch support for 30 days
- HIPAA/PCI compliance documentation if required
- Admin dashboard for monitoring system health
What we ship in this practice.
