Why hire an expert custom backend development firm
A strong backend is the foundation of any reliable digital product. Here is what IRPR delivers.
Every backend we build starts with a 2-week Roadmap phase. We map out your data model, API endpoints, and infrastructure. You get a fixed price and a 12-week timeline before any code is written.
We use the same tools that power Netflix and Uber: Node.js, Python, Go, PostgreSQL, Redis, Docker, and Kubernetes. Our backends handle millions of requests per day with 99.9% uptime.
Generic dev shop vs. an expert custom backend development firm
Not all backend teams work the same way. Here is the difference.
Many agencies treat backend as a side task. They reuse old code, skip documentation, and deliver a black box. IRPR treats your backend as the core asset it is.
We write clean, tested, documented code. Every API has endpoint tests, every service has monitoring dashboards. You own the complete codebase, not a tangle of dependencies.
- Hourly billing – no price certainty
- No dedicated backend architect
- Copy-paste code from past projects
- Minimal tests and documentation
- Deployment manual – no CI/CD
- No compliance or security review
- Fixed price from week 2 of Roadmap
- Senior backend engineer assigned
- Custom architecture for your needs
- 85%+ test coverage, full Swagger docs
- CI/CD on GitHub Actions, auto-deploy
- HIPAA/PCI/SOC 2 built in from day 1
Our process: from idea to production backend
We follow a proven 4-phase method that eliminates guesswork.
Every project starts with a 2-week Roadmap where we define your data schema, API contract, and infrastructure. You get a fixed price and timeline before we write a single line of production code.
After the Roadmap, we build in 2-week sprints. You see a working backend every sprint. We deploy to staging and run load tests. No surprises at the end.
What ships with every custom backend
Everything you need to run and maintain your backend in production.
We don't just hand over code. We deliver a complete system including deployment pipelines, monitoring, and documentation. Your team can start adding features the same day we deploy.
You own all code and configuration. No lock-in. No hidden fees. You can run the backend yourself or keep IRPR on retainer for updates.
- Source code in your private GitHub repo
- CI/CD pipeline using GitHub Actions
- Dockerized services for local and production
- PostgreSQL or MongoDB database with migrations
- REST or GraphQL API with Swagger/OpenAPI docs
- Sentry error tracking and uptime monitoring
- Infrastructure-as-code with Terraform on AWS/GCP
- Load testing report (up to 10K concurrent users)
- Security audit report (OWASP Top 10)
- 30-day post-launch support and knowledge transfer
