Why IRPR is the best custom backend development agency
We have shipped over 200 backend systems for clients in 50+ countries.
Our engineers have built backends that handle 10 million requests per day with 99.9% uptime. We use Node.js, Go, Python, PostgreSQL, and AWS. Every project includes automated testing, monitoring with Datadog, and error tracking with Sentry.
We are the best custom backend development agency because we deliver on time and on budget. 98% of our projects ship within the original timeline. Our fixed pricing means no surprise invoices. You know the cost before we write a line of code.
The difference between IRPR and generic dev shops
Most backend agencies overpromise and underdeliver. We do the opposite.
Generic dev shops assign junior developers to your project and bill by the hour. They use outdated tech and ignore security best practices. You end up with a fragile backend that breaks under load.
IRPR assigns senior engineers with 10+ years of experience. We use modern tech like Node.js, Go, and AWS Lambda. Every project includes automated CI/CD, security scanning, and performance testing.
- Junior developers with 2 years experience
- Hourly billing with no cap
- No automated testing
- No CI/CD pipeline
- No monitoring or error tracking
- No security audit
- Senior engineers with 10+ years experience
- Fixed price with no surprises
- 100% test coverage
- GitHub Actions CI/CD
- Datadog monitoring and Sentry error tracking
- OWASP security audit before launch
How we build your custom backend in 8-12 weeks
Our process is designed to eliminate risk and ship fast.
We start with a 1-week Roadmap phase where we define the architecture, tech stack, and API contracts. You get a detailed project plan with a fixed price. No ambiguity.
Then we build in 2-week sprints. You see working code every 14 days. We deploy to staging on AWS and you can test the API live. At the end of 8-12 weeks, you have a production-ready backend.
What ships with every custom backend project
You get more than just code. You get a production-ready system.
Every project includes everything you need to run your backend in production. We do not hand off a half-finished prototype. You get a fully deployed system with monitoring, error tracking, and automated deployments.
Your team can take over immediately because we document everything and hand over full source code ownership. No licensing fees, no vendor lock-in.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Dockerized microservices with docker-compose
- Automated test suite (unit, integration, e2e)
- API documentation in Swagger/OpenAPI
- Database schema and migration scripts
- Sentry error tracking
- Datadog monitoring dashboard
- AWS infrastructure as code (Terraform or CDK)
- Security audit report (OWASP top 10)
