Why IRPR is a Top Backend App Development Company
We deliver backend systems that handle millions of requests with 99.9% uptime.
Our team has shipped over 200 backend applications for clients in 50+ countries. We use Node.js, Python, Go, and Rust depending on the performance and scalability needs. Every API is documented with OpenAPI and tested with Postman and Jest.
We follow a strict 4-phase process: Idea, Roadmap, Product, Release. The Roadmap phase (week 2) produces a fixed-price quote with a detailed technical design. No surprises. No scope creep.
Generic Dev Shop vs IRPR
Not all backend development companies deliver the same quality.
Many agencies promise backend expertise but deliver spaghetti code with no tests. They bill by the hour, extend timelines, and hand over code that breaks in production.
IRPR is different. We write code that is tested, documented, and deployed with CI/CD. Our fixed-price model means you know the cost upfront.
- hourly billing with no cap
- no automated tests
- no CI/CD pipeline
- no API documentation
- single developer with no oversight
- handoff without deployment support
- fixed price from Roadmap phase
- 90%+ test coverage (Jest, Pytest)
- CI/CD on GitHub Actions or GitLab
- OpenAPI 3.0 spec for every API
- senior engineers + tech lead review
- deployment to AWS/GCP/Azure included
Our Backend Development Process
From idea to production in 8-12 weeks with clear milestones.
We start with a 2-week Roadmap phase where we define the architecture, data model, API design, and infrastructure. You get a fixed-price proposal and a detailed timeline.
Then we build in 2-week sprints. You see working software every sprint. We deploy to staging after sprint 2 and production after sprint 6.
What Ships with Every Backend Project
Every backend we build comes with these deliverables by default.
No hidden fees. No missing documentation. Everything listed here is included in the fixed price.
- Source code in your private GitHub/GitLab repo
- CI/CD pipeline with automated tests and deployment
- OpenAPI 3.0 or GraphQL schema documentation
- Unit and integration tests (90%+ coverage)
- Dockerized development environment
- Infrastructure as code (Terraform or Pulumi)
- Monitoring and alerting (Datadog, Sentry, PagerDuty)
- Post-deployment support for 30 days
- Admin panel or API playground (Swagger UI or GraphiQL)
- Security audit (OWASP top 10, dependency scanning)
