The IRPR Difference vs. Generic Dev Shops
Most agencies promise fast APIs but deliver spaghetti code. IRPR delivers clean, documented, production-ready APIs on a fixed schedule.
We start with a two-week Roadmap phase where we define every endpoint, data model, and integration point. You get a fixed price and a 12-week timeline before we write a single line of code.
Our senior engineers use code reviews, automated tests, and staging environments. Every API ships with a Postman collection, Swagger UI, and a deployment runbook.
- Hourly billing with no cap
- No API documentation until the end
- Junior developers learning on your project
- No automated tests
- Deployment is your problem
- No SLA for uptime
- Fixed price from week 2
- OpenAPI 3.0 spec delivered in Roadmap phase
- Senior engineers with 10+ years experience
- 80%+ test coverage with Jest and Supertest
- CI/CD pipeline with GitHub Actions
- 99.9% uptime SLA on AWS or Azure
Our REST API Development Process
We follow a four-phase process that turns your idea into a production-ready REST API in 12 weeks.
Phase 1 is the Roadmap: we define every endpoint, data model, and integration. You get a fixed price and a detailed specification. Phase 2 is Build: we write code in two-week sprints with daily standups and weekly demos.
Phase 3 is Release: we deploy to staging, run load tests, and fix any issues. Phase 4 is Handoff: you get full source code, documentation, and a deployment runbook. We also provide 30 days of post-launch support.
What Ships with Every REST API
Every REST API project includes these 8 deliverables by default. No hidden fees, no surprises.
We believe in shipping a complete product, not just code. Every API includes documentation, tests, monitoring, and a deployment pipeline. You can take the code and run it yourself from day one.
- Source code in your private GitHub repository
- OpenAPI 3.0 specification (Swagger UI)
- Postman collection with example requests
- CI/CD pipeline with GitHub Actions
- Automated tests with 80%+ coverage (Jest, Supertest)
- Sentry error tracking and Datadog monitoring
- Deployment runbook for AWS ECS or Azure Kubernetes
- 30 days of post-launch support
