Why Choose a Leading Backend API Development Vendor
Your API is the foundation of your product. A poorly built API costs time, money, and customers.
IRPR has shipped over 200 backend APIs for clients in 50 countries. Our APIs handle 10,000+ requests per second with 99.9% uptime. We use automated load testing with k6 and Artillery to guarantee performance before launch.
Every API we build includes OpenAPI documentation, Postman collections, and integration tests. Your team can start using the API on day one. We also provide a 30-day post-launch support window to handle any edge cases.
The Difference Between IRPR and Other Vendors
Most backend API vendors charge by the hour and deliver late. IRPR works differently.
IRPR gives you a fixed price after a 2-week Roadmap phase. You know the exact cost and timeline before we write a line of code. We use senior engineers only, with an average of 10+ years of experience.
Our process includes code reviews, automated testing, and weekly demos. You see working software every 7 days. No black box, no surprises.
- Hourly billing with no cap
- Junior developers with little oversight
- No API documentation included
- Delays from scope creep
- No post-launch support
- Code owned by the vendor
- Fixed price after Roadmap phase
- Senior engineers only (10+ years avg)
- OpenAPI docs and Postman collections included
- 8-12 week delivery with weekly demos
- 30-day post-launch support
- Full source code ownership
How IRPR Delivers Your Backend API
Our 4-phase process takes you from idea to production in 8-12 weeks.
Phase 1: Idea. We map your requirements, user flows, and data model in 3-5 days. You get a detailed specification document.
Phase 2: Roadmap. We design the system architecture, choose the tech stack, and give you a fixed price and timeline. This takes 1-2 weeks.
What Ships with Every Backend API
Every project includes these deliverables by default. No hidden costs.
IRPR treats your API as a product, not a project. That means we ship everything your team needs to maintain and scale it independently. You get full documentation, automated tests, and a production-ready deployment.
Our standard package includes source code, CI/CD pipeline, API documentation, and monitoring setup. You can deploy to any cloud provider or your own servers.
- Source code in your private GitHub or GitLab repo
- CI/CD pipeline on GitHub Actions or GitLab CI
- OpenAPI 3.0 documentation with Swagger UI
- Postman collection with example requests
- Automated unit and integration tests (80%+ coverage)
- Docker containers for local development
- Sentry error tracking and Datadog monitoring
- Load test results from k6 or Artillery
- One-click deploy to AWS, GCP, or Azure
- 30-day post-launch support via Slack
