Why Choose a Leading Backend API Development Agency
IRPR has shipped 200+ APIs for clients in 50 countries. Our APIs handle millions of requests per day.
We use Node.js, Python, Go, and TypeScript. Each API is designed for scalability, security, and maintainability. We write unit tests, integration tests, and API documentation with Swagger.
Our APIs run on AWS, GCP, or Azure. We set up CI/CD pipelines with GitHub Actions. Monitoring with Datadog and Sentry keeps uptime at 99.9%.
The Difference Between Generic Shops and IRPR
Most dev shops sell hours. IRPR sells outcomes with fixed pricing and senior engineers.
We don't assign junior developers to your project. Every engineer has 8+ years of experience. Our Roadmap phase gives you a fixed price and timeline before any code is written.
You own the code, the IP, and the infrastructure. We ship source code to your repo, CI/CD pipelines, and monitoring dashboards. No black boxes.
- Hourly billing with no cap
- Junior developers on your project
- No clear timeline
- Code stays on their servers
- No monitoring setup
- Scope creep without change orders
- Fixed price from week 2
- Senior engineers only (8+ years)
- 12-week delivery guarantee
- Code in your repo day one
- Sentry + Datadog monitoring included
- Scope locked in Roadmap phase
Our Backend API Development Process
We follow a 4-phase process: Idea, Roadmap, Product, Release. Each phase has clear deliverables.
Phase 1: Idea. We discuss your requirements, target users, and business goals. This takes 1 week. You pay nothing upfront.
Phase 2: Roadmap. We create a detailed spec with wireframes, data models, and API endpoints. You get a fixed price and timeline. This costs $5K and is deducted from the build.
What Ships With Every Backend API
Every API project includes these deliverables by default.
You get a production-ready API with documentation, monitoring, and CI/CD. No hidden costs.
- Source code in your GitHub or GitLab repo
- CI/CD pipeline with GitHub Actions
- API documentation via Swagger or Postman
- Unit and integration tests (80%+ coverage)
- Docker containers for local development
- Sentry error tracking
- Datadog or CloudWatch monitoring
- Rate limiting and authentication (JWT or OAuth)
- Database schema with migrations
- Post-launch support for 30 days
