Why choose IRPR for REST API development
We deliver APIs that scale from day one.
Every REST API we build starts with an OpenAPI spec. You see endpoints, data models, and authentication before a single line of code is written. This eliminates surprises and cuts feedback loops.
Our APIs are built by senior engineers with 8+ years of backend experience. We use stateless architecture, versioning, and rate limiting by default. All endpoints are documented with Swagger UI and tested with automated suites.
How we differ from generic API shops
Most development agencies deliver spaghetti code. We ship clean, documented, versioned APIs.
Generic firms often skip documentation or produce vague timeline estimates. They may not understand compliance requirements like HIPAA or PCI-DSS. Code quality varies because junior developers handle the work.
IRPR assigns senior engineers only. We produce OpenAPI docs, run integration tests, and set up CI/CD pipelines. Every project includes a compliance review, and you own all code and IP.

Our 4-phase build process for REST APIs
From idea to production in 8-12 weeks.
We use a structured 4-phase process to eliminate guesswork. Each phase ends with a deliverable you can review and approve.
You see progress every 2 weeks via demos. Changes are easy because we work from an OpenAPI spec updated with your feedback.
