Leading REST API Development Services for Scalable SystemsREST API Development
We build secure, high-performance REST APIs that teams rely on. Over 200 APIs shipped across 50+ countries.
IRPR builds production-grade REST APIs using Node.js, Python (FastAPI), Go, and Rust. Our APIs are designed for high throughput, low latency, and easy integration by third-party developers.
We ship a fully documented API with test coverage, rate limiting, and CI/CD pipeline in 8-12 weeks. Pricing ranges from $80K to $250K depending on complexity. All data is encrypted in transit and at rest (AES-256).
Who hires us: SaaS founders who need a scalable backend, enterprise engineering teams modernizing legacy systems, healthcare startups requiring HIPAA-compliant APIs, and fintech firms needing PCI-DSS certified endpoints.

Why Top Companies Choose IRPR for REST API Development
Every project is built on a proven framework with real metrics.
IRPR has shipped over 200 REST APIs across fintech, healthcare, and SaaS. Our average time from kickoff to production is 12 weeks.
We maintain 99.9% uptime on production APIs and a 98% on-time delivery record. Every API includes automated testing and monitoring.
The Difference Between a Generic Developer and IRPR
Not every team delivers a production-ready API with documentation and support.
Many dev shops hand you messy Express endpoints with no versioning. You spend months refactoring and adding auth.
IRPR delivers a versioned, documented REST API with CI/CD, rate limiting, and 24/7 infrastructure support from day one.
- No API versioning
- Minimal test coverage
- No rate limiting
- No documentation
- No deployment scripts
- No post-launch support
- Semantic versioning (v1, v2)
- 90%+ test coverage (Jest, Mocha)
- Redis-based rate limiting
- OpenAPI/Swagger docs auto-generated
- Docker + Kubernetes deployment
- Ongoing support and monitoring
How We Build Your REST API: 4 Phases
From plan to production in 8-12 weeks.
Phase 1: Architecture design. We choose the language and framework (FastAPI, Express, Gin, Actix).
Phase 2: Core endpoints. We build CRUD, authentication, and integration points with Stripe, HubSpot, or your legacy systems.
What Ships with Every REST API from IRPR
No surprises. Every deliverable is listed in your contract.
When your API is ready, you receive all of the following, fully deployed and documented.
- Source code in your private GitHub repo
- OpenAPI/Swagger documentation
- Postman collection with example requests
- CI/CD pipeline using GitHub Actions
- Docker Compose setup for local development
- Unit and integration tests (Jest, Pytest)
- Rate limiting with Redis
- Authentication (JWT or OAuth2)
- API monitoring dashboard (Datadog)
- Deployment runbook and infrastructure as code (Terraform)
