Hire an Expert REST API Development TeamREST API
We build secure, scalable REST APIs since 2014. Fixed price delivery in 8-12 weeks with full code ownership.
IRPR builds expert REST API development for startups and enterprises. We use Node.js, Python, Go, and .NET to design RESTful APIs with OpenAPI specs, JWT auth, and rate limiting.
We ship production-ready APIs with unit tests, CI/CD, and Postman collections in 8-12 weeks. Pricing starts at $80K and scales to $250K for complex multi-service systems. APIs are built to PCI-DSS, HIPAA, and SOC 2 standards.
Our clients are CTOs needing a dedicated API backend for their SaaS platform, product managers integrating third-party data via custom endpoints, and startup founders building a scalable MVP with public API access.
Types of software we ship.
Public REST API
Expose your product data through a well-documented public API. Includes API key management, rate limiting, and developer portal. Built with Express.js and Swagger.
Internal Microservices API
Decouple your monolithic app into RESTful microservices. Uses Docker, Kubernetes, and gRPC for service-to-service communication. Average latency reduction 40%.

Why You Need an Expert REST API Development Team
Poorly designed APIs cost time and money. IRPR builds APIs that scale from day one.
Common API problems include wrong endpoint design, missing error handling, and slow response times. These lead to integration delays and unhappy developers.
IRPR prevents these issues by using OpenAPI specs from day one, 100% automated testing, and performance benchmarks. Every endpoint hits sub-200ms response times.
Expert REST API Development vs. Generic Freelancers
Most freelancers deliver broken APIs. IRPR delivers production-ready systems.
Freelancers often skip documentation, testing, and security. You end up with an API that breaks in production and has no support.
IRPR builds APIs as a complete product, not a quick script. You get docs, tests, monitoring, and a team that stays until launch.
- No OpenAPI spec
- No automated tests
- No CI/CD pipeline
- No security audit
- No documentation portal
- No post-launch monitoring
- OpenAPI spec at day one
- 100% unit/integration tests
- CI/CD with GitHub Actions
- OWASP top 10 security review
- Developer portal with Postman
- Sentry and New Relic monitoring
Our Process for Building Expert REST APIs
We follow a proven 4-phase process to deliver your API on time and on budget.
Each phase has clear deliverables and milestones. You see progress every week and can adjust scope as needed.
The Roadmap phase locks the price and timeline. After that, we build and test in 2-week sprints until launch.
