Why choose an expert backend API development firm?
Here are the numbers that matter.
We have shipped 200+ products across 50 countries. Our APIs power applications handling millions of requests per day.
Our average project timeline is 12 weeks from kickoff to deployment. 98% of our projects deliver on time and on budget.
Generic dev shop vs expert backend API firm
Not all API development is equal. Here's what sets IRPR apart.
Generic shops treat APIs as an afterthought. They use boilerplate code, skip documentation, and ignore security best practices.
IRPR builds APIs that are production-ready from day one. Every endpoint is documented, tested, and monitored.
- No API documentation
- Inconsistent error handling
- No rate limiting
- No monitoring or alerting
- Manual deployment
- No load testing
- OpenAPI or GraphQL schema docs
- Standardized error responses
- Rate limiting with Redis
- Sentry + Datadog monitoring
- CI/CD with GitHub Actions
- k6 load testing before launch

- OpenAPI 3.0 or GraphQL schema documentation
- Postman collection with example requests
- CI/CD pipeline with GitHub Actions
- Docker containers for local development
- API monitoring with Sentry and Datadog

Senior engineers only
Our team consists of engineers with 10+ years of experience. No junior developers, no outsourcing. Every API is built by someone who has shipped production systems at scale.
Production-ready from day one
We don't deliver prototypes. Every API includes authentication, rate limiting, logging, monitoring, and error handling. You can deploy to production immediately after handoff.
Full code ownership
You own all source code, documentation, and deployment scripts. There are no licensing fees or lock-in. We transfer everything to your GitHub or GitLab repository.
Compliance built in
We build APIs that meet SOC 2, HIPAA, PCI-DSS, and GDPR requirements. Our engineers implement encryption, audit logs, and access controls as standard practice.

Every project includes 30 days of post-launch support. We fix bugs, answer questions, and provide performance tuning. Extended maintenance plans are available.
