Expert Backend API Development PartnerAPI Development
We build production-grade APIs that handle millions of requests. Senior engineers start coding in week 1, not month 3.
IRPR is an expert backend API development partner for companies that need reliable, scalable APIs. We use Node.js, Python, Go, and Java to build REST and GraphQL APIs that handle millions of requests per day. Every API ships with automated testing, monitoring, and documentation.
We deliver production-ready backend APIs in 8-12 weeks with fixed pricing from $80K to $250K. Our APIs are built for HIPAA, PCI-DSS, SOC 2, and FERPA compliance. Each project includes CI/CD pipelines, error tracking, and a dedicated project manager.
Startups hire us to ship their first API before raising a seed round. Series A/B companies hire us to replace slow or broken internal APIs. Enterprise teams hire us to build microservices for healthcare and fintech systems. Founders who need a backend they can trust hire IRPR.

Why You Need an Expert Backend API Development Partner
A poorly designed API costs more in rework than building it right the first time.
IRPR has shipped 200+ backend APIs for clients across 50 countries. We know the patterns that scale and the shortcuts that break. Every API we build includes automated tests, monitoring, and a documentation portal.
Our senior engineers have built APIs for PCI-DSS compliant fintech platforms and HIPAA compliant healthcare systems. We use the right tools for each job. Node.js for high-throughput APIs. Python for data-heavy endpoints. Go for low-latency microservices.
How We Differ from Generic Dev Shops
Most agencies promise APIs but deliver half-baked endpoints that need a rewrite.
IRPR starts every backend API project with a Roadmap phase. In week 2, you get a fixed quote, a detailed tech stack, and a delivery timeline. No ambiguous estimates. No scope creep.
We use CI/CD pipelines with GitHub Actions, Sentry for error tracking, and PagerDuty for alerts. Every API is covered by unit tests, integration tests, and load tests. We do not hand over code that has not been tested in production-like conditions.
- Hourly billing with unclear scope
- No dedicated project manager
- APIs with <10% test coverage
- No CI/CD pipeline
- No load testing
- Code ownership disputes
- Fixed price after Roadmap phase
- Dedicated PM with weekly updates
- 90%+ test coverage required
- CI/CD with GitHub Actions
- Load tests for 10x target traffic
- Full code ownership from day 1
Our Backend API Development Process
We deliver production APIs in 8-12 weeks using a proven four-phase process.
Phase 1 is the Roadmap where we define API endpoints, data models, and auth flows. This takes 1-2 weeks and produces a fixed quote. Phase 2 is development where our senior engineers build the API with continuous integration.
Phase 3 is testing, including load testing and security scanning. Phase 4 is release where we deploy to production and set up monitoring. You own the source code, the CI/CD pipeline, and all documentation.
What Ships with Every API
Our backend APIs are not just endpoints. They are production-ready systems.
Every IRPR-built API includes a full delivery package. You get source code in your GitHub repo, a CI/CD pipeline, API documentation in Swagger, and monitoring dashboards. No extra fees for deployment or testing.
- Source code in your private GitHub repo
- CI/CD pipeline using GitHub Actions
- Swagger / OpenAPI documentation
- Unit tests (90%+ coverage)
- Integration tests for all endpoints
- Load test scripts (k6 or Artillery)
- Sentry error tracking
- PagerDuty or Slack alert integration
- Deployment playbook and runbook
- One year of infrastructure support
