Premium API Development ConsultantsAPI Development
We build production-grade APIs for startups and enterprises. 200+ products shipped, 8-12 week delivery, fixed pricing.
IRPR builds premium APIs for companies that need reliable, secure, and scalable integrations. We use Node.js, Go, Python, and TypeScript with frameworks like Express, Fastify, Apollo Server, and gRPC. Every API is designed with OpenAPI 3.0 specs and tested with Postman and Jest.
We ship a production-ready API in 8-12 weeks. Pricing starts at $80K and goes to $250K for complex multi-service architectures. All projects include HIPAA, PCI-DSS, or SOC 2 compliance documentation. You get full source code ownership and a CI/CD pipeline on GitHub Actions.
CTOs hire us when their in-house team lacks API security expertise. Product managers hire us to build a public API for their SaaS platform. Startup founders hire us to create the backend for their mobile app. Enterprise architects hire us to modernize legacy SOAP APIs to REST or GraphQL.
Types of software we ship.

Why Hire Premium API Development Consultants
Building a production-grade API requires more than just code. It needs security, documentation, monitoring, and compliance.
IRPR has shipped over 200 APIs for clients in 50 countries. Our APIs handle millions of requests per day with 99.9% uptime. We use automated testing with Jest and Supertest to catch regressions before they reach production.
Every API we build includes rate limiting, authentication (JWT or OAuth 2.0), and structured logging with Sentry. We deploy on AWS ECS or Kubernetes with auto-scaling. You get a Grafana dashboard for real-time monitoring.
Generic Dev Shop vs Premium API Consultants
Not all API development teams deliver the same quality. Here is what sets IRPR apart.
Generic dev shops often skip API documentation, security audits, and performance testing. They deliver code that works but fails under load or fails a compliance audit.
IRPR treats every API as a product. We write OpenAPI specs before writing code. We run load tests with k6. We document every endpoint with request/response examples. Your API ships with a Postman collection and a CI/CD pipeline.
- No API documentation
- No load testing
- No security audit
- No CI/CD pipeline
- No monitoring setup
- No compliance support
- OpenAPI 3.0 specs from day one
- k6 load testing for 10K+ concurrent users
- OWASP Top 10 security review
- GitHub Actions CI/CD with automated tests
- Sentry error tracking and Grafana dashboards
- HIPAA, PCI-DSS, or SOC 2 compliance docs
Our API Development Process
We follow a four-phase process that delivers a production-ready API in 8-12 weeks.
Phase 1 is the Roadmap. We define endpoints, data models, auth strategy, and compliance requirements. You get a fixed price and timeline. Phase 2 is the Build. We write code in 2-week sprints with daily standups and weekly demos.
Phase 3 is the Release. We deploy to staging, run load tests, and fix any issues. You get a production deployment with monitoring. Phase 4 is the Handoff. We transfer full source code, documentation, and runbooks to your team.
What Ships With Every API
Every API project includes these deliverables by default. No hidden costs.
We believe in full transparency. Every deliverable is listed in the Roadmap phase. You know exactly what you get before we write a line of code.
All deliverables are stored in your GitHub repository. You own everything from day one.
- Source code in your GitHub repo
- OpenAPI 3.0 specification
- Postman collection with example requests
- CI/CD pipeline on GitHub Actions
- Sentry error tracking
- Grafana monitoring dashboard
- Load test results from k6
- Security audit report (OWASP Top 10)
- Deployment runbook for AWS or GCP
- HIPAA, PCI-DSS, or SOC 2 compliance documentation
