Professional API Development ConsultantsAPI Development
We build APIs that connect your systems and scale with your business. 200+ products shipped in 12 weeks or less.
IRPR builds production-grade APIs for startups and enterprises. We use REST, GraphQL, and gRPC with Node.js, Python, Go, and PostgreSQL to create fast, secure integrations.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle compliance for HIPAA, PCI-DSS, SOC 2, and FERPA so your API passes audits from day one.
CTOs hire us to replace legacy integrations. Product managers hire us to launch API-first products. Engineering leads hire us to build internal microservices that reduce latency by 40% or more.
Types of software we ship.
REST API development
Build stateless RESTful APIs with OpenAPI specs, JWT auth, and rate limiting. Integrates with Stripe, Twilio, and AWS.
GraphQL API development

Why hire professional API development consultants
Building an API in-house takes 6 months and costs 3x more than hiring IRPR.
IRPR has shipped 200+ API projects across 50 countries. Our senior engineers average 10+ years of experience. We use a fixed-price model so you know the cost before we write a line of code.
Every API we build includes automated testing, CI/CD pipelines, and monitoring with Datadog or Sentry. We guarantee 99.9% uptime and full code ownership. No black boxes, no vendor lock-in.
Generic dev shop vs IRPR API consultants
Most agencies deliver late, over budget, and without documentation. IRPR does the opposite.
Generic shops often use junior developers, change scope mid-project, and hand over code with no tests. You end up with a fragile API that breaks in production.
IRPR assigns senior engineers only. We write automated tests, generate OpenAPI docs, and deploy on your AWS or GCP account. You get a production-ready API in 12 weeks or less.

How IRPR builds your API in 4 phases
From idea to production in 12 weeks with no surprises.
Phase 1 (Idea): We map your data model, endpoints, and auth strategy. You get a detailed API specification in week 1.
Phase 2 (Roadmap): We estimate every endpoint, write acceptance criteria, and lock the price. You approve before we build.
What ships with every API project
You get more than just code. Every deliverable is production-ready.
IRPR includes everything you need to run and maintain your API. No hidden costs, no missing pieces.
All source code is in your GitHub repo. We set up CI/CD, monitoring, and documentation so your team can take over immediately.

- CI/CD pipeline with GitHub Actions and Docker
- Automated test suite with 90%+ coverage
- OpenAPI 3.0 specification and Swagger UI
- Rate limiting and authentication (JWT or OAuth2)
- Error tracking with Sentry
- Performance monitoring with Datadog
- Deployment scripts for AWS, GCP, or Azure
- 30 days of post-launch support and bug fixes
- Full documentation for developers and operations
What we ship in this practice.
Healthcare patient data API
Built a HIPAA-compliant REST API for a telehealth startup. Integrated with Epic and Cerner EHRs. Reduced patient data retrieval time from 4 seconds to 200ms. Tech stack: Node.js, PostgreSQL, AWS Lambda, Twilio.
Fintech payment aggregation API
