We build secure, scalable REST APIs for your product. Ship in 8-12 weeks with a fixed price.
IRPR builds custom REST APIs for startups and enterprises. We use Node.js, Python, Go, and frameworks like Express, FastAPI, and Gin.
An API project ships in 8-14 weeks with a fixed price of $80K-$250K. We handle compliance for healthcare (HIPAA) and fintech (PCI-DSS).
We work with CTOs needing a production-ready API, founders launching a SaaS MVP, product managers scaling a platform, and engineering leads outsourcing API development.

Generic dev shop vs. IRPR API consultants
Not all API development is the same. Here is what sets IRPR apart.
Most agencies start coding without a clear contract. You pay hourly and hope for the best.
IRPR gives you a fixed price and a detailed roadmap in week 2. No surprises.
- Hourly billing with no cap
- No API specification first
- Manual deployment
- No monitoring or error tracking
- Unknown team composition
- No compliance support
- Fixed price from the start
- OpenAPI spec before coding
- Automated CI/CD pipeline
- Sentry + Datadog monitoring
- Senior engineers only (12+ yrs avg)
- HIPAA/PCI/SOC 2 ready
How we build your REST API
A structured 4-phase process from idea to production.
Phase 1: Idea validation and API design. We map endpoints, data models, and authentication. You get a detailed roadmap with fixed price.
Phase 2-4: Sprint-based development, integration testing, and deployment. Handoff includes full documentation and source code.
What ships with your REST API
Every API project includes these deliverables.
We do not just give you code. You get a production-ready system with monitoring and documentation.
All artifacts are in your repository from day one.
- OpenAPI 3.0 specification
- Postman collection with examples
- CI/CD pipeline (GitHub Actions or GitLab CI)
- Automated unit and integration tests (90%+ coverage)
- Docker container setup
- Sentry error tracking
- Datadog performance monitoring
- Source code in your private GitHub repo
- Deployment playbook for AWS/GCP
- 30-day post-launch support
What we ship in this practice.
