Best API Development ConsultantsAPI Development
We build production APIs that ship in 8-12 weeks. Senior engineers only, fixed pricing from $80K.
IRPR builds production-grade APIs for web and mobile applications. We use Node.js, Python, Go, GraphQL, and REST to deliver scalable APIs that handle millions of requests per day.
Every API 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.
We work with CTOs who need a secure API for their fintech startup, VP of Engineering at a healthcare SaaS, product managers launching a mobile app, and enterprise architects modernizing legacy systems.
Types of software we ship.

Why IRPR is the best API development consultant
We measure what matters.
Every API we build is designed for production from day one. Our team of senior engineers has shipped over 200 products across 50 countries, with a 98% on-time delivery rate.
We focus on performance, security, and maintainability. Our APIs consistently achieve 99.9% uptime and handle thousands of requests per second.
Generic dev shop vs IRPR
Most API projects fail due to poor architecture and no security.
Generic dev shops often skip API design standards, deliver without rate limiting, and never provide documentation. Their hourly billing model encourages scope creep.
IRPR treats every API as a product. We use contract-first design, enforce security from day one, and charge a fixed price so you know the cost upfront.
- No API design standards
- No rate limiting
- No documentation
- No CI/CD
- No security audits
- Hourly billing
- REST/GraphQL design from day one
- Rate limiting and throttling
- Auto-generated OpenAPI docs
- CI/CD on GitHub Actions
- OWASP top 10 checks
- Fixed price per project
Our API development process
We follow a proven 4-phase framework.
From idea to release, our process ensures your API is built right the first time. Each phase has clear deliverables and a go/no-go decision point.
The entire lifecycle takes 8-12 weeks. You get weekly demos and a production-ready API at the end.
What ships with your API
Every deliverable is production-ready.
You get everything you need to deploy, maintain, and scale your API. No loose ends.
- Source code in your repo
- CI/CD pipeline on GitHub Actions
- OpenAPI 3.0 specification
- Postman collection
- Rate limiting middleware
- Authentication (JWT/OAuth)
- Error tracking with Sentry
- Performance benchmarks
- Load testing results
- Security audit report
What we ship in this practice.

Notification API for media
Engineered a WebSocket notification API for a news app, reducing delivery latency to under 100ms. Supports push, email, and SMS. Tech: Python, FastAPI, Firebase Cloud Messaging, Twilio.
Why teams hire us.
Fixed price, not hourly
Every API project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges.
Senior engineers only
Our team averages 10+ years of experience. Every engineer has shipped production APIs at scale. We do not outsource or use junior developers.
8-12 week delivery
Your API ships in 8 to 12 weeks. We use a lean process with weekly demos so you see progress every step.
Full code ownership
You own 100% of the source code and IP. No licenses, no recurring fees. The code is deployed to your infrastructure from day one.
Security-first approach
We implement OWASP top 10 controls, encrypt data at rest and in transit, and run third-party penetration tests before launch.
Post-launch support
We provide 30 days of post-launch support for any issues or minor changes. Extended maintenance plans are available if needed.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
