Backend API Development AgencyAPI Development
We build production-ready backend APIs in 8-12 weeks. REST, GraphQL, or gRPC -- fixed price, full ownership.
IRPR is a backend API development agency that builds custom APIs using Node.js, Python, Go, and PostgreSQL. We design RESTful and GraphQL endpoints with OpenAPI specs and automated testing via Postman and Jest.
Every API project ships in 8-12 weeks with fixed pricing from $80K to $250K. We handle compliance for HIPAA, PCI-DSS, and SOC 2. You get full source code ownership, CI/CD pipelines, and Sentry error monitoring.
We work with CTOs launching new products, engineering managers scaling microservices, healthcare vendors needing HIPAA compliant APIs, and fintech startups requiring PCI-DSS level security.

Backend API Development Agency by the Numbers
Our track record proves we deliver reliable APIs on time.
IRPR has shipped 200+ API projects across 50+ countries. Our APIs power ecommerce checkout flows, healthcare data exchange, and fintech payment processing.
We maintain a 98% on-time delivery rate and 99.9% API uptime. Every API goes through automated testing and security scanning before launch.
Generic Dev Shop vs IRPR: The API Difference
Not all agencies build APIs the same way.
A generic dev shop might deliver an undocumented API with no CI/CD and hidden costs. IRPR provides OpenAPI specs, automated deployments, and a fixed price from day one.
Your backend API needs security, scalability, and documentation. Our process delivers all three without surprises.
- No OpenAPI specs
- Hourly billing ambiguity
- No CI/CD pipeline
- No security audit
- One-size-fits-all stack
- Vague timeline
- OpenAPI 3.0 documentation
- Fixed price from Roadmap
- GitHub Actions CI/CD
- HIPAA/PCI/SOC2 audits
- Node/Python/Go + PostgreSQL
- 8-12 week delivery

Why teams hire us.
Fixed Price from Day 1
Every API project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices. Our 98% on-time rate means you pay what was quoted.
Senior Engineers Only
We assign engineers with 8+ years of experience in backend development. No junior devs. Your API is built by senior Node, Python, or Go developers who have shipped 200+ products.
Full Code Ownership
You own 100% of the source code, documentation, and IP. We don't license or reuse your API code. After launch, you can take the code anywhere.
HIPAA, PCI, SOC 2 Compliance Built In
We include security compliance in the build process, not as an add-on. Our APIs are audited for HIPAA privacy rules, PCI-DSS cardholder data, and SOC 2 controls.
8-12 Week Delivery
From Idea to Release in 8-12 weeks. We work in 2-week sprints with demos every sprint. You see working endpoints by week 4.
Post-Launch Monitoring and Support
We deploy with Sentry error tracking and PagerDuty alerts. You get 30 days of warranty support. If something breaks, we fix it within 24 hours.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
