Experienced Backend API Development DevelopersBackend API
Build production-grade APIs with engineers who have shipped 200+ products. Get your MVP in 8-12 weeks with fixed pricing.
IRPR builds backend APIs using modern stacks like Node.js, Python (Django/FastAPI), and Go. We design RESTful and GraphQL endpoints with PostgreSQL, Redis, and Kubernetes for scalability.
We ship a production-ready API in 8-12 weeks. Pricing is fixed at $80K-$250K depending on scope. Our APIs meet compliance standards like HIPAA, SOC 2, and PCI-DSS.
We work with CTOs needing a scalable data layer, product managers launching SaaS platforms, and startup founders building their first API product. We also partner with agencies needing senior backend talent.
Types of software we ship.
REST API Development

Media & Content
Why experienced backend API developers matter
A poorly designed API costs time and money. Our APIs are built for scale from day one.
We design endpoints with clear separation of concerns, caching strategies, and proper error handling. Our APIs handle millions of requests per month with 99.9% uptime.
We use load testing (k6) and automated monitoring (Datadog) to ensure performance. Every API ships with documentation (Swagger) and a test suite (Jest).
The difference between generic developers and IRPR
Not all backend developers are equal. Here's what we do differently.
Generic freelance developers often skip testing and documentation. We ship production-ready code with CI/CD, monitoring, and full test coverage.
IRPR provides a single point of contact, weekly updates, and a fixed price. You get the code in your repo from day one.
- No API documentation
- No load testing
- No CI/CD pipeline
- Hourly billing with scope creep
- No post-launch monitoring
- Unclear ownership of code
- OpenAPI/Swagger docs included
- k6 load testing
- GitHub Actions CI/CD
- Fixed price based on Roadmap
- Datadog monitoring and alerts
- You own all source code
Our 4-phase backend API development process
We follow a structured process to deliver your API on time and on budget.
We start every project with a 2-week Idea phase to understand your data requirements and endpoints. You get a full API specification and a fixed price quote.
During the Roadmap phase we define data models, endpoints, and auth flows. Then we build iteratively with weekly demos and full test coverage.
What ships with every backend API
We don't just hand over code. Here's what you get automatically.
Our delivery includes everything needed to run and maintain your API in production.
- Source code in your private GitHub repository
- OpenAPI 3.0 documentation (Swagger UI)
- CI/CD pipeline with GitHub Actions
- Unit and integration tests (Jest)
- Postman collection for testing
- Database migration scripts
- Docker containers for local development
- Sentry error tracking integration
- Datadog dashboard for monitoring
- Post-launch support engineer for 30 days
What we ship in this practice.
Payment processing API for fintech startup
Built a RESTful payment API in 10 weeks using Node.js, PostgreSQL, and Stripe Connect. The API processed $2.5M in transactions in the first month with 99.9% uptime.
Patient data API for telehealth platform
Developed a HIPAA-compliant GraphQL API with FastAPI and Azure FHIR. Reduced patient record retrieval time by 60%, handling 50K requests/hour.
Order management API for ecommerce brand
Created a microservices-based order API with Go, gRPC, and PostgreSQL. Integrated with Shopify and ShipStation, reducing order processing errors by 95%.
Content delivery API for media platform
Built a real-time streaming API with Node.js, WebSockets, and AWS MediaConvert. Delivered 100TB of video monthly with sub-2-second latency.
Inventory API for logistics company
Developed a RESTful inventory API using Python (Django) and Redis. Consolidated data from 3 warehouse systems, reducing stock discrepancies by 80%.
CRM API for real estate SaaS
Designed a multi-tenant GraphQL API with PostgreSQL and Apollo Server. Handled 1M+ property records across 20 markets with <100ms response times.
Why teams hire us.
Fixed price, not hourly
We give you a fixed quote after the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges.
Senior engineers only
Every developer on your project has 8+ years of experience building APIs at scale. Our team averages 10 years of production backend work.
Unlimited revisions during development
During the Product phase (weeks 3-12), we make unlimited changes to endpoints and logic. Your feedback is incorporated within 48 hours.
Code ownership from day one
You have full access to the source code repository from the first commit. There are no licensing fees or lock-in.
Compliance-ready APIs
We build APIs that meet HIPAA, SOC 2, PCI-DSS, and GDPR requirements. Our code passes third-party security audits.
Ongoing support after launch
We include 30 days of post-launch support with a dedicated engineer. After that, we offer maintenance at $5K/month.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
