Leading Backend API Development FirmAPI Development
We build secure, scalable backend APIs in 12 weeks or less. Your product ships with a production-ready API, not a prototype.
IRPR is a leading backend API development firm that builds production-grade APIs using Node.js, Go, Python, and TypeScript. Our engineers design REST, GraphQL, and gRPC APIs with auto-generated documentation and automated testing.
A production-ready backend API ships in 8-12 weeks with a fixed price from $80K to $250K. Every API passes HIPAA, PCI-DSS, or SOC 2 compliance depending on your industry.
We work with CTOs who need a scalable API for their SaaS product, founders launching a mobile app that requires a robust backend, and enterprise teams migrating monolithic systems to microservices. VCs funding pre-seed startups also trust IRPR for API-first product development.
Types of software we ship.
REST API Development
Build stateless, cacheable REST APIs with Express.js or FastAPI. Include OpenAPI 3.0 specs and rate limiting out of the box.
GraphQL API Development
Design flexible GraphQL APIs using Apollo Server or Yoga. Enable precise data fetching for mobile and web clients.
gRPC API Development
Implement high-performance gRPC APIs with Protocol Buffers. Ideal for internal microservices and real-time streaming.
Microservices API Gateway
Deploy an API gateway (Kong or Envoy) to route requests across microservices. Include auth, logging, and load balancing.
Third-Party API Integration
Integrate with Salesforce, HubSpot, Stripe, and 50+ other APIs. Handle pagination, rate limits, and webhooks automatically.
Payment Gateway API
Build secure payment APIs using Stripe, Braintree, or Adyen. Handle subscriptions, refunds, and PCI compliance.
Real-Time API (WebSockets)
Develop real-time APIs with Socket.io or Pusher for live chat, notifications, and data sync. Latency under 100ms.
Data & Analytics API
Create analytical APIs that aggregate data from multiple sources. Use Redis caching and Elasticsearch for fast queries.
We build for every business type.

Backend API Development by the Numbers
We have delivered over 200 backend APIs for clients in 50+ countries.
Every API we build is designed to handle production traffic from day one. Our engineers write 100% test coverage and deploy APIs on AWS with auto-scaling.
Our clients see measurable results: 40% faster time-to-market compared to in-house teams and 50% fewer production incidents due to rigorous load testing.
Why Choose a Leading Backend API Development Firm
Most agencies deliver incomplete APIs with no documentation or tests.
Generic development shops treat APIs as an afterthought. They ship endpoints without rate limiting, auth, or monitoring, leaving you with technical debt.
IRPR delivers a production-grade API from day one. Our engineers follow a strict checklist that includes OpenAPI specs, automated tests, and deployment pipelines.
- OpenAPI specs are an afterthought
- No rate limiting or auth
- One monolithic endpoint
- No CI/CD pipeline
- No load testing
- No compliance built in
- OpenAPI 3.0 spec delivered day one
- Built-in API key auth and JWT
- Microservices with API gateway
- CI/CD with automated tests
- Load testing to 10,000 req/s
- HIPAA/PCI/SOC 2 by design
Our Backend API Development Process
From idea to production in 4 phases.
We follow a structured process that eliminates guesswork. Every phase produces a concrete artifact you can review.
The Roadmap phase (2 weeks) defines every endpoint and data model. Development runs 6-10 weeks with weekly demos.

What we ship in this practice.
Fintech Payment API
Built a REST API for a payment processing startup that handles 1,000+ transactions per second. Used Go, PostgreSQL, and Stripe Connect. Reduced transaction failures by 40%.
Healthcare Patient API
Developed a HIPAA-compliant GraphQL API for a telehealth platform. Used Node.js, AWS Lambda, and DynamoDB. Cut patient data retrieval time from 5 seconds to 200ms.
SaaS Integration API
Created a unified API for a CRM platform connecting to Salesforce, HubSpot, and Zoho. Used TypeScript and NestJS. Saved the client $50K/year in manual integration maintenance.
Ecommerce Inventory API
Engineered a real-time inventory API for a multi-warehouse retailer using gRPC and Redis. Syncs inventory across 10 locations in under 1 second. Eliminated overselling entirely.
Real Estate MLS API
Designed a RESTful API to aggregate MLS data from 15 sources for a property search app. Used Python, FastAPI, and Elasticsearch. Reduced data latency by 60%.
Logistics Tracking API
Built a WebSocket-based real-time tracking API for a fleet management platform. Used Node.js and Socket.io. Enabled live driver location updates every 5 seconds.
