Professional Backend API Development ServicesBackend API
We build reliable, scalable APIs that power your products. 200+ APIs shipped with 99.9% uptime.
IRPR builds professional backend API development services using Node.js, Python, Go, and PostgreSQL. Each API is designed for high throughput and low latency with Redis caching and message queues like RabbitMQ.
Most projects ship in 8-12 weeks with a fixed price between $80,000 and $250,000. We deliver HIPAA-compliant healthcare APIs, PCI-DSS compliant payment APIs, and SOC 2 compliant enterprise APIs.
CTOs scaling their platform hire us to replace brittle legacy integrations. Founders launching a SaaS product need a production-ready API from day one. Enterprise teams outsource custom API layers to avoid hiring a full backend team.
Types of software we ship.
REST API Development
Stateless endpoints with full CRUD, pagination, and rate limiting. Uses Express.js or FastAPI with PostgreSQL.
GraphQL API Development
Flexible queries and mutations with Apollo Server and Prisma. Reduces over-fetching on mobile apps.
Microservices API Development
Independent services communicating via gRPC or message queues. Deployed on Kubernetes with Docker.
API Gateway Development
Centralized authentication, rate limiting, and routing using Kong or AWS API Gateway. Handles 10,000+ requests per second.
Webhook System Development
Real-time event notifications with retry logic and delivery logs. Built with Node.js and Redis to guarantee delivery.
API Integration Layer
Middleware that connects your product to Salesforce, Stripe, or HubSpot. Uses a unified schema with transformation logic.
Real-Time API (WebSocket)
Low-latency bidirectional communication for live dashboards and chat. Powered by Socket.io or WebSocket with Redis pub/sub.
Backend as a Service (BaaS)
Full backend stack with authentication, file storage, and serverless functions. Deployed on Firebase or Supabase with auto-scaling.
We build for every business type.
SaaS Platforms
Fintech Apps
Healthcare Systems
Ecommerce
Enterprise Software
Why Professional Backend API Development Matters
Your API is the backbone of your product. A poorly built one breaks under load and leaks data.
IRPR builds APIs that handle thousands of requests per second with 99.9% uptime. We enforce OAuth 2.0, JWT, and API keys for authentication. Every endpoint is documented with OpenAPI and tested for edge cases.
We use load testing with k6 to verify throughput before launch. Our APIs include rate limiting, logging, and monitoring via Datadog or Sentry. The result is a backend that scales as your user base grows.
Generic Shops vs IRPR
Most dev shops deliver an API that works once and breaks the next week. IRPR delivers a production system.
Generic shops write code in a silo, skip security reviews, and hand you a tarball. IRPR builds your API in your own GitHub repo, runs automated CI/CD, and deploys to your cloud account.
We include unit tests, integration tests, and a staging environment. Every API comes with a maintenance handbook and 30 days of post-launch support.
- No API security review
- No load testing before launch
- No API documentation generated

- OAuth 2.0 + JWT + API keys enforced
- k6 load testing at 10,000 req/s
- Swagger/OpenAPI docs auto-generated
- GitHub Actions CI/CD pipeline
- Sentry + Datadog monitoring included
- Rate limiting, throttling, and IP whitelisting
How We Build Your Professional Backend API
Our process is designed to de-risk your project from day one. You see working code every week.
We start with a 1-week discovery phase to map your data model, user flows, and performance requirements. Then we write a fixed-price Roadmap. No surprises.
Each sprint ends with a demo. By week 4 you have a working API in staging. By week 12 your production API is live with monitoring and documentation.
What Ships in Every Backend API Project
Every IRPR project delivers a complete, production-ready system. No missing pieces.
You receive the full source code with a license to do whatever you want. We deploy to your own AWS or GCP account so you retain control.
All projects include automated tests, CI/CD, and monitoring. You can pause or extend the retainer at any time.
- Source code in your private GitHub repo
- API documentation with Swagger/OpenAPI
- CI/CD pipeline with GitHub Actions
- Sentry error tracking and Datadog monitoring
- AWS or GCP deployment with Terraform scripts
- Load testing report from k6 (10,000 req/s)
- Rate limiting, JWT, and OAuth 2.0 implementation
- Unit test suite with 90%+ coverage
- API versioning strategy (URL or header)
- Post-launch setup session for your team
What we ship in this practice.
Payment Processing API for Fintech
Built a PCI-DSS compliant API that handles 500+ transactions per second. Integrated with Stripe and Plaid. The startup reduced payment failures by 40% and passed their SOC 2 audit. Tech stack: Node.js, PostgreSQL, Redis, Stripe SDK.
Patient Data API for Telemedicine
Developed a HIPAA-compliant API to sync patient records between EHRs and a telehealth platform. Endpoints handle 1,200 requests per minute with encrypted payloads. The client went from paper logs to real-time data. Tech stack: Python FastAPI, PostgreSQL, FHIR standard.
Order Management API for Ecommerce
Created a REST API that connects Shopify, warehouse WMS, and shipping carriers. Automatically syncs inventory across 3 locations. The brand reduced manual order entry by 8 hours per week. Tech stack: Ruby on Rails, PostgreSQL, Shopify API, EasyPost.
SaaS Subscription API for CRM Startup
Built a GraphQL API for user management, plan upgrades, and billing. Handles 50,000 users with multi-tenancy. The startup raised Series A after demonstrating the API's scalability. Tech stack: Node.js Apollo Server, Prisma, Stripe, AWS EKS.
Real-Time Analytics API for Media Platform
Developed a WebSocket API pushing live metrics to front-end dashboards. Processes 10,000 events per second with 200ms latency. The platform improved user engagement by 25%. Tech stack: Node.js, WebSocket, Redis, Kafka, TimescaleDB.
IoT Data Ingestion API for Manufacturing
Built a high-throughput API that ingests sensor data from 500 factory machines. Uses MQTT bridge and stores time-series data in InfluxDB. The client reduced unplanned downtime by 30%. Tech stack: Go, MQTT, InfluxDB, PostgreSQL, Grafana.
Why teams hire us.
Fixed price, not hourly
Every IRPR project gets a fixed quote after the Roadmap phase (week 2). You know the total cost before we start coding. No hourly billing, no surprise invoices.
Senior engineers only (10+ years)
Our team averages 12 years of backend experience. No junior developers on your API. Every architect has built systems handling 10,000+ requests per second.
HIPAA/PCI/SOC 2 compliant by default
We build compliance into every API layer from day one. Encrypted storage, audit logs, and role-based access control are standard. Your API passes audits without rework.
Agile with weekly demos
You see working code every Friday. We deploy to staging after each sprint. No long periods of silence. You can pivot early if needed.
Post-launch support included
Every project includes 30 days of post-launch support. We fix bugs, answer questions, and help your team take over. Retainers available after that at $5,000/month.
Full code ownership
You own the entire source code, documentation, and deployment scripts. No IRPR license restrictions. You can modify, sell, or open-source the API as you wish.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
