Top Backend API Development FirmAPI Development
We build production-grade APIs for SaaS platforms, fintech apps, and healthcare systems. Fixed price, 12-week delivery, full compliance.
IRPR is a top backend API development firm. We build REST, GraphQL, and gRPC APIs using Node.js, Python, Go, and PostgreSQL. Every API is designed for low latency, high throughput, and easy integration.
Most MVPs ship in 12 weeks. Prices range from $80K to $250K. We handle HIPAA, PCI-DSS, and SOC 2 compliance. You get a fixed price quote in week 2 of the project.
We work with CTOs who need a scalable API for a new product. We help founders who want to replace a slow legacy backend. We serve engineering VPs who need a compliant API for healthcare or fintech. We build for product managers who need integrations with Stripe, Salesforce, and HubSpot.
Types of software we ship.
RESTful API Development
Create stateless, cacheable APIs for web and mobile apps. We use Express.js, FastAPI, and Django REST Framework.
GraphQL API Development
Build flexible APIs that let clients query exactly what they need. We use Apollo Server and Hasura.
Microservices API Development
Decompose monoliths into independent services. We use Docker, Kubernetes, and message queues like RabbitMQ.
Third-Party API Integration
Connect your app to Stripe, Twilio, Salesforce, and 50+ other services. We handle OAuth, webhooks, and rate limiting.
Real-Time API Development
Build WebSocket and SSE APIs for live dashboards, chat, and notifications. We use Socket.io and Redis Pub/Sub.
API Gateway and Management
Deploy API gateways with Kong or AWS API Gateway. We add authentication, throttling, and analytics.
Internal API Development
Design APIs for internal tools and service-to-service communication. We use gRPC and Protobuf for high performance.
API Documentation and Testing
Generate OpenAPI specs, Postman collections, and automated tests. We use Swagger and Jest for full coverage.
We build for every business type.

Why a Top Backend API Development Firm Matters
A poorly designed API costs you time, money, and customers.
Many teams build APIs that are slow, insecure, and hard to maintain. They use outdated tools or skip testing. That leads to downtime, data leaks, and integration headaches.
IRPR builds APIs that scale. We use Node.js, Python, Go, and PostgreSQL. Every API gets automated tests, monitoring with Datadog, and a CI/CD pipeline on GitHub Actions. Our APIs handle millions of requests per day.
How IRPR Stands Out from Other API Agencies
Most dev shops bill hourly and deliver late. We do not.
Generic agencies often use junior developers and change requirements mid-project. They deliver incomplete code with no documentation. You pay for every extra hour.
IRPR assigns senior engineers only. We give you a fixed price after a 2-week Roadmap phase. You get full source code, OpenAPI docs, and a deployment playbook.
- Hourly billing with no cap
- Junior developers with no API experience
- No automated tests
- No API documentation
- Unclear timeline and scope creep
- No compliance support
- Fixed price quoted in week 2
- Senior engineers only (8+ years experience)
- 100% test coverage with Jest and Postman
- OpenAPI 3.0 docs auto-generated
- 12-week delivery with weekly demos
- HIPAA, PCI-DSS, SOC 2 compliance built in
Our API Development Process in 4 Phases
We follow a repeatable process that de-risks your project.
Every project starts with a Roadmap phase. We define the API endpoints, data models, and integration points. You get a fixed price and a detailed plan.
Then we build the API in 2-week sprints. You see working code every sprint. We deploy to staging and run load tests. The final phase is production deployment with monitoring.
What Ships with Your API
You get more than code. You get a production-ready system.
Every API project includes documentation, tests, and deployment scripts. You own everything. No black boxes, no vendor lock-in.
We also include a monitoring dashboard and a runbook for your ops team. You can deploy and maintain the API without us.
- Source code in your GitHub or GitLab repo
- OpenAPI 3.0 specification file
- Postman collection with example requests
- Automated test suite (unit + integration + e2e)
- CI/CD pipeline with GitHub Actions or GitLab CI
- Docker Compose file for local development
- Deployment scripts for AWS, GCP, or Azure
- Datadog monitoring and Sentry error tracking
- Runbook for on-call engineers
- One year of post-launch support
What we ship in this practice.
SaaS Platform API
Built a REST API for a subscription management platform. The API handles 10,000 requests per second with 50ms latency. Tech stack: Node.js, PostgreSQL, Redis, Stripe integration. Reduced billing errors by 40%.
Fintech Payment Gateway
Developed a PCI-DSS compliant API for a payment gateway. The API processes 500,000 transactions per day. Tech stack: Python, FastAPI, AWS Lambda, DynamoDB. Achieved 99.99% uptime in the first year.
Healthcare Data API
Created a HIPAA-compliant API for a telemedicine platform. The API syncs patient records across 50 clinics. Tech stack: Go, PostgreSQL, gRPC, AWS HealthLake. Reduced data sync time from 4 hours to 12 minutes.
Ecommerce Inventory API
Built a GraphQL API for a multi-warehouse inventory system. The API updates stock levels in real time across 10 warehouses. Tech stack: Node.js, Apollo Server, MongoDB, RabbitMQ. Eliminated overselling by 100%.
Real Estate MLS API
Developed a REST API for a real estate MLS platform. The API serves property listings to 500 brokerages. Tech stack: Ruby on Rails, PostgreSQL, Elasticsearch, Redis. Reduced listing update latency from 5 minutes to 2 seconds.
EdTech Assessment API
Created a FERPA-compliant API for an online assessment platform. The API handles 50,000 concurrent users during exam periods. Tech stack: Python, Django, PostgreSQL, WebSockets. Scaled from 1,000 to 50,000 users without downtime.
Why teams hire us.
Senior Engineers Only

Fixed Price, Not Hourly
You get a fixed price in week 2 after the Roadmap phase. No hourly billing, no surprise charges, no scope creep. If we add features, we quote them separately.
12-Week MVP Delivery
Most projects ship in 12 weeks. We use 2-week sprints with working software at the end of each sprint. You can launch faster and start testing with real users.
Full Compliance Built In
We build HIPAA, PCI-DSS, and SOC 2 compliance from day one. We handle audit logging, data encryption, access controls, and vulnerability scanning.
You Own Everything
Full source code, documentation, and deployment scripts are yours. No license fees, no ongoing royalties. You can take the code to any team.
Post-Launch Support Included
We include one year of support after launch. We monitor your API with Datadog and Sentry. We fix bugs and deploy patches within 24 hours.
