Leading Backend API Development PartnerAPI Development
We build REST, GraphQL, and microservices APIs that scale. 200+ products shipped, 50+ countries, fixed pricing from $80K.
IRPR is a leading backend API development partner. We build production-grade APIs using Node.js, Python (FastAPI, Django), Go, and .NET Core. Every API we ship includes OpenAPI/Swagger docs, automated tests, and CI/CD pipelines.
A typical backend API project takes 8-12 weeks for an MVP with fixed pricing between $80K and $250K. We handle compliance for HIPAA, PCI-DSS, and SOC 2. Our APIs average 99.9% uptime across 200+ deployments.
CTOs hire us when their in-house team lacks API expertise. Startup founders hire us to build their first product backend. Enterprise VPs hire us to modernize legacy APIs. We build for healthcare, fintech, ecommerce, SaaS, and logistics.
Types of software we ship.
REST API development
Build HTTP APIs with JSON payloads. Use Express.js, FastAPI, or Spring Boot. Includes rate limiting and caching with Redis.
GraphQL API development
Build queryable APIs with Apollo Server or Hasura. Clients fetch exactly what they need. Includes schema stitching and federation.
Microservices API development
Decouple monoliths into independent services. Use Docker, Kubernetes, and message queues like RabbitMQ or Kafka.
WebSocket API development
Build real-time APIs for chat, live updates, and streaming. Use Socket.io, WebSocket API, or MQTT. Supports 10K+ concurrent connections.
gRPC API development
Build high-performance APIs with Protocol Buffers. Use gRPC for internal service-to-service communication. 10x faster than REST for binary data.
Third-party API integration
Connect your app to Stripe, Salesforce, HubSpot, Twilio, or any REST/SOAP API. Includes error handling and retry logic.
API gateway and proxy
Deploy an API gateway with Kong, NGINX, or AWS API Gateway. Handle authentication, rate limiting, and request routing in one layer.
Serverless API development
Build APIs on AWS Lambda, Google Cloud Functions, or Azure Functions. Auto-scale to zero. Pay per request. Ideal for event-driven systems.
We build for every business type.
Fintech and banking
Healthcare and life sciences
Ecommerce and retail
SaaS and platform companies
Logistics and supply chain
Why choose IRPR as your leading backend API development partner
We ship APIs that handle millions of requests per day with 99.9% uptime.
IRPR has built backend APIs for 200+ products across 50+ countries. Our senior engineers use Node.js, Python, Go, and .NET Core. Every API includes OpenAPI documentation, automated test suites, and CI/CD pipelines.
We start with a 2-week Roadmap phase to define endpoints, data models, and integration points. Fixed pricing means no surprises. Typical MVPs ship in 8-12 weeks. Our APIs handle 10,000+ requests per second on standard infrastructure.
The difference between a generic agency and IRPR
Most agencies bill by the hour and deliver incomplete APIs. We do the opposite.
Generic dev shops often write vague scopes and charge for every change. They use junior developers who have never shipped a production API. Their APIs lack documentation, monitoring, and proper error handling.
IRPR assigns senior engineers only. We deliver a fully documented API with OpenAPI specs, automated tests, and a monitoring dashboard (Datadog or Sentry). You own the code from day one. No monthly retainers.
- Hourly billing with no cap
- Junior developers with 0-2 years experience
- No API documentation
- No automated tests
- No CI/CD pipeline
- Code ownership unclear
- Fixed price from $80K
- Senior engineers with 10+ years experience
- OpenAPI/Swagger docs included
- 100% test coverage on critical paths
- CI/CD on GitHub Actions or GitLab CI
- Full code ownership, no strings
Our API development process
We follow a 4-phase process that takes 8-12 weeks for an MVP.
Every project starts with a 2-week Roadmap phase. We define all endpoints, data models, authentication flows, and integration points. You get a detailed spec and a fixed price before we write a line of code.
The Build phase uses continuous delivery. You see working endpoints every 2 weeks. The Release phase includes load testing, security audit, and deployment to your cloud (AWS, GCP, or Azure).
What ships with every API
You get more than just code. Every delivery includes production-ready infrastructure.
When we finish a project, you receive a complete package. Source code in your Git repo, CI/CD pipeline, monitoring dashboards, and documentation. No handoff gaps, no missing pieces.
Everything is designed to run without us. Your team can extend the API, add endpoints, and deploy changes. We provide a handoff session to walk through the architecture.
- Source code in your GitHub/GitLab repo
- CI/CD pipeline with GitHub Actions or GitLab CI
- OpenAPI 3.0 documentation (Swagger UI)
- Automated test suite with 90%+ coverage
- Docker containers for local development
- Kubernetes manifests or Terraform scripts
- Sentry error tracking and Datadog monitoring
- Rate limiting and API key management
- Load test report with k6 or Locust
- Security audit report with OWASP ZAP
