Backend API Development StudioDevelopment Studio
Senior engineers build your API in 8-12 weeks. Fixed pricing, full ownership, production-ready from day one.
IRPR builds backend APIs for web and mobile applications. We use Node.js, Python, Go, and frameworks like Express, FastAPI, and GraphQL to deliver scalable endpoints that handle thousands of requests per second.
Each project ships with CI/CD pipelines, OpenAPI 3.0 documentation, error monitoring (Sentry), and performance monitoring (Datadog). Timeline is 8-12 weeks with a fixed price between $80K and $250K. Compliance options include HIPAA, PCI-DSS, and SOC 2.
Our clients are CTOs replacing legacy APIs, founders launching SaaS platforms with a core API, product managers integrating Stripe or Salesforce, and enterprises building secure microservices. All hire IRPR for senior engineering and predictable delivery.
Types of software we ship.
REST API Development
Stateless endpoints using JSON over HTTP. Built with Express or FastAPI, including rate limiting and authentication.
GraphQL API Development
Flexible queries for client-driven data fetching. Built with Apollo Server or Hasura, often paired with React and Next.js.
Microservices API Development
Containerized services communicating via gRPC or message queues. Deployed on Kubernetes with auto-scaling.
Webhook API Development
Event-driven callbacks for real-time integrations. Built with Express and deployed with retry logic and logging.
Real-Time API (WebSocket) Development
Persistent connections for live updates. Built with Socket.io or WebSocket API, used for chat, notifications, and dashboards.
API Gateway Development
Centralized routing, authentication, and rate limiting. Built with Kong, Nginx, or AWS API Gateway for multi-service architectures.
Internal API Development
Private APIs for business logic between services or for internal tools. Secured with OAuth2 and service mesh.
Third-Party API Integration
Connect your app to Stripe, Salesforce, Twilio, or 100+ other services. Built with middleware and retry patterns.
We build for every business type.
Healthcare
Fintech
Ecommerce
SaaS
Logistics
Why choose a dedicated backend API development studio?
IRPR delivers production-ready APIs with measurable results that generic freelancers rarely match.
Every API we build includes automated testing with >90% coverage, load testing with k6, and monitoring with Sentry and Datadog. This means fewer production incidents and faster debugging.
Our fixed-price model eliminates scope creep. In the Roadmap phase (week 2), you get a detailed specification with every endpoint, data model, and integration. The price does not change.
Generic developers vs. an API studio
The difference between code that works and code that scales.
Freelancers often deliver undocumented, untested APIs that break under load. IRPR builds APIs that are documented, tested, and monitored from day one.
Our senior engineers have 10+ years of experience. They have built APIs for healthcare, fintech, and ecommerce companies that handle millions of requests per day.

How we build your backend API in 8-12 weeks
Our process ensures clarity, speed, and quality from spec to deployment.
We start with a one-week Discovery phase to understand your data sources, integrations, and performance requirements. Then we create a fixed-price Roadmap with every endpoint specified.
Development happens in two-week sprints with continuous deployment. You see a working API by week 4.
What ships with your backend API?
Every project includes these deliverables by default - no add-ons needed.
When IRPR delivers your API, you get more than just code. You get a production-ready system with every tool you need to maintain and scale it.
- Source code in your private GitHub repo
- OpenAPI 3.0 specification
- CI/CD pipeline (GitHub Actions)
- API load testing results (k6)
- Error monitoring (Sentry)
- Performance monitoring (Datadog)
- Rate limiting and security headers
- Authentication with JWT or OAuth2
- Deployment scripts for AWS/GCP/Azure
- Developer documentation site (ReadMe or Docusaurus)
What we ship in this practice.
Telemedicine Appointment API
Built a FastAPI backend that handles scheduling, video call initiation, and patient record sync. Reduced appointment scheduling time by 40% for a healthcare startup. Tech stack: FastAPI, Twilio Video, PostgreSQL, Docker.
Payment Processing Microservice
Developed a Node.js microservice that processes Stripe payments, handles refunds, and logs transactions. Achieved 99.99% uptime and cut payment failures by 60%. Tech stack: Node.js, Stripe API, AWS Lambda, DynamoDB.
Real-Time Inventory Sync API
Built a GraphQL API with WebSocket subscriptions for an ecommerce platform. Inventory updates propagate to all storefronts in under 2 seconds. Reduced inventory errors by 90%. Tech stack: GraphQL, Apollo Server, Redis, PostgreSQL.
SaaS Subscription Management API
Created a REST API for user authentication, plan upgrades, and billing. Integrated with Stripe and Auth0. The client scaled from 0 to 10,000 users in 6 months without any API changes. Tech stack: Express, PostgreSQL, Auth0, Stripe.
Logistics Route Optimization API
Developed a microservice using gRPC and Google Maps API to compute optimal delivery routes. Reduced fuel costs by 15% and improved on-time delivery to 97%. Tech stack: Python, gRPC, Docker, Kubernetes, Google Maps API.
Healthcare Claims Processing API
Built a HIPAA-compliant API that validates and routes insurance claims in real time. Processed 50,000 claims per day with 99.5% accuracy. Tech stack: FastAPI, PostgreSQL, AWS KMS, FHIR standards.
