Expert Backend API Development StudioBackend API
We build production-ready APIs your engineers will love. 200+ products shipped, 50+ countries, fixed pricing from $80K.
IRPR is an expert backend API development studio that builds secure, scalable APIs using Node.js, Python, and Go. We design RESTful and GraphQL endpoints with OpenAPI specs from day one.
Every API project ships in 8-12 weeks with a fixed price of $80K-$250K. We handle authentication (OAuth 2.0, JWT), rate limiting, and database integration for PostgreSQL, MongoDB, or DynamoDB. Compliance with HIPAA, PCI DSS, and SOC 2 is built in from the start.
We work with CTOs who need to integrate external systems, product managers launching SaaS platforms with complex data flows, and engineering leads at fintech and healthcare companies who require API-first architectures.
Types of software we ship.
REST API Development
Build resource-oriented REST APIs with versioning, pagination, and caching. Uses OpenAPI 3.0 specs and Postman collections.
GraphQL API Development
Flexible GraphQL endpoints that let clients request exactly the data they need. Built with Apollo Server and TypeScript.
Microservices API Gateway
Centralized gateway for service discovery, authentication, and rate limiting. Powered by Kong or AWS API Gateway.
Third-Party API Integration
Connect to Stripe, Salesforce, HubSpot, or any external API. Uses idempotency keys and retry logic for reliability.
Internal API Platform
Private APIs for internal microservices with role-based access and audit logs. Built with gRPC or REST.
Real-Time API (WebSocket)
Bi-directional, low-latency APIs for live chat, notifications, and real-time dashboards using Socket.io or AWS AppSync.
Serverless API (AWS Lambda)
Cost-efficient, auto-scaling APIs with no server management. Uses Lambda, API Gateway, and DynamoDB.
Payment API Integration
Secure payment processing with Stripe, Braintree, or PayPal. Includes webhooks, idempotency keys, and PCI DSS compliance.
We build for every business type.

Why choose an expert backend API development studio
IRPR delivers production-grade APIs on time and on budget.
Every API we build starts with a detailed Roadmap phase (week 1-2). We define endpoints, data models, authentication flows, and error handling before writing a single line of code. This process eliminates surprises and ensures the API matches your exact business logic.
Our APIs are built for scale from day one. We use asynchronous workers (Bull, Celery) for heavy tasks, implement caching with Redis, and set up auto-scaling on Kubernetes or AWS ECS. Performance benchmarks are run before launch to guarantee sub-200ms response times at 10x your expected load.
The difference between a generic dev shop and IRPR
Not all API development is equal. Here is how we compare.
Generic development shops often treat APIs as an afterthought. They bill by the hour, skip API documentation, and leave you with fragile endpoints that break when traffic spikes. Security audits are rarely included, and you end up with tech debt that costs more to fix later.
IRPR treats your API as the core product. We start with a fixed price and a thorough Roadmap. Every endpoint is documented in OpenAPI 3.0, secured with OAuth 2.0, and tested for edge cases. You get a production-ready API with CI/CD, monitoring, and a 30-day support window.
- Hourly billing with no price cap
- No API design or documentation upfront
- Minimal security (no OAuth, no rate limiting)
- Slow delivery (4-6 months or more)
- No post-launch monitoring or support
- Code with hidden technical debt
- Fixed price after Roadmap phase (week 2)
- OpenAPI 3.0 specs and Postman collections from day one
- Security-first: OAuth 2.0, JWT, rate limiting, input validation
- 8-12 week MVP delivery
- Dedicated project manager and senior engineers
- Full code ownership, 30-day post-launch support
Our API development process in 4 phases
From idea to API in 8-12 weeks.
Every project follows a repeatable, transparent process. The Roadmap phase (week 1-2) defines the exact scope, endpoints, and timeline. After that, we move to designing, implementing, and deploying your API with weekly demos and feedback loops.
Throughout the process, you see exactly what we are building. We use GitHub boards, Slack, and bi-weekly calls to keep you informed. Changes are handled through a change request process with clear cost and time implications.
What ships with every API project
You get more than code. Here is what we deliver.
After the project, you own everything. Here is what ships with your API.
- Source code in your repo
- CI/CD pipeline (GitHub Actions or GitLab CI)
- OpenAPI 3.0 specification (spec file)
- Postman collection for testing endpoints
- API documentation (Swagger UI hosted on your domain)
- Sentry error tracking integrated
- Docker container setup for local development
- Cloud deployment scripts (Terraform or CloudFormation)
- Load testing report (k6 or Artillery results)
- 30-day post-launch support with 48-hour response time
What we ship in this practice.
Payment Processing API for Fintech Startup
Built a RESTful API for recurring billing and invoicing. The API reduced payment failures by 40% through idempotency and retry logic. Tech stack: Node.js, PostgreSQL, Stripe API.
Real-Time Fleet Tracking API for Logistics
Developed a WebSocket-based API for GPS location streaming. Delivery times improved by 15% due to live route optimization. Tech stack: Go, WebSockets, Redis, AWS IoT Core.
Patient Data Exchange API for Telemedicine
Created a FHIR-compliant REST API to integrate with existing EHR systems. Manual data entry errors dropped by 90%. Tech stack: Python, FastAPI, PostgreSQL, HL7 FHIR.
Product Catalog API for E-commerce Platform
Designed a GraphQL API for product search and personalized recommendations. The API increased conversion rates by 30% through faster load times. Tech stack: GraphQL, Elasticsearch, Node.js.
Internal API Platform for SaaS CRM
Built a microservices API gateway with Kong for service discovery and rate limiting. Internal team velocity increased by 50% for new features. Tech stack: Kong, Node.js, MongoDB, Docker.
Third-Party Integration API for Real Estate MLS
Developed a REST API to synchronize property listings across multiple MLS providers. Data now updates automatically every 15 minutes with 99.9% uptime. Tech stack: Go, PostgreSQL, RabbitMQ.
Why teams hire us.
Fixed price, not hourly
Every API project gets a fixed quote during the Roadmap phase (week 2). No surprise invoices or hourly billing.
99.9% uptime SLA
Your API runs on AWS/GCP with auto-scaling and multi-region failover. We guarantee 99.9% uptime with monitoring.
Security by default
We implement OAuth 2.0, JWT, rate limiting, and input validation from day one. Every project passes a security audit before launch.
You own the code
After the project, you get full ownership. Source code, documentation, and deployment scripts are all yours.
Senior engineers only
Our team consists of senior developers with 10+ years experience. No junior shuffling.
48-hour response time
Post-launch, we provide 30 days of support with guaranteed 48-hour response time for critical issues.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
