Professional Backend API Development StudioAPI Development
We build production-grade APIs that handle millions of requests. Fixed price, 8-12 week delivery, full code ownership.
IRPR is a professional backend API development studio. We build APIs using Node.js, Python, Go, and Rust with PostgreSQL, Redis, and Kafka for data handling. Every API is designed for scale, security, and maintainability.
We ship a production-ready API in 8-12 weeks with a fixed price of $80K-$250K. Our APIs are HIPAA, PCI-DSS, and SOC 2 compliant. You get full source code, CI/CD pipelines, and 99.9% uptime SLAs.
Founders hire us to build the backend for their SaaS MVP. CTOs hire us to replace legacy APIs with modern microservices. Product managers hire us to integrate third-party APIs like Stripe, Salesforce, or Twilio.
Types of software we ship.
REST API Development
Stateless, cacheable APIs using Express.js or FastAPI. Ideal for web and mobile apps with clear resource endpoints.
GraphQL API Development
Flexible query language APIs using Apollo Server or Hasura. Clients fetch exactly the data they need.
Microservices API Development
Decoupled services communicating via gRPC or message queues. Each service scales independently.
Webhook API Development
Event-driven APIs that push data to your systems in real time. Built with Stripe or Twilio webhooks.
Third-Party API Integration
Connect your app to Salesforce, HubSpot, QuickBooks, or any external API. Handles auth, rate limits, and retries.
Real-Time API Development
WebSocket or Server-Sent Events APIs for live data. Used for chat, notifications, and live dashboards.
Internal API Development
Private APIs for your team's microservices or frontend. Documented with OpenAPI and secured with OAuth 2.0.
API Gateway Development
Single entry point for multiple backend services. Handles authentication, rate limiting, and logging with Kong or AWS API Gateway.
We build for every business type.
SaaS companies
Fintech companies
Healthcare companies

Why You Need a Professional Backend API Development Studio
Your API is the backbone of your product. A poorly built API costs you time, money, and customers.
IRPR has shipped over 200 APIs for clients in 50+ countries. Our APIs handle millions of requests per day with 99.9% uptime. We use Node.js, Python, Go, and Rust to match your performance needs.
Every API we build includes automated tests, CI/CD pipelines, and OpenAPI documentation. You get full ownership of the code and infrastructure. No black boxes, no vendor lock-in.
The Difference Between IRPR and Generic Dev Shops
Most agencies bill hourly and deliver late. IRPR works differently.
We give you a fixed price after a 2-week Roadmap phase. No hourly billing, no surprise invoices. You know the cost before we write a line of code.
Our senior engineers have 10+ years of experience each. They build APIs that are secure, scalable, and documented. You get a production-ready API in 8-12 weeks.
- Hourly billing with no cap
- Junior developers learning on your project
- No compliance knowledge (HIPAA, PCI, SOC 2)
- No CI/CD or automated testing
- No documentation or handover
- Code ownership unclear
- Fixed price after Roadmap phase
- Senior engineers with 10+ years experience
- HIPAA, PCI-DSS, SOC 2 compliant by default
- CI/CD pipeline with GitHub Actions
- OpenAPI documentation and full handover
- You own 100% of the code
Our API Development Process
We follow a 4-phase process to deliver your API on time and on budget.
Phase 1 is the Idea phase where we understand your requirements and define the API scope. Phase 2 is the Roadmap phase where we create a detailed plan and fixed price quote.
Phase 3 is the Product phase where our engineers build the API with daily commits and weekly demos. Phase 4 is the Release phase where we deploy to production and hand over all code and documentation.
What Ships With Every API
Every API project includes these deliverables by default.
You get more than just code. We ship a complete production-ready system with monitoring, documentation, and infrastructure as code.
All deliverables are handed over in your own GitHub repository. You can deploy anywhere: AWS, GCP, Azure, or your own servers.
- Source code in your GitHub repository
- CI/CD pipeline with GitHub Actions
- Automated test suite with 90%+ coverage
- OpenAPI 3.0 documentation
- Docker containers for local development
- Infrastructure as code (Terraform or Pulumi)
- Sentry error tracking and Datadog monitoring
- Rate limiting and authentication (JWT or OAuth 2.0)
- Database migrations and seed scripts
- Postman collection for manual testing
What we ship in this practice.
SaaS Subscription API
Built a multi-tenant API for a B2B SaaS platform handling 50,000 users. Used Node.js, PostgreSQL, and Stripe for billing. Reduced time to market by 4 months.
Payment Processing API
Developed a PCI-DSS compliant payment API for a fintech startup. Integrated with Stripe and Plaid. Processed $2M in transactions in the first month.
Patient Data API
Created a HIPAA-compliant API for a telehealth platform. Used Python, FastAPI, and FHIR standards. Handled 10,000 patient records securely.
Ecommerce Inventory API
Built a real-time inventory sync API for a multi-channel retailer. Integrated with Shopify, Amazon, and their warehouse system. Reduced stockouts by 30%.
Real Estate MLS API
Developed an API to aggregate MLS listings from 5 different sources. Used Go, PostgreSQL, and Redis for caching. Reduced listing update time from 24 hours to 5 minutes.
Learning Management API
Built a FERPA-compliant API for an edtech platform. Used Node.js, MongoDB, and AWS S3 for content storage. Supported 100,000 concurrent students.
Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote after the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges.
Senior engineers only
Our team has an average of 12 years of experience. No junior developers learning on your project. Every engineer has shipped production APIs before.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliant APIs by default. We handle audit logging, encryption, and access controls so you don't have to.
Full code ownership
You own 100% of the code and infrastructure. We hand over everything: source code, CI/CD pipelines, documentation, and deployment scripts.
8-12 week delivery
We ship production-ready APIs in 8-12 weeks. Our process is optimized for speed without sacrificing quality. 98% of our projects ship on time.
Post-launch support
We provide 30 days of post-launch support for every project. We fix bugs, answer questions, and help your team take over the codebase.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
