IRPR builds backend APIs using Node.js, Python, and Go, with PostgreSQL, Redis, and Docker for containerization. We design RESTful and GraphQL APIs that handle millions of requests per day.
Every API ships in 8-12 weeks with a fixed price of $80K-$250K. We support compliance standards like HIPAA, PCI-DSS, and SOC 2, and include load testing, documentation, and monitoring.
We work with CTOs modernizing legacy systems, startup founders launching SaaS backends, enterprise architects building microservices, and product managers scaling API-first platforms.
Types of software we ship.
REST API Development
Build stateless REST APIs with JSON responses, versioning, and rate limiting. Uses Express.js and Swagger for documentation.
GraphQL API Development
Develop flexible GraphQL APIs with Apollo Server, resolver patterns, and data loaders. Reduces over-fetching compared to REST.
Microservices API Development
Design decoupled microservices communicating via gRPC or message queues. Uses Docker, Kubernetes, and NATS.
Real-Time API Development
Build WebSocket and SSE APIs for live data streaming. Uses Socket.io, Redis Pub/Sub, and PostgreSQL LISTEN/NOTIFY.
Third-Party API Integration
Integrate Stripe, Twilio, Salesforce, or custom APIs with error handling and retry logic. Uses axios and circuit breakers.
API Gateway Development
Deploy API gateways with rate limiting, authentication, and routing. Uses Kong, NGINX, or AWS API Gateway.
API Security & Authentication
Implement OAuth 2.0, JWT, API keys, and role-based access control. Uses Auth0, Okta, or custom middleware.
API Documentation & Testing
Generate interactive docs with Swagger/OpenAPI and run automated tests with Postman or Supertest. Includes CI/CD integration.
We build for every business type.

Why Top Backend API Development Developers Choose IRPR
Our track record speaks for itself: 200+ products shipped, 50+ countries, and 98% on-time delivery.
We have built APIs for startups and enterprises across healthcare, fintech, ecommerce, and more. Every API is designed with scalability, security, and maintainability in mind.
Our developers are senior engineers with 10+ years of experience. We use Node.js, Python, Go, and Rust to build APIs that handle 10,000+ requests per second.
The Difference Between Generic Dev Shops and Top Backend API Development Developers
Not all API developers deliver the same quality. Here is what sets IRPR apart.
Generic dev shops often use junior developers, unclear requirements, and hourly billing. They deliver late, over budget, and with technical debt.
IRPR assigns senior engineers only, provides a fixed price after a 2-week Roadmap phase, and ships in 8-12 weeks. Every API comes with documentation, tests, and CI/CD.
- Junior developers with 0-3 years experience
- Hourly billing with no cap
- No compliance expertise (HIPAA, PCI)
- Vague requirements leading to scope creep
- No automated testing or CI/CD
- Deliverables often 3-6 months late
- Senior engineers with 10+ years experience
- Fixed price after Roadmap phase
- HIPAA, PCI-DSS, SOC 2 compliance built-in
- Clear spec in 2-week Roadmap
- Automated testing, CI/CD, monitoring included
- 8-12 week delivery, 98% on-time
Our Process for Building Top Backend API Development
We follow a proven 5-step process to ship your API on time and on budget.
Every project starts with a 2-week Roadmap phase where we define the API contract, data model, and endpoints. You get a fixed price and timeline before development begins.
Then we build iteratively, deploying to staging every 2 weeks. You see progress and give feedback. After final testing, we deploy to production and hand over full ownership.
What Ships When You Hire Top Backend API Development Developers

- API documentation (Swagger/OpenAPI)
- Load testing report (k6 or Artillery)
- Monitoring and alerting (Datadog, Sentry)
- Dockerized development environment
- Postman collection for manual testing
- Deployment playbook and runbook
- 1-year warranty on code quality
