Experienced Backend API Development StudioBackend API
We build production-grade backend APIs for SaaS platforms, mobile apps, and enterprise systems. 200+ products shipped in 12 weeks or less with fixed pricing.
IRPR is an experienced backend API development studio. We build APIs using Node.js, Python, Go, and Rust with PostgreSQL, Redis, and Kafka. Every API is designed for scale from day one.
A typical backend API project ships in 12 to 14 weeks. Fixed pricing starts at $80K and goes to $250K depending on complexity. All APIs meet compliance standards like HIPAA, PCI-DSS, and SOC 2.
We work with CTOs launching a new SaaS product, product managers who need a mobile app backend, and engineering leads migrating from monoliths to microservices. Each client gets senior engineers only, no juniors.
Types of software we ship.
REST API Development
Build stateless REST APIs with Node.js or Python. Integrates with Stripe, Twilio, and Auth0. Designed for mobile and web clients.
GraphQL API Development
Create flexible GraphQL APIs using Apollo Server or Hasura. Clients query exactly what they need, reducing payload size by 40%.
Microservices Architecture
Decompose monoliths into independent microservices. Uses Docker, Kubernetes, and gRPC for inter-service communication.
Real-Time API Development
Build WebSocket and Server-Sent Events APIs for live updates. Used for chat, notifications, and live dashboards with Socket.io.
Third-Party API Integration
Connect your system to Salesforce, HubSpot, Shopify, and 50+ other platforms. Custom connectors with retry logic and rate limiting.
API Gateway Development
Deploy an API gateway with Kong or AWS API Gateway. Handles authentication, rate limiting, and request routing for multiple services.
Event-Driven API Architecture
Implement event-driven systems using Apache Kafka or RabbitMQ. Enables async processing and decoupled services for high throughput.

Why Hire an Experienced Backend API Development Studio
Building a production-grade backend API requires deep knowledge of distributed systems, security, and performance tuning.
IRPR has shipped over 200 backend APIs since 2016. Our senior engineers have built systems handling 10 million requests per day. We use Node.js, Python, Go, and Rust depending on your use case. Every API is deployed with CI/CD on GitHub Actions and monitored with Datadog.
We follow a fixed-price model. After a 2-week Roadmap phase, you get a fixed quote for the entire build. No hourly billing, no surprises. Average API project timeline is 12 to 14 weeks. We handle everything from database design to deployment.
IRPR vs Generic Development Shops
Not all backend API shops deliver the same quality. Here is how IRPR stands apart from generic agencies.
Generic shops often assign junior developers to your project. They use hourly billing that leads to scope creep and budget overruns. Their APIs lack proper documentation, monitoring, and security reviews. You end up with code that does not scale and a team that disappears after launch.
IRPR assigns only senior engineers with 10+ years of experience. We give you a fixed price after a 2-week Roadmap phase. Every API ships with OpenAPI specs, automated tests, CI/CD pipelines, and Datadog monitoring. We stay on for 30 days post-launch to ensure stability.
- Junior developers assigned to your project
- Hourly billing with no cap
- No API documentation generated
- Manual deployment with no CI/CD
- No load testing or performance benchmarks
- Team disbands after delivery
- Senior engineers only, 10+ years experience
- Fixed price after 2-week Roadmap
- OpenAPI 3.0 specs shipped with every API
- GitHub Actions CI/CD with automated tests
- Load testing with k6, 10K concurrent users
- 30-day post-launch support included
Our Backend API Development Process
We follow a structured 4-phase process to deliver your backend API on time and on budget.
Every project starts with a 2-week Roadmap phase. We map out your API endpoints, data model, authentication, and deployment strategy. You get a detailed document and a fixed price for the build.
Then we build your API in 8 to 12 weeks. We work in 2-week sprints with daily standups and weekly demos. You see progress every week. After launch, we monitor the API for 30 days and fix any issues.
What Ships With Every Backend API
Every API we build ships with a complete set of production-grade deliverables. No shortcuts.
You get more than just code. Every API includes documentation, tests, deployment scripts, and monitoring. Your team can take over immediately without relying on us.
- Source code in your GitHub repo
- OpenAPI 3.0 specification
- CI/CD pipeline on GitHub Actions
- Automated unit and integration tests (90%+ coverage)
- Database schema migrations (PostgreSQL or MySQL)
- Docker containers and docker-compose for local dev
- Kubernetes manifests for production deployment
- Datadog monitoring dashboard and alerts
- Load test results with k6 (10K concurrent users)
- Post-launch 30-day support and bug fixes
