Leading Backend API Development DevelopersAPI Development
We build production-grade backend APIs that scale. Your MVP ships in 8-12 weeks with full source code ownership.
IRPR builds backend APIs for web apps, mobile apps, and SaaS platforms. We use Node.js, Python, Go, PostgreSQL, Redis, and AWS to deliver fast, secure APIs that handle millions of requests per day.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle authentication, rate limiting, database design, CI/CD, and monitoring. Compliance options include HIPAA, PCI-DSS, and SOC 2.
We are hired by CTOs who need a reliable backend team, product managers who are stuck with slow API development, and startup founders who want a production-ready API without hiring in-house engineers.
Types of software we ship.
REST API development
Stateless APIs with OpenAPI specs. Built with Express, FastAPI, or Go Gin. Support for versioning and pagination.
GraphQL API development
Flexible data queries with Apollo Server or Hasura. Reduces overfetching and speeds up frontend development.
Microservices API
Decoupled services communicating via gRPC or message queues. Each service deploys independently on Kubernetes.
Real-time API (WebSocket)
Low-latency WebSocket APIs for chat, live updates, and collaborative tools. Uses Socket.IO or AWS API Gateway WebSockets.
Third-party API integration
Connect your app to Stripe, Salesforce, HubSpot, or Twilio. Handles rate limits, webhooks, and error retries.
Data pipeline API
ETL APIs that ingest, transform, and serve large datasets. Built with Apache Kafka, Airflow, and Redis.
Backend for mobile apps
APIs optimized for mobile clients. Supports offline sync, push notifications, and image upload via S3.
Serverless API
Event-driven APIs using AWS Lambda and API Gateway. Auto-scales to zero during low traffic. Pay-per-request cost model.
We build for every business type.
Healthcare SaaS
Fintech startups
Ecommerce platforms
Logistics and supply chain
Media and streaming
Why Leading Backend API Development Developers Choose IRPR
Our team has shipped over 200 API products across 50 countries, delivering on time 98% of the time.
We write clean, tested code with CI/CD pipelines on GitHub Actions. Every API ships with Swagger documentation, rate limiting, and error monitoring via Sentry. Our engineers have built systems that handle 10,000 requests per second for enterprise clients.
We fix the price after the Roadmap phase. No hourly billing, no scope creep. Typical projects run 8-12 weeks and cost $80K-$250K depending on complexity. Startups get a production-ready API, not a prototype.
The Difference Between Generic Shops and Leading Backend API Development Developers
Most dev shops overpromise and underdeliver. IRPR ships working APIs with full documentation and monitoring.
Generic shops often use junior engineers, skip automated tests, and deliver undocumented code. They bill by the hour and change scope mid-project. You end up with a broken API and a budget overrun.
IRPR assigns senior engineers only. We write unit tests, integration tests, and load tests. Every API gets a CI/CD pipeline, Docker containerization, and Sentry error tracking. You own the source code and can deploy anywhere.
- Junior engineers, high turnover
- No automated tests
- Undocumented endpoints
- Hourly billing, scope creep
- No CI/CD pipeline
- No monitoring or alerts
- Senior engineers only (10+ years)
- 100% test coverage on critical paths
- Swagger/OpenAPI docs shipped
- Fixed price after Roadmap phase
- GitHub Actions CI/CD, Docker, AWS
- Sentry error tracking, PagerDuty alerts
How We Build Your Leading Backend API
Four phases. No surprises. You get a working API that meets compliance requirements.
We start with a 2-week Roadmap phase to define endpoints, data models, and integrations. Then we build the API in parallel sprints, delivering a working version every 2 weeks. After testing and deployment, we hand over full ownership.
Your team gets a deployable API with automated infrastructure, monitoring, and documentation. We also provide a 30-day post-launch support window to handle any issues.
What Ships with Your Backend API
You get a production-ready API with everything needed to run it in the real world.
We don't just write code. We give you the infrastructure to run the API, monitor its health, and debug issues. Your team can take over immediately because everything is documented.
All code lives in your repository from day one. We use GitHub Actions for CI/CD and Terraform for infrastructure as code. You own everything, no lock-in.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions and Docker
- Swagger/OpenAPI documentation
- Postman collection for all endpoints
- Database schema migration scripts
- Sentry error monitoring and alerts
- Rate limiting and authentication middleware
- Load test results from k6
- Deployment guide and runbook
- 30-day post-launch support
