Professional Backend API Development DevelopersBackend API
We build APIs that scale. 200+ products shipped in 8-12 weeks with fixed pricing.
IRPR is a software development studio that provides professional backend API development developers. We use Node.js, Python, Go, and Java to build REST, GraphQL, and gRPC APIs. Every engineer has 10+ years of experience.
We ship fully functional APIs in 8-12 weeks. Pricing is fixed from the Roadmap phase and ranges from $80K to $250K. All APIs meet OWASP security standards and HIPAA or PCI-DSS compliance if needed.
CTOs hire us when they need an API team that delivers on time. Product managers hire us to build integrations without scope creep. Startup founders hire us to launch their platform with production-ready backend infrastructure.
Types of software we ship.
REST API
Stateless HTTP APIs for CRUD operations. Used with Express.js, Django, or FastAPI. Includes Swagger/OpenAPI docs.
GraphQL API
Flexible query language for efficient data fetching. Built with Apollo or Hasura. Reduces over-fetching by 40%.
Microservices API
Decoupled services that communicate via message queues. Uses RabbitMQ or Kafka. Each service scales independently.
Third-party API integration
Connect your app to Stripe, HubSpot, Salesforce, or Shopify. We handle OAuth, rate limits, and error handling.
Webhook system
Real-time event notifications sent to external URLs. Built with AWS EventBridge or SendGrid. 99.9% delivery guarantee.
API gateway
Single entry point for multiple microservices. Configured with Kong or AWS API Gateway. Handles auth, throttling, and routing.
Real-time API (WebSocket)
Persistent connections for live updates. Uses Socket.io or WebSocket API. Used for chat, notifications, and live dashboards.
Internal RPC API
High-performance backend-to-backend communication. Implements gRPC or Thrift. 10x faster than REST for internal services.
We build for every business type.
Ecommerce
Fintech
Healthcare
SaaS
Logistics
Why professional backend API development developers matter
A poorly built API costs 3x more to fix after launch. We build it right the first time.
Professional backend API development developers are the difference between an MVP that survives traffic spikes and one that crashes. We use Node.js, Python Go, and Java with PostgreSQL or MongoDB. Every API includes rate limiting, caching, and error logs.
Our team ships an average of 15 endpoints per week during development. We test at 10,000 requests per second on day one. Production APIs run on AWS or GCP with auto-scaling and 99.9% uptime.
The difference between generic shops and professional backend API development developers
Not all developers are equal. Here is what we do differently.
Generic dev shops assign junior engineers to your API. They bill hourly and change scope every sprint. Documentation is an afterthought. You get a fragile API that fails at peak load.
IRPR assigns a senior engineer with 10+ years of backend experience. We give you a fixed price in week 2. Every API ships with auto-generated Swagger docs, CI/CD pipelines, and load tests.
- Junior developers with 1-2 years of experience
- Hourly billing with 40% overrun average
- No API documentation until final week
- Manual deployments with no staging environment
- No load testing under 100 concurrent users
- Code ownership unclear
- Senior engineers with 10+ years experience
- Fixed price from Roadmap, no surprises
- Swagger/OpenAPI docs generated at each sprint
- CI/CD pipeline with GitHub Actions and staging
- Load tests at 10,000 concurrent users
- Full source code ownership from day one
How IRPR builds your backend API in 4 phases
We use the Idea-Roadmap-Product-Release framework to ship fast without cutting corners.
Phase 1: Idea. We map your business logic to API endpoints. No coding yet. We identify integrations and data models in 1 week.
Phase 2: Roadmap. We write a detailed specification with endpoints, auth, and schema. You get a fixed price and timeline. 2 weeks.
What ships with every professional backend API
You get a production-ready system, not just code.
Every API project includes infrastructure, monitoring, and documentation. We do not hand over a zip file. You get a git repository with deployment scripts and runbooks.
- Source code in your private GitHub or GitLab repo
- CI/CD pipeline using GitHub Actions or GitLab CI
- Auto generated Swagger/OpenAPI 3.0 documentation
- Docker container with docker compose for local dev
- Cloud infrastructure code (Terraform or Pulumi)
- Sentry error tracking and Datadog monitoring
- Load test suite using k6 or Locust
- Unit and integration tests with 85%+ coverage
- Postman collection for manual testing
- Runbook with deployment and rollback steps
What we ship in this practice.
Payment processing API for a fintech startup
Built a REST API that handles 1,200 transactions per second with Stripe and Plaid. Reduced manual reconciliation from 5 hours to 10 minutes. Tech stack: Python, FastAPI, PostgreSQL, Stripe API.
Patient data exchange API for a healthcare provider
Built a FHIR compliant API connecting 3 EHR systems. Eliminated 20 hours of manual data entry per week. Tech stack: Java, Spring Boot, HL7 FHIR, AWS, HIPAA compliant.
Product catalog API for an ecommerce brand
Built a GraphQL API serving 500,000 products with faceted search. Cut page load time from 4 seconds to 0.8 seconds. Tech stack: Node.js, Apollo, Elasticsearch, Redis.
Real-time tracking API for a logistics company
Built a WebSocket API that streams GPS coordinates from 2,000 trucks every 5 seconds. Dispatchers can now reroute shipments in under 1 minute. Tech stack: Go, WebSocket, Redis Pub/Sub, AWS IoT.
User management API for a B2B SaaS platform
Built a multi-tenant REST API that supports 10,000 organizations with role based access control. Onboarding time dropped from 3 days to 1 hour. Tech stack: Ruby on Rails, PostgreSQL, JWT, Okta.
Content syndication API for a media company
Built a REST API that distributes articles to 15 publishing partners automatically. Reduced publishing time from 2 hours to 12 minutes. Tech stack: Python, FastAPI, PostgreSQL, RabbitMQ.
Why teams hire us.
Fixed price from week 2
Every project gets a fixed quote during the Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges. 98% of our projects finish within the quoted price.
Senior engineers only
We do not hire juniors. Every professional backend API development developer on our team has 10+ years of experience. You get a lead engineer who can make architectural decisions without asking a manager.
Full code ownership
The source code, infrastructure configs, and documentation belong to you. IRPR does not claim any IP. You can deploy with any team after we finish.
Compliance ready from day one
We have built APIs for HIPAA, PCI-DSS, SOC 2, and FERPA compliance. We include audit logs, encryption at rest, and role based access in every project.
8-12 week delivery guarantee
We ship production ready APIs in 8-12 weeks. If we miss the deadline, we work overtime at no extra cost. Our on time delivery rate is 98%.
Post-launch monitoring and support
We monitor your API for 30 days after launch. You get a runbook, access to our Sentry and Datadog dashboards, and a 1 hour SLA for critical issues.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
