Premium Backend API Development DevelopersAPI Development
We build secure, high-performance APIs for your product. Get a fixed-price MVP in 8-12 weeks.
IRPR builds premium backend API development for startups and enterprises using Node.js, TypeScript, PostgreSQL, and event-driven architecture. We design RESTful and GraphQL APIs with rate limiting, caching, and comprehensive documentation.
Our developers ship production-ready APIs in 8-12 weeks with fixed pricing from $80K-$250K. Every API passes load testing and includes CI/CD pipelines, Sentry monitoring, and Docker containerization.
Who hires us: CTOs launching a SaaS need a scalable API backend. Founders building fintech platforms require PCI-DSS compliant APIs. Product leaders at healthcare companies need HIPAA-eligible API infrastructure. Engineering managers at ecommerce brands need high-throughput APIs for order processing.
Types of software we ship.
REST API Development
Build stateless APIs with JSON responses and JWT authentication. Uses Express.js and Swagger docs.
GraphQL API Development
Design flexible queries and mutations with Apollo Server. Reduces over-fetching by 40% on mobile apps.
Microservices API Gateway

Why premium backend API development matters
Your API is the foundation for every integration, user action, and data flow.
A well-built API reduces development time for frontend teams and ensures third-party integrations work without issues. IRPR has shipped over 200 APIs that handle millions of requests per day with 99.9% uptime.
We focus on documentation, load testing, and security from day one. Every premium backend API development project includes auto-generated OpenAPI specs and k6 load tests that verify sub-200ms response times.
The difference between a generic dev shop and IRPR
Most API projects fail due to scope creep, poor documentation, or security holes.
Generic dev shops often start coding without a spec, leading to endless revisions and budget overruns. They skip load testing and deliver APIs that crash under real traffic.
IRPR follows a structured process: we design the API spec first, get your approval, then build with TypeScript and Postgres. Every API is load tested to handle 10,000 requests per second before deployment.
- No fixed pricing, hourly billing leads to cost overruns
- No API documentation beyond code comments
- No load testing before launch
- Single tech stack regardless of use case
- No post-launch monitoring
- Code ownership often unclear
- Fixed price from Roadmap phase (week 2)
- Auto-generated OpenAPI docs with Swagger UI
- k6 load tests to 10K req/s
- Multi-stack: Node, Go, Python, Rust
- Sentry + Datadog monitoring from day one
- Full code ownership, no licensing fees
How we build your premium API in 4 phases
Our process ensures your API is correct, fast, and documented.
We start with an API design phase where you review every endpoint and data model before any code is written. This prevents costly rework.
After you approve the spec, we build in two-week sprints with daily standups and weekly demos. Load testing runs continuously from week 4 onward.
What ships with your API by default
Every API project includes these deliverables, no negotiation.
Everything listed below is included in the fixed price. No add-ons, no surprises.
You own every file, every script, and every dashboard. Your team can start extending the API the day after launch.
- Source code in your private GitHub repo
- CI/CD pipeline using GitHub Actions
- Docker containers for local dev
- API documentation via Swagger UI
- Postman collection for testing
- Sentry error monitoring
- Datadog performance metrics
- Terraform scripts for infrastructure
- Load test reports (k6 output)
- Auth system with JWT and OAuth2
What we ship in this practice.
Payment Processing API for Fintech Startup
Built a PCI-DSS compliant payment API handling 10,000 transactions per day. Integrated with Stripe Connect for sub-merchant management. Tech: Go, PostgreSQL, Stripe API.
Telehealth Patient Data API
Developed a HIPAA-eligible REST API for a telemedicine platform. Reduced patient data retrieval time by 60%. Tech: Node.js, MongoDB, AWS KMS.
Ecommerce Product Catalog API
Built a GraphQL API for a multi-tenant ecommerce platform. Serves 500+ products per second with Redis caching. Tech: Apollo Server, Elasticsearch, Redis.
Real-Time Analytics Dashboard API
Created a WebSocket API that streams user events to a live dashboard. Handles 1M events per hour with less than 50ms latency. Tech: Socket.io, Kafka, Postgres.
SaaS Subscription Management API
Built a CRUD API for managing subscriptions, billing cycles, and usage metering. Achieved 99.99% uptime over 6 months. Tech: Node.js, Stripe, MongoDB.
HR Platform Integration API
Developed a set of REST endpoints to sync employee data between HR tools and payroll systems. Eliminated 15 hours of manual data entry per week. Tech: Python Flask, Plaid, QuickBooks API.
Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges.
12-week MVP guarantee
We deliver a production-ready API in 8-12 weeks. Over 200 projects shipped with 98% on-time rate.
Security-first architecture
Every API includes rate limiting, input validation, JWT authentication, and encryption at rest. We pass HIPAA and PCI-DSS audits.
Full ownership of code
You own every line of code, the Docker images, and the CI/CD pipeline. No lock-in, no licensing fees.
Multi-stack expertise
Our engineers work in Node.js, Go, Python, and Rust. We choose the best stack for your throughput needs.
Post-launch monitoring included
We set up Sentry error tracking, Datadog performance dashboards, and automated alerts. You know when something breaks before users do.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
