Premium Backend API Development StudioDevelopment Studio
We build high-performance APIs for your product. 8-12 week delivery with fixed pricing.
IRPR is a premium backend API development studio. We build APIs using Node.js, Python, Go, and frameworks like Express, FastAPI, and GraphQL.
We deliver production-ready APIs in 8-12 weeks with fixed pricing from $80K to $250K. Our APIs are built with security (OAuth2, JWT), monitoring (Datadog, Sentry), and CI/CD (GitHub Actions).
Founders who need to launch a SaaS MVP, CTOs scaling their platform, product managers integrating third-party services, and enterprise teams migrating to microservices hire us to build reliable APIs.
Types of software we ship.
REST API Development
Build standard RESTful APIs with OpenAPI specs, versioning, and rate limiting. Integrates with any frontend or third-party service.
GraphQL API Development
Build flexible GraphQL APIs with Apollo Server or Relay. Clients query exactly what they need, reducing over-fetching.
Microservices API Gateway
Design API gateways using Kong or AWS API Gateway. Route traffic, handle auth, and aggregate responses from multiple services.
Webhook API Development
Build webhook endpoints that deliver real-time events to your customers. Includes retry logic, signature verification, and logging.
Real-time API (WebSocket)
Build WebSocket APIs for live data streaming. Used for chat, notifications, live dashboards, and collaborative apps.
Internal API / B2B API
Build private APIs for your internal services or B2B partners. Includes API keys, usage plans, and detailed documentation.
Payment API Integration
Build APIs that integrate with Stripe, Square, or Braintree. Handle subscriptions, invoicing, and payment webhooks.
Data API / ETL API
Build APIs that expose data from databases or external sources. Includes caching, pagination, and aggregation for analytics.
We build for every business type.
SaaS and Platform Companies
Fintech and Payments
Healthcare and Life Sciences
Ecommerce and Retail
Enterprise and Internal Tools
Why a Premium Backend API Development Studio Matters
A poorly designed API costs you customers and developer hours.
We build APIs that are fast, secure, and documented from day one. Our APIs handle 10,000 requests per second with 99.9% uptime.
We use OpenAPI 3.0 for specification, automated tests with Postman/Newman, and deploy with Docker and Kubernetes. Every API ships with a developer portal and SDK examples.
How We Build Your API
We follow a proven process from idea to production.
Our Roadmap phase (week 2) defines endpoints, data models, and security requirements. We then build in 2-week sprints with continuous deployment.
You get a staging environment after 4 weeks. Full production release by week 8-12 with monitoring, logging, and error tracking.
- No API spec until late
- Poor documentation
- No rate limiting or auth
- No CI/CD pipeline
- No monitoring in place
- Cost overruns due to hourly billing
- OpenAPI 3.0 spec delivered week 2
- Auto-generated docs with Swagger UI
- OAuth2, JWT, API keys built-in
- GitHub Actions CI/CD from day one
- Datadog monitoring and Sentry error tracking
- Fixed price, no surprises
Our API Development Process
We break down the build into four clear phases.
Phase 1: Discovery and specification. We map your business logic to endpoints, data models, and integrations.
Phase 2: Core API build. We implement endpoints, authentication, and testing. You see progress every 2 weeks.
What Ships with Your API
You own everything we build.
Every project includes source code in your GitHub repo, CI/CD pipeline, Docker containers, and a deployment guide.
We also provide Postman collections, API documentation (Swagger/Redoc), and a monitoring dashboard.
- Source code in your private GitHub repo
- OpenAPI 3.0 specification
- CI/CD pipeline with GitHub Actions
- Dockerized API service
- Postman collection with test examples
- Swagger UI documentation
- Sentry error tracking configured
- Datadog monitoring dashboard
- Deployment guide for AWS/GCP/Azure
- API key management system
What we ship in this practice.
SaaS Subscription API
Built a REST API for a subscription billing platform. Reduced failed payments by 30% using Stripe webhooks and idempotency keys. Tech: Node.js, Express, PostgreSQL, Stripe.
Real-Time Chat API
Built a WebSocket API for a customer support chat app. Handled 50,000 concurrent connections with sub-100ms latency. Tech: Node.js, Socket.io, Redis, AWS ECS.
Payment Gateway Integration API
Built a unified payment API that integrates Stripe, PayPal, and Square. Saved the client 40 hours of development per month. Tech: Python, FastAPI, Stripe SDK, PostgreSQL.
Healthcare Data Exchange API
Built a FHIR-compliant API for a telemedicine platform. Enabled secure data exchange with 10+ EHR systems. Tech: Go, FHIR, OAuth2, AWS Lambda.
Ecommerce Order Management API
Built a REST API for a multi-channel retailer. Automated order syncing across Shopify, Amazon, and WooCommerce. Reduced manual entry by 15 hours/week. Tech: Node.js, Express, MongoDB, RabbitMQ.
Internal Microservices Gateway
Built an API gateway for a fintech company. Aggregated 12 microservices into a single endpoint with rate limiting and caching. Reduced latency by 60%. Tech: Kong, Go, Redis, Kubernetes.
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.
Senior Engineers Only
Our team consists of senior engineers with 10+ years of experience. No junior developers, no offshore outsourcing, no handoffs.
8-12 Week Delivery
We ship production-ready APIs in 8-12 weeks. Our sprint-based process ensures you see working code every 2 weeks.
Full Ownership
You own the source code, documentation, and infrastructure. No lock-in, no licensing fees, no ongoing royalties.
Security by Default
Every API includes OAuth2/JWT authentication, rate limiting, input validation, and encrypted data storage. We follow OWASP guidelines.
Post-Launch Support
We provide 30 days of post-launch support for bug fixes and minor changes. Extended maintenance contracts available at fixed monthly rates.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
