Professional API Development StudioAPI Development
We build production-grade APIs for web, mobile, and AI products. 200+ APIs shipped in 12 weeks or less.
IRPR is a professional API development studio that builds custom APIs using Node.js, Python, Go, and .NET. We design REST, GraphQL, and gRPC endpoints with OpenAPI 3.0 specs and automated testing via Postman and Jest.
Every API project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle compliance for HIPAA, PCI-DSS, and SOC 2, including audit logs, encryption at rest, and rate limiting.
CTOs hire us to replace legacy SOAP APIs with modern RESTful services. Product managers hire us to build the backend for their SaaS MVP. Data teams hire us to create ingestion pipelines for real-time analytics.
Types of software we ship.
REST API Development
Stateless JSON endpoints with JWT auth, rate limiting, and OpenAPI docs. Built with Express.js or FastAPI.
GraphQL API Development
Single endpoint with Apollo Server, resolver caching, and schema stitching. Supports subscriptions for real-time data.
gRPC API Development
High-performance binary APIs using Protocol Buffers. Ideal for microservices and internal service-to-service calls.
Webhook API Development
Event-driven endpoints that push data to Stripe, Slack, or custom URLs. Includes retry logic and idempotency keys.
Third-Party API Integration
Connect your app to Salesforce, HubSpot, Shopify, or QuickBooks. We handle OAuth 2.0 flows and data mapping.
API Gateway Development
Centralized gateway with Kong or AWS API Gateway. Manages auth, throttling, logging, and versioning across services.
Real-Time API Development
WebSocket and Server-Sent Events endpoints for live dashboards, chat, and notifications. Uses Socket.io or AWS AppSync.
Internal API Development
Private APIs for microservices communication. Includes service discovery, circuit breakers, and distributed tracing with Jaeger.
We build for every business type.
Healthcare
Fintech
Ecommerce
SaaS
Logistics
Why a Professional API Development Studio Matters
A poorly designed API costs you time, money, and developer trust.
IRPR has shipped 200+ APIs across 50 countries. Our APIs average 99.9% uptime and handle 10,000 requests per second. We use OpenAPI 3.0 for documentation and Postman collections for testing.
Every API includes rate limiting, JWT authentication, and structured error responses. We deploy on AWS ECS or Kubernetes with auto-scaling and CloudWatch monitoring. No black box. No surprises.
The Difference Between IRPR and a Generic Dev Shop
Most agencies deliver APIs that break under load. We don't.
Generic shops write endpoints without specs, skip load testing, and hand you a zip file. IRPR delivers a production-grade API with CI/CD, monitoring, and documentation.
We use OpenAPI 3.0, automated load testing with k6, and deploy on AWS with auto-scaling. Your team gets full source code, a running staging environment, and a 30-day warranty.
- No OpenAPI spec
- No load testing
- No CI/CD pipeline
- No monitoring or alerts
- No rate limiting
- No documentation
- OpenAPI 3.0 spec from day one
- k6 load testing at 10K RPS
- GitHub Actions CI/CD
- CloudWatch + Sentry monitoring
- Rate limiting + JWT auth
- Postman collection + Swagger UI
How We Build Your API in 12 Weeks
Our process is designed for speed and quality.
We start with a 2-week Roadmap phase where we define endpoints, data models, and auth flows. You get a fixed price and timeline before any code is written.
Then we build in 2-week sprints with demos every Friday. You see working endpoints, test them in Postman, and give feedback. No surprises.
What Ships With Every API Project
You own everything. No black boxes.
Every API project includes source code, infrastructure as code, and full documentation. You can deploy, modify, and scale without us.
We use Terraform for AWS infrastructure, GitHub Actions for CI/CD, and Sentry for error tracking. Your team gets admin access to all tools.
- Source code in your GitHub repo
- OpenAPI 3.0 specification
- Postman collection with test cases
- CI/CD pipeline on GitHub Actions
- Docker containers for local development
- Terraform scripts for AWS infrastructure
- Sentry error tracking
- CloudWatch dashboards and alerts
- Rate limiting and JWT auth
- 30-day warranty and support

Why teams hire us.
Fixed price, not hourly
Every API 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 averages 10+ years of experience. Every engineer has shipped at least 5 production APIs. No juniors, no offshore code mills.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliant APIs by default. Audit logs, encryption at rest, and access controls are part of every project.
You own the code
Full source code, infrastructure scripts, and documentation are yours. No licensing fees, no vendor lock-in. Deploy anywhere.
12-week delivery guarantee
We ship production-grade APIs in 8-12 weeks. 98% of our projects finish on time. If we miss the deadline, you get a discount.
Post-launch support
Every project includes 30 days of bug fixes and support. We also offer monthly retainers for maintenance, updates, and scaling.
