Leading API Development TeamDevelopment Team
We build secure, scalable APIs that ship in 8-12 weeks. Fixed price. No hourly billing.
IRPR is a leading API development team that builds production-grade APIs using Node.js, Go, Python, and Postgres. We design REST and GraphQL endpoints with OpenAPI specs, JWT auth, and rate limiting out of the box.
Every API ships in 8-12 weeks with a fixed price starting at $80K. We handle PCI-DSS for fintech, HIPAA for healthcare, and SOC 2 for SaaS. Our team has delivered APIs for 200+ products across 50+ countries.
CTOs hire us to replace their slow internal teams. Startup founders hire us to build their first API before funding. Enterprise architects hire us to modernize legacy SOAP or monolithic backends into microservices.
Types of software we ship.
REST API Development
Build stateless RESTful endpoints with JSON responses, versioning, and caching. Uses Express, Fastify, or Django REST Framework.
GraphQL API Development
Create flexible GraphQL schemas with Apollo Server or Hasura. Supports real-time subscriptions and batch queries.
Microservices API Gateway
Design a unified gateway with Kong or NGINX to route traffic, handle auth, and enforce rate limits across 10+ services.
Payment API Integration
Integrate Stripe, Braintree, or Square APIs for checkout flows, subscription billing, and payout reconciliation.
Third-Party API Wrapper
Build a reliable wrapper around external APIs like Salesforce, HubSpot, or Twilio with retry logic and caching.
Internal API for Microservices
Develop gRPC or RabbitMQ-based internal APIs for service-to-service communication with low latency.
API Documentation Portal
Generate interactive docs using Swagger UI or Redoc with OpenAPI 3.0 specs, code samples, and test endpoints.
Webhook and Event API
Build event-driven APIs with webhook delivery using Stripe-style signatures, idempotency keys, and retry queues.
We build for every business type.
Fintech
Healthcare
SaaS
Ecommerce
Logistics
Why You Need a Leading API Development Team
A poorly designed API breaks integrations, frustrates developers, and costs you customers.
IRPR has built APIs for 200+ products. We use OpenAPI 3.0 specs to define every endpoint before writing code. This gives your frontend and mobile teams a single source of truth. Our APIs include pagination, error codes, and rate limiting by default.
We also handle API security. Every endpoint gets JWT or OAuth 2.0 auth, input validation with Zod or Pydantic, and automatic DDoS protection via Cloudflare. We run load tests with k6 to verify 10,000 requests per second before launch.
IRPR vs. Generic Dev Shops
Most agencies treat APIs as an afterthought. IRPR treats them as the product.
Generic shops write endpoints without specs, skip error handling, and deliver spaghetti code. IRPR follows a strict process: spec first, build second, test third. Every API ships with Postman collections, unit tests at 90%+ coverage, and a CI/CD pipeline.
We also provide a 3-month warranty on all APIs. If a bug appears in production, we fix it within 24 hours. No extra charge.

Our API Development Process
We ship APIs in 4 phases over 8-12 weeks.
Phase 1 is the Roadmap. In week 1-2, we define endpoints, data models, and auth flows. You get a fixed price quote. Phase 2 is building the API with Node.js, Go, or Python. We use Postgres or MongoDB for storage and Redis for caching.
Phase 3 is testing and documentation. We run 1000+ automated tests, generate OpenAPI docs, and deploy to staging. Phase 4 is production release with monitoring via Datadog and Sentry.
What Ships with Every API
Every API project includes these deliverables by default.
- OpenAPI 3.0 spec file
- Source code in your GitHub repo
- CI/CD pipeline with GitHub Actions
- Postman collection with 50+ test requests
- Unit tests with 90%+ coverage
- Load test results from k6
- Deployment to AWS ECS or Kubernetes
- Sentry error tracking
- Datadog monitoring dashboard
- 3-month warranty with 24hr bug fixes
What we ship in this practice.
Payment Processing API for Fintech Startup
Built a Stripe-integrated API that handles 5000 transactions per minute with idempotency keys and webhook retries. Reduced failed payments by 30%. Tech stack: Node.js, Express, Postgres, Stripe API.

Designed a FHIR-compliant API for a telemedicine platform. Encrypted all PHI at rest and in transit. Passed HIPAA audit on first try. Tech stack: Python, FastAPI, Postgres, Auth0.
Real-Time Inventory API for Ecommerce
Built a WebSocket-based inventory API that syncs stock levels across 3 warehouses in under 200ms. Cut overselling by 99%. Tech stack: Go, Redis, GraphQL, RabbitMQ.
Multi-Tenant SaaS Billing API
Created a subscription management API with Stripe Billing, usage metering, and proration. Supported 1000+ tenants on day one. Tech stack: Node.js, Postgres, Stripe, Redis.
MLS Data API for Real Estate Platform
Aggregated listings from 50+ MLS feeds into a single REST API with geospatial search. Reduced data latency from 24 hours to 5 minutes. Tech stack: Python, FastAPI, Elasticsearch, AWS Lambda.
Logistics Tracking API for Delivery Fleet
Developed a real-time tracking API using gRPC and Google Maps API. Handles 10,000 driver locations per second. Improved ETA accuracy by 40%. Tech stack: Go, gRPC, Postgres, Redis.
Why teams hire us.
Senior engineers only
Every API is built by engineers with 8+ years of experience. No juniors. No offshore teams. You work directly with the person coding your API.
Fixed price from the start
After the Roadmap phase (week 2), you get a fixed price quote. No hourly billing. No surprise invoices. The price you see is what you pay.
8-12 week delivery
We ship production-ready APIs in 8-12 weeks. Our process is optimized for speed without cutting corners. 98% of our projects ship on time.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliant APIs by default. Our team has passed 10+ compliance audits. We include encryption, audit logs, and access controls.
Full code ownership
You own the source code, the API spec, and the deployment scripts. No license fees. No vendor lock-in. We hand over everything in your GitHub repo.
3-month warranty
We fix any production bugs within 24 hours for 3 months after launch. No extra cost. This is written into every contract.
