Expert API Development DevelopersAPI Development
We build custom APIs that connect your systems in 8-12 weeks. 200+ products shipped, fixed pricing, zero surprises.
IRPR builds custom APIs using Node.js, Python, Go, and TypeScript. We design RESTful endpoints, GraphQL schemas, and event-driven architectures that handle millions of requests per day.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle compliance for healthcare (HIPAA), fintech (PCI-DSS), and SaaS (SOC 2). You get source code, CI/CD pipelines, and API documentation.
CTOs hire us to replace legacy integration stacks. Product owners hire us to launch new API-first features. Engineering managers hire us when their in-house team lacks bandwidth for a critical API project.
Types of software we ship.
REST API development
Stateless endpoints using HTTP methods. We use Express.js or FastAPI with PostgreSQL and Redis for caching.
GraphQL API development
Single endpoint with flexible queries. We use Apollo Server or Hasura with TypeScript and Prisma.
API integration platform
Connect Salesforce, HubSpot, Stripe, and 20+ other tools into one API layer. We build with MuleSoft or custom Node.js.
Webhook system
Real-time event notifications for your app. We use AWS EventBridge, Stripe webhooks, and custom retry logic.
API gateway
Rate limiting, authentication, and routing for microservices. We use Kong or AWS API Gateway with JWT validation.
Real-time API
WebSocket and Server-Sent Events for live data. We use Socket.io, Redis Pub/Sub, and AWS AppSync.
Internal API for microservices
gRPC or message queues for service-to-service communication. We use RabbitMQ, NATS, and Protocol Buffers.
Public API for third-party developers
Documented, versioned APIs with developer portals. We use Swagger/OpenAPI, Postman collections, and API keys.
We build for every business type.
SaaS companies
Ecommerce brands
Healthcare organizations
Fintech companies
Logistics providers
Why expert API development developers matter for your business
A poorly designed API costs you time, money, and customer trust.
A single API outage can cost an enterprise $300K per hour. Our APIs are built with redundancy, monitoring, and auto-scaling from day one. We use AWS CloudWatch, Datadog, and Sentry to track every request.
Every API we build includes rate limiting, input validation, and automated tests. We ship with 90%+ code coverage and a Postman collection so your team can start integrating immediately.
The difference between generic dev shops and expert API developers
Not all API developers deliver production-ready, secure, scalable systems.
Generic shops hand you code that works locally but fails under load. They skip error handling, documentation, and monitoring. You end up with a fragile API that breaks on edge cases.
IRPR treats every API as a production system. We write integration tests, set up CI/CD, and deploy to a staging environment before going live. Your API is ready for millions of requests from day one.
- No automated tests
- No rate limiting or auth
- No monitoring or alerts
- No documentation
- No staging environment
- No post-launch support
- 90%+ code coverage
- JWT, OAuth2, API keys
- Datadog + Sentry monitoring
- Swagger/OpenAPI docs
- Staging + production deploys
- 2 weeks of free support
How we build your API in 8-12 weeks
Our process is designed for speed without cutting corners.
We start with a 2-week Roadmap phase where we define the API contract, data models, and authentication flow. You get a detailed spec before we write a single line of code.
Then we build in 2-week sprints with demos every Friday. You see working endpoints, test them with Postman, and give feedback. No surprises at the end.
What ships with every API project
You own everything. No black boxes, no vendor lock-in.
When IRPR builds your API, you get the complete source code, infrastructure as code, and monitoring dashboards. Nothing is hidden behind a subscription or license.
We also ship a developer portal with Swagger docs, a Postman collection, and a runbook for your ops team. Your engineers can take over immediately.
- Source code in your GitHub repo
- CI/CD pipeline with GitHub Actions
- API documentation with Swagger/OpenAPI
- Postman collection with example requests
- Monitoring dashboards in Datadog
- Error tracking with Sentry
- Rate limiting and authentication (JWT/OAuth2)
- Automated tests with 90%+ coverage
- Staging and production environments on AWS
- Runbook for your ops team
What we ship in this practice.
Payment processing API for a fintech startup
Built a PCI-DSS compliant payment API that processes 50,000 transactions per day. Reduced payment failure rate by 40%. Tech stack: Node.js, Stripe, PostgreSQL, AWS Lambda.
Patient data API for a telehealth platform
Created a FHIR-compliant API that syncs patient records across 3 EHR systems. Cut data entry time by 12 hours per week. Tech stack: Python, FastAPI, Epic FHIR, HIPAA-compliant AWS.
Order management API for an ecommerce brand
Developed a unified API that connects Shopify, warehouse WMS, and 3PL shipping carriers. Reduced order processing time from 4 hours to 15 minutes. Tech stack: Node.js, GraphQL, Redis, Shopify API.
Real-time tracking API for a logistics company
Built a WebSocket-based API that streams GPS data from 1,000+ delivery trucks. Improved ETA accuracy by 25%. Tech stack: Go, Socket.io, Redis, AWS IoT Core.
Multi-tenant API for a SaaS platform
Designed a GraphQL API serving 500+ tenants with isolated data per customer. Scaled to 10 million requests per day with 99.9% uptime. Tech stack: Hasura, TypeScript, PostgreSQL, SOC 2 compliant.
Content API for a media company
Created a REST API that delivers 50,000 articles per minute to a mobile app with 2 million users. Reduced page load time by 60%. Tech stack: Node.js, Elasticsearch, Redis, CloudFront.
Why teams hire us.
Fixed price, not hourly
Every API project gets a fixed quote during the Roadmap phase (week 2). No hourly billing, no surprise invoices. You know the cost before we start building.
Senior engineers only
Every developer on your project has 8+ years of experience. We do not outsource to junior developers or offshore teams. You talk directly to the engineers building your API.
8-12 week delivery
Your API ships in 8-12 weeks, not 6 months. We use tight sprints with demos every 2 weeks so you see progress and can adjust direction.
Full ownership
You own the source code, the infrastructure, and the documentation. No licenses, no lock-in. You can take the API to any in-house team after launch.
Compliance built in
We have built APIs for HIPAA, PCI-DSS, SOC 2, and FERPA. Your API meets regulatory requirements from day one, not as an afterthought.
Production-ready from day one
Your API ships with monitoring, error tracking, rate limiting, and automated tests. It is ready to handle real traffic on day one, not just a prototype.
Idea → Roadmap → Product → Release.
