Best API Development DevelopersAPI Development
We build REST, GraphQL, and microservice APIs. Get a fixed-price, 12-week timeline with full ownership.
IRPR builds best-in-class APIs for web and mobile applications. We use Node.js, Python, Go, and Postgres with automated testing and CI/CD.
Every API project ships in 12-14 weeks with fixed pricing from $80K to $250K. We handle security compliance (HIPAA, PCI-DSS, SOC 2) and deploy with Kubernetes and AWS.
We work with CTOs scaling a SaaS platform, product managers launching a mobile app, healthcare startups needing HIPAA-compliant backends, and enterprises migrating to microservices.
Types of software we ship.
RESTful API Development
Build stateless, resource-oriented APIs using Express.js or FastAPI. Includes pagination, filtering, and versioning.
GraphQL API Development
Flexible query APIs with Apollo Server and Prisma. Clients fetch exactly what they need, reducing overfetching.
Microservices Architecture
Decompose monoliths into independent services with message brokers like RabbitMQ or Kafka.
Third-Party API Integration
Connect your app to Stripe, Twilio, Salesforce, Slack, or any external service. Retry logic and webhook handling included.
API Gateway Development
Centralized routing, authentication, and rate limiting using Kong or AWS API Gateway for multi-service backends.
Webhook Systems
Event-driven notifications sent to user endpoints. Built with Redis queues and signed payloads for security.
Real-Time API (WebSocket)
Sub-second push updates for chat, live dashboards, or gaming using Socket.IO or WebSocket with AWS AppSync.
API Security Audit and Hardening
OWASP Top 10 checks, OAuth2/OpenID Connect implementation, and automated vulnerability scanning with Snyk.
We build for every business type.
SaaS platforms
Mobile apps
Ecommerce platforms
Healthcare applications
Fintech products
Why Choose the Best API Development Developers
IRPR delivers production-ready APIs that scale, secure, and ship on time.
Every API we build starts with a detailed OpenAPI specification so you know exactly what you get before we write code. We include unit tests, integration tests, and load testing that validate 90%+ code coverage.
Our team has shipped 200+ APIs across 50 countries with 98% on-time delivery. We deploy to AWS or GCP using Kubernetes and infrastructure as code, ensuring 99.9% uptime from launch.
Generic Dev Shop vs IRPR
The difference between a generic dev shop and IRPR is night and day. Here is what we do differently.
Many agencies start coding without a solid API contract. They skip documentation and testing to rush a demo, then bill you for every change. You end up with a fragile API that breaks in production.
IRPR works the opposite way. We define the API contract first as an OpenAPI spec. We build automated tests, auto-generate docs, and run security scans before deployment. You get a fixed price and full ownership.
- No clear API design before coding
- No automated testing
- No documentation beyond basic endpoints
- Hourly billing with scope creep
- No security audit or OWASP checks
- Manual deploy with no CI/CD
- OpenAPI specification approved before development
- Unit + integration tests with 90%+ coverage
- Auto-generated documentation via Swagger/Postman
- Fixed price after Roadmap phase
- Security scan in Roadmap (Snyk, OWASP)
- GitHub Actions CI/CD pipeline with Docker and Kubernetes
Our API Development Process
We follow a structured 4-phase process that eliminates surprises and delivers a production-ready API on schedule.
Phase 1 and 2 focus on specification and architecture. You approve the API contract and tech stack before any code is written. Phase 3 and 4 deliver the product with full testing and deployment scripts.
Every phase ends with a review and milestone. You see progress every week in our shared project board.
What Ships with Your API
Every API project from IRPR comes with a complete set of deliverables so your team can maintain and extend the system immediately.
We treat the API as a product, not a prototype. That means production-grade infrastructure, monitoring, and documentation from day one.
- Source code in your GitHub repository
- OpenAPI/Swagger documentation
- CI/CD pipeline on GitHub Actions
- Postman collection for manual testing
- Deployment guide with Kubernetes manifests
- Sentry error tracking configured
- Datadog monitoring dashboard
- Docker containers for local development
- Load testing results (k6 or Artillery)
- Security scan report (Snyk)
What we ship in this practice.
Real-time data sync API for logistics
Built a WebSocket API that syncs shipment tracking data across 3 warehouses. Reduced manual data entry by 10 hours per week. Tech stack: Node.js, Socket.IO, Redis, AWS DynamoDB.
HIPAA-compliant patient data API
Developed a FHIR-based REST API for a telemedicine platform enabling secure sharing of patient records with 15 hospital systems. Tech stack: Python, FastAPI, PostgreSQL, AWS Lambda.
Payment gateway aggregation API
Created a unified payment API that processes transactions through Stripe, Square, and PayPal with a single endpoint. Handles $5M in monthly volume. Tech stack: Go, PostgreSQL, RabbitMQ.
Inventory management API for ecommerce
Built a REST API that syncs inventory across 50 product catalogs in real time. Reduced overselling by 95%. Tech stack: Node.js, MySQL, Redis, AWS SQS.
Content delivery API for media platform
Designed a GraphQL API serving 2M requests per day to a video streaming app. Cut response times by 60% with caching. Tech stack: GraphQL, Apollo Server, MongoDB, CloudFront.
Property listing API for real estate
Developed a REST API that aggregates MLS data from 3 sources into a single searchable index. Connected 10,000+ listings. Tech stack: Python, Elasticsearch, Redis, AWS Fargate.
