Professional Node.js API Development DevelopersAPI Development
Hire senior Node.js engineers who build production-grade APIs in 8-12 weeks. Fixed price, full ownership, and compliance built in from day one.
IRPR builds professional Node.js APIs using Express.js, NestJS, TypeScript, and PostgreSQL or MongoDB. We deliver REST, GraphQL, and WebSocket APIs with Redis caching and Docker containerization.
Every project ships in 8-12 weeks with a fixed price between $50K and $150K. We handle compliance for healthcare (HIPAA), fintech (PCI-DSS), and SaaS (SOC 2) from the start, not as an afterthought.
Startup CTOs hire us to launch their product API. Enterprise engineering managers use us to replace legacy middleware. SaaS founders bring us in to build scalable partner APIs. Fintech companies trust us for compliant transaction APIs.
Types of software we ship.
REST API Development
Design and build RESTful endpoints with OpenAPI 3.0 specs, rate limiting, and pagination. Integrate with Stripe, Auth0, or Salesforce.
GraphQL API Development
Implement a GraphQL gateway with Apollo Server, schema stitching, and resolver optimization. Ideal for aggregating data from multiple sources.
Microservices API Architecture
Decompose monolithic APIs into independent microservices with message queues (RabbitMQ, Kafka) and service discovery via Consul.
Real-Time API (WebSocket)
Build WebSocket-based APIs for chat, live notifications, and collaborative editing using Socket.io or native WebSockets with Redis pub/sub.
Third-Party API Integration
Connect your system to 50+ external APIs including Shopify, HubSpot, Slack, and QuickBooks with retry logic and webhook handling.
API Gateway Development
Create an API gateway with Kong or AWS API Gateway for routing, authentication, rate limiting, and logging across all internal services.
Event-Driven API (Kafka)
Implement event-driven architectures with Apache Kafka or AWS Kinesis. Handles millions of events per minute with exactly-once semantics.
API Security & Authentication
Set up OAuth 2.0, JWT, or OpenID Connect with Auth0 or Okta. Includes API key management, IP whitelisting, and penetration testing.
We build for every business type.
E-commerce
SaaS

Professional Node.js API development with proven results
IRPR has delivered over 200 Node.js APIs across 50 countries, averaging 12 weeks from start to production.
Every API we build starts with a 2-week Roadmap phase where we define endpoints, data models, security requirements, and a fixed price. You know exactly what you get and what it costs before any code is written.
Our senior engineers use TypeScript, automated testing, and CI/CD pipelines to ensure your API is reliable, scalable, and maintainable. We ship with OpenAPI documentation, deployment scripts, and monitoring dashboards.
How IRPR compares to generic development shops
Most agencies bill hourly and deliver late. IRPR uses fixed pricing and a proven delivery system.
Generic dev shops often assign junior developers and change scope mid-project. They may not document APIs or handle security reviews. You end up with unclear costs and buggy endpoints.
IRPR assigns senior Node.js engineers, creates a detailed Roadmap, and delivers on time with full documentation. Every project includes security audits, performance benchmarks, and deployment tooling.
- Hourly billing with no cap
- No fixed deadline or milestones
- Sparse or missing API docs
- No security penetration testing
- No automated CI/CD pipeline
- Code license or escrow issues
- Fixed price after 2-week Roadmap
- 8-12 week delivery guarantee (98% on-time)
- OpenAPI 3.0 spec with Postman collections
- Penetration testing and OWASP compliance
- CI/CD with GitHub Actions and Docker
- Full source code ownership, no licenses
Our 4-phase process for Node.js API development
From discovery to deployment, every phase is designed to reduce risk and accelerate delivery.
We break your API project into four clear phases. Each phase ends with a sign-off, so you stay in control of scope and budget.
Phase 1 focuses on architecture and data modeling. Phase 2 produces a fixed-price roadmap. Phase 3 is iterative development with automated testing. Phase 4 deploys to production with monitoring and alerting.
What ships with every Node.js API project
Every API delivery includes all the tooling you need to run and maintain it in production.
We don't just hand over code. You get a complete operational package: documentation, pipelines, monitoring, and security reports.
Your team can take over immediately because everything is automated and documented. No reverse engineering or guesswork.
- TypeScript codebase with strict mode and linting
- RESTful endpoints with OpenAPI 3.0 specification
- Automated test suite with Jest and Supertest (90%+ coverage)
- CI/CD pipeline via GitHub Actions and Docker Compose
- Docker images and deployment scripts for AWS ECS or Kubernetes
- Security audit report with OWASP Top 10 checks
- API performance benchmark results (latency, throughput)
- Database migration scripts for PostgreSQL or MongoDB
- Sentry error tracking and Datadog monitoring dashboards
- Postman collection and developer onboarding guide
