Professional Node.js API Development ServicesAPI Development
Build fast, secure APIs with senior Node.js engineers. Ship in 8-12 weeks with fixed pricing.
IRPR builds professional Node.js API development services using Node.js, TypeScript, Express, and NestJS. We design RESTful and GraphQL APIs that scale to millions of requests.
Every project ships with a fixed price of $80K-$250K and a timeline of 8-12 weeks. Our APIs meet HIPAA, PCI-DSS, and SOC 2 compliance standards out of the box.
We work with CTOs launching SaaS platforms, founders building MVPs, enterprise teams migrating to microservices, and healthcare startups needing HIPAA-compliant APIs.
Types of software we ship.
REST API Development
Build stateless, cacheable REST APIs with Node.js and Express. Supports JSON, XML, and OAuth 2.0.
GraphQL API Development
Create efficient GraphQL APIs using Apollo Server and TypeGraphQL. Reduces over-fetching and under-fetching.
Microservices API Architecture
Design decoupled microservices with Node.js, Docker, and Kubernetes. Enables independent scaling and deployment.
Real-time API (WebSocket) Development
Implement low-latency WebSocket APIs using Socket.io or ws. Handles 10k+ concurrent connections.
Third-party API Integration
Integrate with Stripe, Salesforce, HubSpot, and 50+ other services. Secure webhook handling and rate limiting.
API Gateway and Proxy Development
Deploy API gateways with Kong or AWS API Gateway. Centralize authentication, throttling, and logging.
Internal API Development for Enterprise
Build internal APIs for data exchange between legacy systems. Uses RabbitMQ, Kafka, and REST.
API Security and Authentication Implementation
Implement JWT, OAuth 2.0, and API key authentication. Includes rate limiting and encryption at rest.
We build for every business type.

Why Professional Node.js API Development Matters
A well-built API is the backbone of modern applications. IRPR delivers production-ready APIs that handle high traffic and sensitive data.
Node.js APIs process up to 50,000 requests per second with proper design. Our team uses event-driven architecture and connection pooling to maximize throughput.
With 200+ APIs shipped, we have optimized for latency, security, and maintainability. Every API includes automated tests, monitoring, and documentation.
The IRPR Difference for Node.js API Development
Most agencies deliver unclear scopes and surprise bills. IRPR gives you fixed pricing and senior engineers from day one.
We start every project with a 1-week Roadmap phase. You get a detailed specification with endpoints, data models, and a fixed price before any code is written.
Our engineers average 10+ years of experience. No junior developers. Every API goes through code review, load testing, and security audit before release.
- Hourly billing with no cap
- Junior developers on your project
- No compliance expertise
- Unclear scope changes mid-project
- No automated testing
- You don't own the full code
- Fixed price from Roadmap phase
- Senior engineers only (10+ years avg)
- HIPAA, PCI-DSS, SOC 2 ready
- Scope locked after Roadmap
- Automated tests and CI/CD included
- You own 100% of the code and IP
Our 4-Step Node.js API Development Process
From idea to production in 8-12 weeks. Each phase has clear deliverables and milestones.
The process is designed to eliminate surprises. You see progress every week and can test the API in staging before launch.
We use agile sprints with a dedicated project manager. Communication happens daily via Slack and weekly demos.
What Ships With Every Node.js API
Every project includes everything you need to run, maintain, and scale your API.
We don't just hand over code. You get a fully documented, tested, and deployed API with monitoring and CI/CD pipelines.
All artifacts are delivered in your own Git repository with full access. No hidden dependencies or licensing fees.
- Source code in your private GitHub/GitLab repo
- CI/CD pipeline with GitHub Actions or GitLab CI
- Postman collection with all endpoints and examples
- API documentation generated from OpenAPI/Swagger
- Sentry error tracking and performance monitoring
- Load testing results using k6 or Artillery
- Deployment scripts for AWS, GCP, or your own servers
- Security audit report covering OWASP top 10
- Unit tests with Jest and integration tests with Supertest
- 30-day post-launch support and bug fixes
