Expert Node.js API Development CompanyAPI Development
We build production-ready Node.js APIs in 8-12 weeks. Fixed pricing, no scope creep, senior engineers only.
IRPR builds high-performance Node.js APIs for web and mobile applications. We use Express.js, Fastify, or NestJS for REST APIs and Apollo Server for GraphQL, with PostgreSQL or MongoDB for data storage.
Each API project ships with a CI/CD pipeline, automated testing, API documentation (Swagger/OpenAPI), and monitoring (Sentry, Datadog). Typical timeline is 8-12 weeks with fixed pricing from $80K to $250K. We build HIPAA and PCI-DSS compliant APIs when needed.
Startup CTOs needing a scalable backend for their SaaS MVP. Enterprise engineering managers replacing legacy monolithic APIs. Product owners building B2B integrations. Ecommerce directors requiring custom checkout and inventory APIs.
Types of software we ship.
REST API Development
Build stateless RESTful APIs with Express.js and JWT authentication. Supports versioning, rate limiting, and pagination out of the box.

Our Node.js API Development Process
We follow a structured 4-phase process to deliver your API on time and on budget.
Each phase has clear deliverables and milestones. You see progress every week through our project management tools.
The process starts with a Discovery phase where we define architecture, endpoints, and data models.
What Ships with Every Node.js API
Every project includes these deliverables by default.
You get everything needed to run, monitor, and extend your API without relying on us.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Automated unit and integration tests (Jest)
- API documentation (Swagger/OpenAPI)
- Error monitoring with Sentry
- Performance monitoring with Datadog
- Docker containerization
- Deployment scripts for AWS/GCP/Azure
- Postman collection for testing
- 30-day post-launch support
