Expert Node.js API Development VendorNode.js API
We build secure, scalable APIs for your product. Launch in 8-12 weeks with a fixed price.
IRPR builds high-performance Node.js APIs for startups and enterprises. We use Express, Fastify, NestJS, and PostgreSQL to deliver production-ready APIs that handle millions of requests.
Projects ship in 8 to 12 weeks with prices from $80K to $250K. We handle authentication, rate limiting, documentation, and monitoring as standard features.
CTOs who need a reliable API backend, product managers scaling their SaaS, and founders building MVP integrations hire us. We also work with compliance officers who require HIPAA or PCI-ready APIs.
Types of software we ship.
RESTful API
Standard REST APIs with Node.js and Express. Includes JWT auth, pagination, and OpenAPI docs.

The numbers behind our Node.js APIs
Delivered 200+ API projects across 50+ countries.
Every API we build is designed for scale and security. Our clients average 98% on-time delivery with zero unplanned downtime in the first year.
We track metrics like response time (under 200ms p95), error rate (below 0.1%), and uptime (99.9% SLA). These numbers are guaranteed in our contracts.
Why hire a dedicated Node.js API vendor instead of a generalist team?
Most agencies don't specialize in API design, security, or performance.
A generalist team might build your API with inconsistent endpoints, no auth, and zero documentation. That leads to integration headaches and scaling failures.
IRPR focuses exclusively on Node.js APIs. We follow API-first design, use automated testing, and ship complete documentation. This cuts your integration time by 40%.
- No API design standards
- No built-in auth middleware
- No OpenAPI documentation
- Not designed for horizontal scaling
- No monitoring or alerting
- Timeline slips by months
- API-first architecture with standards
- JWT and OAuth2 built in
- Auto-generated OpenAPI docs
- Horizontal scaling ready
- Datadog and Prometheus monitoring
- Fixed 12-week delivery
Our Node.js API development process in 4 phases
From spec to production in 12 weeks.
We start with a 2-week Roadmap where we document your endpoints, data model, and security requirements. You get a fixed price and timeline.
Then we prototype, build, test, and deploy. Each phase has clear milestones and weekly demos. No black boxes.
What ships with every Node.js API project
Everything you need to go live and maintain your API.
We don't just hand you code. We give you a complete production system with documentation, monitoring, and deployment pipelines.
- Source code in your private GitHub repository
- CI/CD pipeline with GitHub Actions
- OpenAPI specification (Swagger UI)
- Postman collection with example requests
- Docker containers for local development
- Sentry error tracking integrated
- Datadog monitoring dashboard
- Rate limiting with Redis
- Unit and integration tests (80%+ coverage)
- 2-week WARP support after launch
What we ship in this practice.
Fintech payment processing API
Built a PCI-compliant payment API using Node.js, Stripe, and PostgreSQL. Reduced transaction processing time by 40% and handled 10,000 requests per minute.
EdTech real-time chat API
Built a WebSocket API with Socket.io and Redis for a live tutoring platform. Supported 10,000 concurrent users with under 50ms latency.
Ecommerce inventory management API
Developed a REST API with Express and MongoDB for a multi-channel retailer. Cut manual stock updates by 15 hours per week and reduced out-of-stock incidents by 30%.
Healthcare telemedicine API
Built a HIPAA-compliant API with Fastify and AWS for a telehealth startup. Processed 1 million patient records with end-to-end encryption.
SaaS integration API for CRM
Created a GraphQL API using Apollo Server and PostgreSQL. Enabled 200+ third-party integrations and reduced deployment time by 50%.
Logistics shipment tracking API
Built an event-driven API with Kafka and Node.js for a supply chain company. Reduced shipment tracking latency by 60% and provided real-time ETAs.
Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote after the 2-week Roadmap phase. No hourly billing, no scope creep charges, no surprise invoices.
Experienced Node.js engineers only
Our team has built over 200 APIs using NestJS, Fastify, and TypeScript. We don't assign junior developers to your project.
In-house QA and security review
Every API passes automated load tests and a manual OWASP Top 10 security audit. We check for SQL injection, XSS, and broken authentication.
2-week WARP support included
After launch you get 2 weeks of WARP support at no extra cost. We monitor your API, fix any issues, and help with minor changes.
Full code ownership
You own 100% of the intellectual property. We deliver all source code, documentation, and deployment configurations to your repository.
Async-first collaboration
We work with teams across all time zones. We maintain a 10-hour overlap with US East Coast hours and use Slack, Notion, and Linear for communication.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
