Node.js API Development VendorAPI Development
We build production-grade Node.js APIs in 8-12 weeks. Fixed price, senior engineers, no scope creep.
IRPR is a Node.js API development vendor that builds custom APIs using Express.js, Fastify, or Nest.js. We handle everything from REST endpoints to GraphQL schemas and WebSocket connections.
Our typical Node.js API ships in 8-12 weeks with a fixed price between $80K and $250K. We follow HIPAA, PCI-DSS, and SOC 2 compliance standards for industries that require them.
Founders building a SaaS MVP hire us for a production-ready API backend. CTOs at mid-market companies use us to replace legacy Node.js APIs. Product managers at healthtech firms hire us to build HIPAA-compliant API layers.

Why a Node.js API Development Vendor Matters
A dedicated vendor builds your API right the first time, with production-grade security and performance.
IRPR has shipped 200+ products across 50 countries. Our Node.js APIs handle millions of requests per day for clients in fintech, healthcare, and SaaS. We use Express.js, Fastify, and Nest.js depending on the project needs.
Every API includes automated testing with Jest and Supertest, CI/CD via GitHub Actions, and monitoring with Sentry and Datadog. We deploy to AWS ECS or Lambda for auto-scaling from 0 to 10,000 requests per second.
Generic Dev Shop vs IRPR as Your Node.js API Vendor
Most vendors overpromise and underdeliver. IRPR ships on time, on budget, with senior engineers only.
A generic dev shop often assigns junior developers to your project. They use outdated patterns, skip testing, and deliver APIs that crash under load. You end up paying for rewrites.
IRPR assigns senior Node.js engineers with 8+ years of experience. Every API gets automated tests, CI/CD, and monitoring from day one. We guarantee the timeline and the price.
- Junior developers with 1-2 years experience
- No automated testing or CI/CD
- No monitoring or error tracking
- Hourly billing with no cap
- No compliance knowledge (HIPAA, PCI, SOC 2)
- Scope creep without change orders
- Senior engineers with 8+ years experience
- Jest + Supertest tests, GitHub Actions CI/CD
- Sentry + Datadog monitoring out of the box
- Fixed price from the Roadmap phase (week 2)
- HIPAA, PCI-DSS, SOC 2 compliance built in
- Scope locked after Roadmap, no surprise charges
Our Node.js API Development Process
We follow a 4-phase process to ship your API in 8-12 weeks.
Phase 1 is the Idea phase where we clarify your requirements and define the API endpoints. Phase 2 is the Roadmap phase where we produce a fixed-price quote and a detailed timeline.
Phase 3 is the Product phase where we build, test, and deploy the API. Phase 4 is the Release phase where we hand over the code, set up monitoring, and provide documentation.
What Ships with Every Node.js API
Every project includes these deliverables by default, no extras needed.
We believe in full transparency. You own everything we build, including the source code, tests, and documentation. There are no hidden costs or ongoing license fees.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Automated tests with Jest and Supertest
- OpenAPI / Swagger documentation
- Sentry error tracking configured
- Datadog monitoring and dashboards
- Dockerized development environment
- PostgreSQL or MongoDB schema with migrations
- JWT authentication with refresh tokens
- Rate limiting and input validation

Why teams hire us.
Senior engineers only
Every project gets a lead engineer with 8+ years of Node.js experience. No junior developers, no offshore teams. You talk directly to the person writing your code.
Fixed price, not hourly
We give you a fixed quote during the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. The price you see is the price you pay.
8-12 week timeline
Most Node.js APIs ship in 8-12 weeks. We break the project into weekly sprints with demos every Friday. You see progress and can adjust priorities.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliant APIs. Our team knows the regulatory requirements for healthcare, fintech, and enterprise projects. No after-the-fact fixes.
Full code ownership
You own all source code, tests, and documentation. No proprietary frameworks, no vendor lock-in. You can take the code to any team after launch.
Production-grade monitoring
Every API ships with Sentry error tracking and Datadog monitoring. We set up alerts for p99 latency, error rates, and uptime. You know the health of your API at all times.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
