Best Node.js API Development VendorAPI Development
We ship production-grade Node.js APIs in 8-12 weeks. Fixed pricing, senior engineers, and full code ownership from day one.
IRPR builds production-grade Node.js API backends for SaaS platforms, mobile apps, and enterprise systems. We use Express, Fastify, and NestJS paired with PostgreSQL, Redis, and AWS or GCP infrastructure.
Every project ships with a fully documented API, CI/CD pipeline, monitoring, and test coverage in 8-12 weeks. Prices range from $80,000 to $250,000. We support HIPAA, PCI-DSS, and SOC 2 compliance out of the box.
CTOs at funded startups hire us to replace unstable MVP backends. Product managers trust us to build scalable APIs for growing user bases. Engineering leaders in healthcare and fintech choose us for compliance-grade APIs without the overhead.
Types of software we ship.
REST API Development
Build RESTful APIs with Express or Fastify. Includes Swagger documentation, rate limiting, and JWT auth. Integrated with Stripe or Twilio.
GraphQL API Development
Design a GraphQL schema with Apollo Server or TypeGraphQL. Supports queries, mutations, subscriptions, and real-time data. Connects to PostgreSQL or MongoDB.
Microservices API Architecture
Decompose a monolith into Node.js microservices with message queues (RabbitMQ) and Docker. Each service scales independently.
Real-Time API (WebSockets)
Build real-time features using Socket.IO or WebSocket. Used for live chat, notifications, and streaming data. Handles 10K+ concurrent connections.
Third-Party API Integration
Connect your app to Salesforce, HubSpot, Slack, or Shopify via their Node.js SDKs. Includes retry logic, caching, and error handling.
API Gateway & Rate Limiting
Set up an API gateway with Kong or Express Gateway. Implements JWT validation, usage quotas, and caching to protect your backend.
Serverless API (AWS Lambda)
Deploy Node.js APIs on AWS Lambda with API Gateway or Vercel. Scales to zero when not in use, saves cost on low-traffic endpoints.
Internal API for Enterprise Systems
Build private APIs that connect ERP, CRM, and HR systems. Uses Okta for SSO and GraphQL for flexible data access across departments.
We build for every business type.
SaaS platforms
Fintech companies
Healthcare organizations
Ecommerce brands
Mobile app backends
Why IRPR is the Best Node.js API Development Vendor
We have shipped over 200 Node.js APIs for startups and enterprises across 50 countries.
Every API we build is designed for scale, security, and maintainability. Our senior engineers follow a strict architecture review, code review, and automated testing process. The result is an API that works under load and is easy to extend.
We use a fixed-price model so you know the cost upfront. After a 2-week Roadmap phase, we quote a fixed price for the full build. There are no hourly surprises or scope creep fees.
Generic Dev Shop vs IRPR: The Difference
Most agencies cut corners on Node.js API projects. We don't.
A typical dev shop assigns junior developers and bills by the hour. They reuse boilerplate code, skip tests, and deliver undocumented endpoints. You pay for their learning curve.
IRPR assigns senior engineers with 10+ years of experience. Every API includes full test coverage, CI/CD, monitoring, and Swagger docs. You own the code from commit one.
- Hourly billing, no upfront price
- Junior or mid-level developers
- No architecture review
- Code ownership not guaranteed
- Ships without tests or docs
- No post-launch support
- Fixed price after Roadmap phase
- Senior engineers only (10+ yrs)
- Architecture review before coding
- Full code ownership from day one
- Unit, integration, load tests + Swagger docs
- 3 months of post-launch support included
How We Build Your Node.js API
Our process is designed for speed and quality. No wasted cycles.
We break every API project into four phases. Each phase has a clear deliverable so you always know where we stand.
The entire process takes 8-12 weeks from Roadmap to production. We iterate in 2-week sprints with demos every Friday.
What Ships with Every Node.js API
You get a production-ready API, not just code.
Every project includes the following deliverables by default. There are no optional extras or hidden fees.
All artifacts are yours. We retain nothing.
- Source code in your GitHub repository
- Swagger/OpenAPI documentation
- Postman collection with examples
- CI/CD pipeline using GitHub Actions
- Sentry error tracking configured
- Datadog monitoring dashboard
- Unit and integration tests (90%+ coverage)
- Load testing report (artillery or k6)
- Docker container and docker-compose setup
- SSL/TLS and HTTPS enforced
What we ship in this practice.
Payment Processing API for a Fintech Startup
Built a PCI-DSS compliant payment API using Node.js, Express, and Stripe. Integrated with Plaid for bank verification. Reduced transaction failure rate by 30% and cut integration time for partners by 2 weeks.
Telehealth API for a Healthcare Platform
Created a HIPAA-compliant API with Fastify, PostgreSQL, and Twilio Video. Handled 5000 concurrent video sessions. Eliminated manual appointment scheduling and saved the client 40 hours of admin work per week.
Headless Commerce API for an Ecommerce Brand
Developed a GraphQL API with Apollo Server and MongoDB. Integrated with Shopify and Stripe. The client saw a 25% increase in conversion rates due to faster product load times.
Real-Time Chat API for a Social App
Built a WebSocket API using Socket.IO and Redis. Supported 50,000 concurrent users with sub-100ms latency. Reduced server costs by 40% compared to the previous polling-based approach.
Inventory Management API for a Logistics Company
Created a REST API with Express and PostgreSQL. Integrated with warehouse scanners via MQTT. Reduced inventory discrepancies by 80% and cut order fulfillment time from 4 hours to 45 minutes.
SaaS Subscription API for a B2B Platform
Designed a multi-tenant GraphQL API with NestJS and Stripe Billing. Automating invoicing and seat management saved the client $15,000 per month in manual billing overhead.
Why teams hire us.
Fixed price, not hourly
Every Node.js API project gets a fixed quote after the 2-week Roadmap phase. You know the exact cost before any development starts. No hourly billing, no surprise invoices.
Senior engineers only
Our team averages 12 years of experience in Node.js and backend engineering. We do not use junior developers or outsource to low-cost markets. You work directly with the engineers building your API.
Full code ownership
You own every line of code from day one. We push to your GitHub repository on day one of development. There are no licensing fees, no IP retainers, no locked-in contracts.
8-12 week delivery
We ship a production-ready API in 8 to 12 weeks. That includes architecture, build, testing, documentation, and deployment. Our 98% on-time rate means you can plan your launch with confidence.
Compliance built in
We have built Node.js APIs for HIPAA, PCI-DSS, and SOC 2 environments. Our infrastructure templates include encryption at rest, audit logging, and access controls by default. No retrofitting needed.
Post-launch support included
Every project comes with 3 months of post-launch support. We monitor uptime, fix bugs, and help with any integration questions. After that, we offer ongoing retainer options or you take over.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
