Leading Node.js API Development PartnerDevelopment Partner
We build production-ready Node.js APIs for SaaS platforms, fintech apps, and ecommerce marketplaces. Get a fixed price in 2 weeks and ship in 8-12 weeks.
IRPR builds high-performance Node.js APIs using Express, Fastify, and NestJS. We integrate with PostgreSQL, Redis, Kafka, and AWS Lambda for scalable backend systems.
We ship a complete, documented API in 8-12 weeks with fixed pricing from $80K-$250K. Our APIs pass security audits for HIPAA, PCI-DSS, and SOC 2.
CTOs at funded startups hire us to build their core backend. Product managers at mid-market companies need custom API integrations. Enterprise IT directors use us to modernize legacy systems with microservices.
Types of software we ship.
REST API Development
Build RESTful APIs with Express or Fastify, connected to PostgreSQL or MongoDB. Includes OpenAPI spec and Swagger docs.
GraphQL API Development
Design GraphQL APIs using Apollo Server or Yoga. Resolvers connect to any data source with batching and caching.
Microservices API Development
Break monolithic backends into Node.js microservices. Use NATS, RabbitMQ, or Kafka for event-driven communication.
WebSocket API Development
Real-time APIs with Socket.io or native WebSockets. Support chat, live updates, and collaborative features at scale.
Payment API Integration
Integrate Stripe, Braintree, or Square APIs for payment processing. Handles subscriptions, refunds, and webhooks.
CRM API Integration
Connect Node.js APIs to Salesforce, HubSpot, or Zoho CRM. Sync contacts, deals, and activities bi-directionally.
Data ETL API Development
Build data pipelines with Node.js using Airbyte or custom ETL scripts. Ingest, transform, and load data into BigQuery or Snowflake.
Real-time Data API Development
Create APIs for live dashboards using Redis pub/sub and Socket.io. Stream analytics, IoT data, or market prices under 100ms latency.
We build for every business type.

Why IRPR is a leading Node.js API development partner
We deliver Node.js APIs that handle millions of requests per day, with documentation and monitoring included.
Our team has shipped over 200 products across 50 countries. Each API project follows a structured 4-phase process: Idea, Roadmap, Product, Release. In the Roadmap phase (week 2), you get a fixed quote and a detailed technical plan.
We use Node.js with TypeScript, Express, and Fastify for REST APIs, and Apollo Server for GraphQL. Every API includes automated tests, CI/CD pipelines, and error tracking with Sentry. Post-launch, we provide 60 days of production support.
What sets IRPR apart from other Node.js API development partners
Most dev shops bill hourly and hand over incomplete code. IRPR gives you a fixed price, full ownership, and a production-ready API.
Many agencies promise custom APIs but deliver poorly documented endpoints that break after scaling. They use junior developers and bill for every change request.
IRPR assigns senior engineers only — each with over 7 years of Node.js experience. We write integration tests, performance benchmarks, and API documentation as part of the fixed price. No scope creep, no surprise invoices.
- Hourly billing with no budget cap
- Junior or outsourced developers
- No API documentation or versioning
- No tests or CI/CD pipelines
- Code ownership is unclear
- Post-launch support is extra
- Fixed price from the Roadmap phase
- Senior engineers only (7+ years experience)
- OpenAPI/Swagger docs shipped with every API
- Automated testing and CI/CD on GitHub Actions
- Full code ownership from day one
- 60-day production support included
Our 4-phase process for building your Node.js API
From idea to production in 8–12 weeks. Each phase has clear deliverables and a fixed price.
We start with a 1-2 week kickoff where we map your requirements and define the API contract. Then we move into Roadmap, where you get a detailed technical plan and a fixed quote.
During Product (weeks 3-10) we build, test, and deploy your API. In Release, we launch with documentation, monitoring, and a handover call.
What you get when you ship an API with IRPR
Every Node.js API project includes these deliverables by default — no extra charges.
Other agencies treat documentation, testing, and deployment as separate line items. At IRPR, they are part of the fixed price. You get everything you need to maintain and scale your API in-house.
We also provide a handover session where we walk your team through the codebase, API endpoints, and deployment scripts. Recordings are shared for future reference.
- Source code in your own GitHub/GitLab repository
- OpenAPI 3.0 specification (JSON and YAML)
- CI/CD pipeline with GitHub Actions (build, test, deploy)
- Automated unit and integration tests (Jest, Supertest)
- Sentry error tracking pre-configured
- Deployment to AWS (ECS, Lambda) or your own cloud
- PostgreSQL schema migrations with knex or Prisma
- API authentication guide (OAuth, JWT, API keys)
- 60-day production support via Slack and video calls
- One-hour handover session with screen recording
What we ship in this practice.
Customer-facing API for a SaaS analytics platform
Built a public REST API using Express and PostgreSQL that let customers pull their data programmatically. The API handled 50,000 requests/day in the first month and reduced support tickets by 40%.
Payment processing API for a fintech startup
Integrated Stripe Connect with a custom Node.js API using Fastify. The API managed payouts, refunds, and subscription billing across 12 currencies. Transaction volume reached $2M/month.
Healthcare data exchange API for a telemedicine platform
Developed a HIPAA-compliant API with NestJS and Firebase that synchronizes patient records between clinics and mobile apps. Reduced data entry errors by 60% and met audit requirements.
Inventory sync API for an ecommerce marketplace
Created a GraphQL API using Apollo Server that connected Shopify, WooCommerce, and custom warehouse systems. Real-time inventory updates cut overselling incidents by 90%.
Real-time tracking API for a logistics company
Built a WebSocket API with Socket.io and Redis that streams GPS positions from 500 delivery vehicles. Latency stayed under 200ms, and client dashboards updated every second.
Event-driven microservices API for a media platform
Designed a suite of microservices with Kafka and Fastify for video processing, user subscriptions, and content recommendations. The system scaled to handle 1 million concurrent users during campaign launches.
Why teams hire us.
Fixed price, not hourly
Every API project gets a fixed quote during the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write a line of code.
Senior engineers only
All IRPR engineers have 7+ years of Node.js experience. We assign a dedicated lead developer who stays on your project from kickoff to release. No junior or offshore switcheroos.
Full code ownership
You own 100% of the source code, documentation, and deployment scripts from day one. No licenses, no proprietary frameworks. You can take the code to any team after the project ends.
Security-first development
We follow OWASP guidelines and use Helmet, rate limiting, input validation, and encrypted secrets. Our APIs pass third-party security audits for HIPAA, PCI-DSS, and SOC 2.
CI/CD by default
Every API ships with a GitHub Actions pipeline that runs tests, lints code, and deploys to staging or production automatically. You get Sentry error tracking and Datadog monitoring out of the box.
Dedicated project manager
You get a single point of contact who schedules demos, manages milestones, and communicates via Slack or email. No ghosting, no waiting for responses. Average response time is under 2 hours during business days.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
