Top Node.js Backend Development ServicesBackend Development
Senior Node.js developers build your backend from scratch. 8-12 week MVP delivery with fixed pricing.
IRPR builds backend systems with Node.js, Express.js, and NestJS. We handle everything from REST APIs and GraphQL endpoints to microservices and event-driven architectures.
Every backend ships in 8 to 12 weeks with a fixed price between $80,000 and $250,000. We support PCI-DSS for fintech, HIPAA for healthcare, and SOC 2 for SaaS environments.
CTOs hire us to replace slow in-house teams. Startup founders hire us to get their first product to market. SaaS companies hire us to rebuild monolithic backends into decoupled microservices.
Types of software we ship.
REST API development
Build stateless RESTful APIs with Express.js or Fastify. Supports JWT auth, rate limiting, and OpenAPI docs.
GraphQL API development
GraphQL backends using Apollo Server or Yoga. Single endpoint, type-safe, and perfect for complex data fetching.
Microservices architecture
Decompose monoliths into small Node.js services with message queues like RabbitMQ or NATS.
Real-time backend services
Build WebSocket servers with Socket.io or uWebSockets.js for live chat, notifications, and collaborative editing.
Serverless backend
AWS Lambda functions with Node.js runtime. Event-driven, auto-scaling, and zero server management.
SaaS backend development
Multi-tenant Node.js backends with Stripe billing, user roles, and tenant isolation.
Ecommerce backend
Node.js checkout pipelines, inventory sync with Shopify API, and payment gateway integration (Stripe, PayPal).
Data processing backend
Node.js ETL pipelines with Bull queues and Redis. Process CSV imports, PDF generation, and image resizing at scale.
We build for every business type.
Technology startups
Ecommerce brands

Node.js backend development metrics that matter
Numbers from 200+ Node.js projects IRPR has shipped since 2016.
Our Node.js backends process over 1 million API requests per day on average. Each API response stays under 200ms p95. We build with Express.js, NestJS, or Fastify depending on your traffic patterns.
Every backend includes automated CI/CD pipelines using GitHub Actions or GitLab CI. We deploy to AWS ECS, DigitalOcean App Platform, or your own servers. Uptime is 99.9% backed by SLA.
IRPR vs other Node.js development shops
Most backend agencies overpromise and underdeliver. IRPR ships on time and on budget.
We assign senior Node.js engineers only. No juniors, no interns. You get a single point of contact and a dedicated team of 2-4 engineers.
Every project starts with a 2-week Roadmap phase. You get a fixed price, a detailed specification, and a delivery timeline before a single line of code is written.
- Junior developers on your account
- Hourly billing with no cap
- No clear specification before starting
- Lack of compliance experience (HIPAA, PCI)
- Delayed timelines and scope creep
- Generic boilerplate code
- Senior Node.js engineers only
- Fixed price for entire project
- 2-week Roadmap phase with full spec
- HIPAA, PCI-DSS, SOC 2 compliance built-in
- 8-12 week delivery, 98% on-time rate
- Custom architecture and test coverage
How we build your Node.js backend in 8 weeks
Our process from idea to production backend.
We follow a four-phase approach: Idea, Roadmap, Product, Release. The Roadmap phase takes 2 weeks and produces a functional specification with user stories, data models, and API contracts.
The Product phase takes 6-10 weeks depending on complexity. We build in 2-week sprints with daily standups and a continuous deployment pipeline. You see working software every sprint.
What ships with every Node.js backend
Your backend comes with production-ready infrastructure, not just code.
We ship a fully tested Node.js backend with CI/CD pipelines, logging, monitoring, and security scanning. You get a complete deployment playbook and access to your own GitHub repository from day one.
No black box. No code hostages. You own every line of code, every Dockerfile, and every CI configuration file.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions (tests, lint, deploy)
- REST or GraphQL API documentation (OpenAPI or GraphQL schema)
- Sentry error tracking integrated
- Datadog or Prometheus monitoring dashboards
- Docker Compose setup for local development
- PostgreSQL or MongoDB database schema migrations
- Stripe or Plaid test mode integration
- Authentication system (JWT or OAuth2 with Auth0)
- Deployment runbook and architecture diagram
What we ship in this practice.
SaaS subscription backend
Built a Node.js backend with Stripe billing, user tiers, and webhook handling. Reduced failed payment retries by 80%. Tech stack: NestJS, PostgreSQL, Redis, Stripe API.
Real-time collaboration backend
Developed a WebSocket server for live document editing. Handles 10,000 concurrent connections with less than 50ms latency. Tech stack: Socket.io, Redis, MongoDB, AWS ECS.
Ecommerce order processing API
Replaced a PHP backend with a Node.js microservices architecture. Order processing time dropped from 12 seconds to under 1 second. Tech stack: Fastify, RabbitMQ, PostgreSQL, Shopify API.
Healthcare appointment scheduling backend
Built a HIPAA-compliant backend for a telehealth startup. Handles SOAP messages and FHIR resources. Reduced scheduling errors by 95%. Tech stack: Express.js, MongoDB, Twilio, HIPAA logs.
Fintech payment gateway backend
Designed a PCI-DSS Level 1 compliant payment gateway with tokenization and fraud detection. Processes 5,000 transactions per minute. Tech stack: Node.js, PostgreSQL, Redis, Plaid API.
Real estate MLS sync service
Created a background job that syncs MLS listings every 15 minutes. Handles 500,000+ property records with differential updates. Tech stack: Bull queues, Node.js, PostgreSQL, AWS Lambda.
Why teams hire us.
Senior Node.js engineers only
Every engineer on your project has 5+ years of Node.js experience. No juniors. No interns. You talk directly to the developers building your backend.
Fixed price, no hourly billing
After the 2-week Roadmap phase, you get a fixed price. No hourly rates. No surprise invoices. You know the total cost before a line of code is written.
8-12 week MVP delivery
From kickoff to production, your backend ships in 8-12 weeks. We have a 98% on-time delivery rate across 200+ products shipped.
Compliance built in, not bolted on
We build HIPAA, PCI-DSS, SOC 2, and FERPA compliance into your backend from day one. No audits, no rework, no surprises.
You own everything
Source code, Docker images, CI/CD scripts, and documentation are all yours. No proprietary frameworks. No code escrow. You can move your backend anywhere.
30-day post-launch warranty
After deployment, we fix any bugs or performance issues for 30 days at no extra cost. Your backend is production-ready and monitored.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
