Expert Node.js Backend Development AgencyNode.js Backend
Build high-performance APIs and microservices with an expert Node.js backend development agency. Ship in 12 weeks with fixed pricing and full ownership.
IRPR builds production-grade Node.js backends using Express, NestJS, TypeScript, PostgreSQL, MongoDB, Redis, and AWS Lambda. Our senior engineers design APIs that handle thousands of requests per second with sub-50ms latency.
We deliver a fully functional backend in 10-14 weeks, with fixed pricing from $80K to $250K. Every project meets compliance requirements including SOC 2, HIPAA, and PCI-DSS, and you own all source code from day one.
Our clients include CTOs scaling SaaS platforms, startup founders launching MVPs, enterprise teams migrating to microservices, and product owners building real-time applications. We work across fintech, healthcare, ecommerce, and more.
Types of software we ship.
REST API Development
Build secure, versioned REST APIs with Express and PostgreSQL. Includes OpenAPI documentation and rate limiting.
GraphQL API Development
Implement flexible GraphQL schemas using Apollo Server and Prisma. Supports subscriptions and real-time updates.
Microservices Architecture
Design and deploy event-driven microservices with Node.js, RabbitMQ, and Docker. Includes service discovery and fault tolerance.
Real-Time Backend
Build WebSocket and Socket.IO backends for live chat, collaboration, and notifications. Uses Redis Pub/Sub for horizontal scaling.
Serverless Backend
Deploy serverless functions on AWS Lambda or Cloud Functions with Node.js. Automatic scaling and pay-per-execution pricing.
API Gateway Design
Configure API gateways with Kong or AWS API Gateway for routing, authentication, and rate limiting. Integrates with existing microservices.
Database Architecture
Design normalized SQL or NoSQL schemas with PostgreSQL, MongoDB, and Redis. Includes indexing strategies and migration scripts.
Backend for Mobile Apps
Develop push notifications, user authentication, and data synchronization backends for iOS and Android using Node.js and Firebase.

Results from expert Node.js backend development
Every backend we ship meets strict uptime, latency, and scalability targets.
Our Node.js backends handle over 10,000 requests per second with 99.9% uptime across AWS and GCP deployments. We use auto-scaling groups and load balancers to ensure consistent performance under traffic spikes.
A typical fintech backend we built processes 500,000 API calls daily with an average response time under 30ms. The system uses PostgreSQL with read replicas and Redis caching.
Why choose an expert Node.js backend agency over a generic dev shop
A generic shop writes code. IRPR engineers architect systems that scale, comply, and ship on time.
Generic dev shops often use junior developers, skip testing, and deliver tangled code with no documentation. They have no compliance expertise and rarely build for production loads.
IRPR assigns only senior Node.js engineers with 8+ years of experience. We write unit and integration tests, generate OpenAPI specs, and deploy with CI/CD pipelines from week 1.
- Junior developers with no Node.js background
- Hourly billing with no fixed scope
- No compliance knowledge (HIPAA, SOC 2, PCI)
- Code delivered without tests or documentation
- Manual deployment, no CI/CD
- No performance or load testing
- Senior Node.js engineers (8+ years)
- Fixed price from the Roadmap phase
- HIPAA, SOC 2, PCI-DSS compliance built in
- Full test suite (unit, integration, e2e) and auto-generated docs
- CI/CD pipeline with GitHub Actions and automated rollbacks
- Load testing with k6 and performance benchmarks
Our Node.js backend development process
We ship in 12 weeks by following a four-phase process that eliminates surprises.
From the first call to deployment, you will know exactly what you get and when. Every phase has a fixed deliverable and a clear sign-off point.
We use Agile sprints with bi-weekly demos so you see progress in real time. Our process is designed for speed without sacrificing quality.
What ships with every Node.js backend project
We deliver more than just a running API. Every project includes these items in your repository.
You get a production-ready codebase with full ownership. No hidden dependencies, no locked-in services.
Our deliverables are designed to let your team continue development immediately after handoff.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- PostgreSQL schema with migrations and indexes
- REST or GraphQL API with OpenAPI documentation
- Unit and integration test suite (Jest or Mocha)
- Docker Compose for local development
- Error tracking with Sentry
- Performance monitoring with Datadog or New Relic
- Load test scripts (k6)
- Deployment runbook and architecture diagram
What we ship in this practice.
Real-time chat backend for a telehealth platform
Built a WebSocket backend with Socket.IO and Redis for 50,000 concurrent users. Reduced message delivery time from 500ms to 50ms. Stack: Node.js, Socket.IO, Redis, AWS ECS.
Payment processing microservice for a fintech startup
Developed a PCI-DSS compliant payment microservice that processes $2 million in transactions monthly. Integrated with Stripe and Plaid. Stack: Node.js, Express, PostgreSQL, Stripe API.
GraphQL API for a SaaS analytics platform
Designed a federated GraphQL schema across 4 microservices. Cut query response time by 60% and enabled real-time dashboards. Stack: Apollo Server, Prisma, PostgreSQL, Redis.
Inventory management backend for an ecommerce brand
Built a RESTful API with automatic stock synchronization across 3 warehouses. Reduced manual data entry by 8 hours per week. Stack: Node.js, Express, MongoDB, AWS Lambda.
Property listing API for a real estate marketplace
Created an MLS-compliant API that ingests 10,000 listings daily from 5 sources. Improved search indexing speed by 4x. Stack: Node.js, NestJS, PostgreSQL, Elasticsearch.
Serverless backend for a mobile fitness app
Deployed a serverless API on AWS Lambda handling 1 million requests per month with zero cold starts. Used CloudFront for global low latency. Stack: Node.js, AWS Lambda, DynamoDB, AppSync.
Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote during the Roadmap phase (week 2). No hourly billing, no surprise invoices. You know the cost before we write a line of code.
Senior engineers only
Our team averages 10 years of Node.js experience. No juniors or outsourced contractors. Every engineer has delivered production backends for SaaS, fintech, and healthcare.
Compliance built in from day one
We embed HIPAA, SOC 2, and PCI-DSS controls into the architecture. Audit logs, encryption at rest and in transit, and role-based access are standard.
Full code ownership
You own all source code, infrastructure scripts, and documentation. No licensing fees, no platform lock-in. The code is yours to deploy anywhere.
Delivered in 12 weeks
Our process is optimized for speed. Most MVPs ship in 12 weeks or less. We have a 98% on-time record across 200+ products.
US timezone overlap
Our engineers work business hours in US timezones (EST, CST, PST). You get daily standups and immediate Slack responses during your working day.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
