Experienced Node.js Backend Development ServicesBackend Development
We build production-grade Node.js backends that scale. Fixed price, 8-12 week delivery, full code ownership.
IRPR builds experienced Node.js backend development services for companies that need reliable, scalable server-side systems. We use Node.js with Express, NestJS, TypeScript, PostgreSQL, Redis, and AWS Lambda to deliver production-ready APIs and microservices.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. Our backends meet compliance standards including HIPAA, PCI-DSS, and SOC 2, passing rigorous third-party audits before launch.
CTOs at SaaS startups hire us to build their core API layer. Heads of Engineering at fintech companies trust us for payment processing and data pipelines. Product Managers at healthcare platforms need our HIPAA-compliant backends. Tech leads at ecommerce brands bring us in for real-time inventory and checkout systems.
Types of software we ship.
REST API development
Build CRUD endpoints with Express or NestJS, including authentication, rate limiting, and Swagger documentation.
GraphQL API development
Implement GraphQL schemas using Apollo Server or Yoga, with resolver optimization and subscription support.
Real-time chat backend
WebSocket and Socket.IO servers for live messaging, with message queues (Redis Pub/Sub) and presence detection.
Payment processing backend
Integrate Stripe, Braintree, or Adyen with idempotency keys, webhook handling, and PCI-DSS compliant tokenization.
Microservices architecture
Design and deploy independent Node.js services with RabbitMQ or Kafka, each with its own database and CI/CD pipeline.
Backend as a Service (BaaS)
Pre-built auth, file storage, email, and push notifications exposed via SDKs — think Firebase but self-hosted on AWS.
Serverless functions
AWS Lambda, Cloud Functions, or Vercel Edge Functions triggered by HTTP events, scheduled tasks, or S3 events.
Authentication system
OAuth2, JWT, and SSO implementations with Passport.js, Auth0 integration, and multi-tenancy support.
We build for every business type.
SaaS startups
Fintech companies
Ecommerce brands

What Our Experienced Node.js Backend Development Services Deliver
Every backend ships with measurable results from 200+ projects across 50 countries.
IRPR has delivered 200+ production Node.js backends. 98% of projects launch on time. Average timeline for an MVP backend is 12 weeks. Our hosted services maintain 99.9% uptime across AWS, GCP, and Azure.
We use Node.js v20 with Express 4.x or NestJS 10.x. Databases: PostgreSQL 16 for relational data, Redis 7 for caching, MongoDB 7 for document storage. Every backend includes automated CI/CD, Sentry error tracking, and Datadog monitoring.
Why Generic Dev Shops Fail at Node.js Backend Development
Most agencies lack deep Node.js expertise. They deliver brittle code, miss security baselines, and blow budgets.
Generic shops often assign junior Node.js developers with no experience in production backends. They skip load testing, leave endpoints unauthenticated, and write monolithic code that cannot scale. We have seen projects where the first deploy took 12 months and still had 40 critical bugs.
IRPR assigns senior Node.js engineers who have built backends for compliance-heavy industries. We write tests for every endpoint, enforce TypeScript strict mode, and audit dependencies for vulnerabilities before the first commit.
- Junior developers with minimal Node.js experience
- No TypeScript — plain JavaScript with runtime errors
- No automated load testing
- Inconsistent error handling across endpoints
- No CI/CD — manual deploys to staging only
- Hourly billing with scope creep
- Senior Node.js engineers with 8+ years experience
- TypeScript with strict mode and full test coverage
- k6 and Artillery load testing before every release
- Standardized error objects with Sentry integration
- CI/CD pipeline with GitHub Actions and automated rollbacks
- Fixed price from Roadmap phase — no surprises
Our 4-Phase Process for Experienced Node.js Backend Development
From concept to production in 8-12 weeks. Each phase includes specific deliverables and a fixed price.
Every engagement follows our Idea - Roadmap - Product - Release framework. Phase 1 (Idea) takes 3-5 days — we map your use case, data model, and third-party integrations. Phase 2 (Roadmap) takes 7 days — you get a fixed quote, Gantt chart, and architectural decision record.
Phase 3 (Product) is the main build — 6-8 weeks for a full backend. Phase 4 (Release) includes deployment, monitoring setup, and a 30-day warranty. We require your code in your repo from day one.
What Ships with Every Node.js Backend Project
All deliverables are listed in the Roadmap. No hidden items.
Every project includes source code, infrastructure code, and documentation. We ship a complete package that your team can extend immediately. No dependencies on IRPR after the warranty period.
Our checklist covers production readiness. We ensure the backend passes OWASP Top 10 security checks, handles 1000 requests per second under load, and integrates with your chosen services.
- Source code in your GitHub/GitLab/Bitbucket repo
- CI/CD pipeline using GitHub Actions or GitLab CI
- Docker Compose and Dockerfiles for local development
- PostgreSQL migrations with Flyway or Prisma
- Swagger/OpenAPI 3.0 endpoint documentation
- Sentry error tracking with alerting
- Datadog or Grafana dashboards for metrics
- Load test scripts (k6 or Artillery) in the repo
- Vulnerability scan report from Snyk or Dependabot
- README with architecture diagram and runbook
What we ship in this practice.
Payment processing backend for a fintech startup
Built a PCI-DSS compliant payment gateway using Node.js, Stripe Connect, and PostgreSQL. Reduced transaction failure rates from 3.2% to 0.4%. Handles 5000 requests/second during peak hours.
Multi-tenant API for a SaaS HR platform
Designed a microservices backend with NestJS, PostgreSQL, and Redis pub/sub. Supports 200 tenants with isolated data. Reduced onboarding time from 4 weeks to 2 days per tenant.
Real-time inventory backend for an ecommerce brand
Deployed a WebSocket server with Socket.IO and Redis to sync inventory across 15 warehouses. Cut inventory discrepancies by 92% and enabled real-time stock visibility on product pages.
HIPAA-compliant patient portal backend for a telemedicine company
Developed a backend with Node.js, Express, and MongoDB with full audit logging. Passed HIPAA security risk assessment in week 10. Supports 10,000 concurrent video sessions.
MLS data ingestion pipeline for a real estate platform
Built an ETL pipeline using Node.js, AWS Lambda, and PostgreSQL to sync listings from 50 MLS providers. Indexes 2 million properties with updates every 15 minutes.
Subscription billing backend for a media streaming service
Created a usage-based billing backend with Node.js, Recurly, and Redis. Supports tiered pricing, free trials, and invoicing. Reduced billing errors by 78% after launch.
Why teams hire us.
Fixed price from week 2
Every project gets a fixed quote during the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. The price covers everything in the Roadmap.
Senior Node.js engineers only
Every engineer on your project has 8+ years of Node.js experience. We do not use junior or offshore developers. Our team averages 3 years working together at IRPR.
Compliance ready by default
Our backends are built to pass HIPAA, PCI-DSS, and SOC 2 audits from day one. We include audit logging, encryption at rest and in transit, and access controls without extra cost.
Full code ownership
You own every line of code written for your project. We put it in your repository from the first commit. No licensing fees, no platform lock-in, no hidden IP.
2-hour response SLAs in production
After launch, we offer a 30-day warranty with 2-hour critical bug response. For ongoing support, we have retainer plans starting at 10 hours per month.
Load tested to your scale target
Before release, we run load tests with k6 or Artillery matching your projected traffic. We optimize until your backend handles at least 3x your target requests per second.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
