Experienced Node.js Backend Development VendorNode.js Backend
We build production-ready Node.js backends with senior engineers. Fixed price, 8-12 week MVPs, and full ownership.
IRPR is an experienced Node.js backend development vendor. We build backends using Express, NestJS, PostgreSQL, Redis, and AWS Lambda. Every line of code is clean, tested, and ready for production.
We ship working software in 8-12 weeks for $80K-$250K. Our backends are PCI-DSS, HIPAA, and SOC 2 compliant. You get a fixed price and full code ownership from day one.
Our clients include CTOs of scaling SaaS companies, startup founders validating MVPs, and enterprise teams needing security-compliant backend infrastructure. They hire us because we deliver on time and write code that lasts.
Types of software we ship.
REST API
Stateless JSON endpoints built with Express or Fastify. Includes rate limiting, caching with Redis, and JWT auth.
GraphQL API
Single endpoint with Apollo Server, type-safe schemas, and resolver batching. Integrates with PostgreSQL via Prisma.

Why hire an experienced Node.js backend development vendor
A generic Node.js developer can write code. An experienced vendor delivers a production-ready system with security, monitoring, and scaling built in.
When you hire a single developer, you get one person's knowledge. When you hire IRPR, you get a team that has shipped 200+ backends across 50+ countries. We know the edge cases: database migrations without downtime, API rate limiting that works under 10K requests per second, and idempotency for payment webhooks.
Our Node.js backends average 99.9% uptime. We use Sentry for error tracking, Datadog for performance monitoring, and write automated tests in Jest that run in CI. Every client receives a deployment runbook and a support SLA.
Generic dev shop vs IRPR: the Node.js backend vendor difference
Not all Node.js development vendors are the same. Here is what you get with IRPR versus a typical agency.
Many shops assign junior developers to keep costs low. They use hourly billing, write untested code, and disappear after launch. You are left with technical debt and a fragile backend.
IRPR is different. We assign senior Node.js engineers only, bill fixed price, and deliver a fully tested, documented backend with CI/CD. You own everything from day one.
- Junior developers with 1-2 years of Node.js experience
- Hourly billing with no cap
- No automated tests
- No CI/CD pipeline
- No code review process
- No documentation of APIs
- Senior Node.js engineers with 8+ years each
- Fixed price quoted in Roadmap phase, no surprises
- Unit and integration tests in Jest, run in CI
- CI/CD via GitHub Actions with auto-deploy
- Code review every sprint by a second engineer
- API documentation generated from code (Swagger)
Our process for building your Node.js backend
Every project follows a four-phase process that removes guesswork. You know the timeline and price before any code is written.
Phase 1 (Idea) is a two-day discovery session where we define the API contract, data model, and deployment architecture. You get a technical specification document.
Phase 2 (Roadmap) produces a fixed-price quote and a 2-week sprint plan. We break the backend into smaller milestones so you see progress every two weeks.
What ships with every Node.js backend from IRPR
You are not just getting code. You get a complete production-ready system with all the tools needed to run it.
Every backend includes automated deployment scripts, database migrations, and a monitoring dashboard. We do not cut corners on infrastructure.
- Source code in your GitHub repository
- CI/CD pipeline on GitHub Actions with automatic deploy to staging
- PostgreSQL database schema with migration scripts
- REST or GraphQL API with Swagger/OpenAPI documentation
- Unit and integration tests (Jest, 80%+ coverage)
- Docker containers for local development and production
- Deployment scripts for AWS ECS or Lambda
- Sentry error tracking and Datadog performance monitoring
- Rate limiting and input validation middleware
- Post-launch support SLA with 4-hour response time
What we ship in this practice.
SaaS subscription API
Built a multi-tenant Node.js backend with Stripe Billing, PostgreSQL, and Redis caching. Reduced billing reconciliation time by 12 hours per week. Stack: Express, Prisma, Stripe, AWS RDS.
Real-time chat backend
Developed a WebSocket server using Socket.io and Redis Pub/Sub for a social platform. Handles 50K concurrent connections with 99.9% uptime. Stack: Node.js, Socket.io, Redis, Docker.
Ecommerce order management
Created a Node.js backend with Express, MongoDB, and Bull queue for order processing. Cut order processing latency from 2 seconds to 200ms. Stack: Express, MongoDB, Bull, AWS SQS.
Healthcare patient portal
Built a HIPAA-compliant Node.js backend with FHIR API, PostgreSQL, and encryption at rest. Passed third-party penetration test. Stack: NestJS, PostgreSQL, AWS EBS, Sentry.
Fintech payment processing
Developed a Node.js microservice for payment reconciliation with Plaid integration and idempotent API calls. Reduced transaction error rate to 0.02%. Stack: Express, Plaid, Redis, Kafka.
Social media feed API
Designed a high-throughput Node.js API with Elasticsearch for indexing and Kafka for event streaming. Delivered feeds with under 50ms response time for 1M users. Stack: Node.js, Elasticsearch, Kafka, AWS Lambda.
Why teams hire us.
Senior Node.js engineers only, no juniors
Every engineer on your project has 8+ years of Node.js experience. We do not train juniors on your time. You get a team that ships production-grade code from day one.
Fixed price, not hourly
After the Roadmap phase, you receive a fixed quote for the entire backend. No hourly billing means no surprise invoices. If we discover additional scope, we tell you before building.
Compliance built in (HIPAA, PCI, SOC 2)
Our Node.js backends are built with compliance as a default. We use encryption at rest and in transit, audit logging, and access control. 40% of our clients are in regulated industries.
Full code ownership from day one
When we finish a sprint, the code goes straight into your GitHub repository. You own every line. There is no lock-in, no proprietary boilerplate.
99.9% uptime SLA
We architect backends for high availability using load balancers, auto-scaling, and database replication. Our average production uptime across 200+ products is 99.9%.
Support even after launch
Every project includes 30 days of post-launch support with a 4-hour response SLA. We fix bugs, handle deployments, and answer questions from your team.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
