Custom Node.js Backend Development FirmBackend Development
We build production-grade Node.js backends that scale. 12 weeks from spec to deploy, fixed price.
IRPR builds custom Node.js backend development for startups, scale-ups, and enterprises. We use Express, NestJS, GraphQL, and Socket.io to create APIs, microservices, and real-time systems that handle millions of requests.
Every project ships with full source code, CI/CD pipelines, and monitoring. Typical timeline is 8-12 weeks. Fixed pricing starts at $80K and goes to $250K depending on scope. We comply with HIPAA, PCI-DSS, and SOC 2 standards.
We work with CTOs who need a custom Node.js backend to support a new SaaS product, enterprise architects migrating monolithic apps to microservices, product owners who want a scalable API for mobile or web, and engineering managers requiring a backend refactor with zero downtime.
Types of software we ship.
REST API Development
Build stateless REST APIs with Express or Fastify. Supports JWT, rate limiting, and OpenAPI docs.
GraphQL API Development
Create type-safe GraphQL backends using Apollo Server or Yoga. Integrates with PostgreSQL, Redis, and REST sources.

Custom Node.js Backend Development Firm by the Numbers
We don't just code Node.js backends. We ship production systems that stay up and scale.
IRPR has delivered over 200 Node.js backend projects across 50 countries. Our engineers average 12+ years of experience. Every project goes through a structured build phase with weekly demos and a fixed budget.
Our on-time delivery rate is 98%. We use automated testing, code reviews, and load testing before every release. If we miss a deadline, you get a discount on the next phase -- but that hasn't happened in the last 50 projects.
Why IRPR for Your Custom Node.js Backend
Most dev shops bill hourly and scope creep. We do the opposite.
Typical agencies start with a vague estimate, then charge extra when requirements change. They use junior developers and hand off the project after launch. You end up with code you don't own and a system that doesn't scale.
IRPR gives you a fixed price after a 2-week Roadmap phase. Senior engineers only. You own all the code from day one. We set up monitoring, CI/CD, and documentation as part of the standard package.
- Hourly billing with no cap
- Junior or mixed-seniority teams
- Deliverables often miss the mark
- No DevOps or monitoring included
- Scope changes = cost overruns
- Documentation is an afterthought
- Fixed price after 2-week Roadmap
- Senior engineers only (12+ yr avg)
- Weekly demos and sign-offs
- CI/CD, Sentry, and CloudWatch included
- Scope changes quoted separately, never surprise
- Full documentation and runbooks
How We Build Your Custom Node.js Backend
A repeatable process that de-risks your investment from day one.
We start with a 2-week Roadmap phase. Our engineers analyze your requirements, define the architecture, and produce a fixed-price proposal. You approve the plan before any coding begins.
Then we build in 2-week sprints. Each sprint ends with a demo of a working backend. By week 8-12 you have a production-ready system with tests, docs, and monitoring.
What Ships With Your Node.js Backend
No hidden costs or missing pieces. Everything below is included.
When we finish the project, you get more than just code. You get a fully deployable system with all the tooling a senior engineer would set up for production. No extra purchase orders needed.
We include 30 days of post-launch support for any issues. After that, we can set up a maintenance retainer or you hand the code to your own team.
- Source code in your own GitHub/GitLab repo
- CI/CD pipeline via GitHub Actions or GitLab CI
- Automated test suite (unit + integration)
- API documentation (OpenAPI or GraphQL schema)
- Production monitoring with Sentry and CloudWatch
- Database schema migration scripts
- Docker Compose for local development
- Environment configuration (.env template)
- Post-launch support for 30 days
- Readme and runbook for operations
What we ship in this practice.
SaaS subscription backend
Built a multi-tenant Node.js backend with Stripe billing, usage-based pricing, and webhook handling. Reduced billing errors by 90% using idempotency keys. Stack: Express, PostgreSQL, Redis.
Real-time logistics API
Developed a real-time tracking system with Socket.io and Mapbox. Handled 500 concurrent driver updates per second. Improved ETA accuracy by 35%. Stack: NestJS, MongoDB, Redis.
Healthcare data pipeline
Created an HL7-to-Node.js ingestion pipeline for a telehealth platform. Processed 10,000 records daily with full HIPAA logging. Stack: Bull queues, PostgreSQL, AWS Lambda.
Fintech payment gateway
Built a PCI-DSS compliant payment API with tokenization and Stripe Connect sub-merchants. Achieved 99.99% uptime over 12 months. Stack: Express, TypeScript, AWS RDS.
Ecommerce product feed engine
Designed a microservice that aggregates product data from 20+ suppliers into a normalized API. Reduced data synchronization time from 4 hours to 15 minutes. Stack: Node.js, RabbitMQ, Elasticsearch.
Mobile app backend for field service
Built a Node.js backend with offline sync, push notifications, and job scheduling for 1,000 field technicians. Offline mode handled 5,000 transactions before sync. Stack: Socket.io, MongoDB, Firebase Cloud Messaging.
Why teams hire us.
Fixed price, not hourly
Every custom Node.js backend development project gets a fixed quote after a 2-week Roadmap. No hourly billing, no surprise invoices. You know the cost up front.
Senior engineers only
Every developer on your project has 12+ years of experience. No junior devs learning on your dime. You get a lead engineer who architects and builds the entire backend.
Full code ownership
You own every line of code from day one. We push to your repo, not ours. No licensing fees, no vendor lock-in.
Compliance baked in
We build backends that pass HIPAA, PCI-DSS, and SOC 2 audits. If your industry requires compliance, we handle the logging, encryption, and access controls from the start.
12-week delivery guarantee
Our standard timeline is 8-12 weeks for a production-ready backend. If we deliver late, you get a discount on the next phase. We have a 98% on-time record.
Integrated DevOps from sprint one
Every project ships with CI/CD, automated tests, monitoring, and error tracking. No separate DevOps team needed. We deploy to AWS, GCP, or Azure.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
