Best Node.js Backend Development ConsultantsDevelopment Consultants
We build production-grade Node.js APIs and microservices. Fixed price, on time, owned by you.
IRPR is a team of senior Node.js engineers who build backend systems for companies that need reliability at scale. We use Express.js, Fastify, NestJS, PostgreSQL, Redis, and AWS Lambda to ship APIs and microservices that handle millions of requests per day.
Most projects start with a 2-week Roadmap phase for a fixed fee of $3,500. Full builds run 8 to 12 weeks and cost $60,000 to $200,000. Every project ships with CI/CD, automated tests, and monitoring. Code is fully owned by you.
Our clients are CTOs at growing SaaS companies who need to refactor a monolithic backend, founders launching a data-intensive MVP that must pass SOC 2 from day one, and engineering leads at fintech firms who need a PCI-compliant Node.js payment gateway built in under 10 weeks.

Why Node.js backend consultants outperform in-house hires
Senior Node.js consultants ship faster because they bring battle-tested patterns from dozens of production systems.
IRPR has built backend systems for over 200 products. Every project starts with a fixed-price Roadmap where we design the data model, select the database (PostgreSQL, MongoDB, or DynamoDB), and diagram the auth flow. By week 2, you see a complete architecture document, not just a Gantt chart.
Our consultants have built Node.js backends that handle 50,000 requests per second, process 1 million messages per minute through RabbitMQ, and maintain 99.9 percent uptime under load. We use the same patterns across projects so we don't learn on your dime.
The difference between generic shops and IRPR consultants
Not all Node.js consultants are equal. Here is how IRPR separates from agencies that offshore work or burn hours.
Generic dev shops often assign junior developers to your project, bill by the hour with no cap, and hand over uncommented code with no deployment pipeline. Their Node.js backends frequently fail during peak traffic because they skipped load testing.
IRPR assigns senior engineers with 8+ years of Node.js experience. We work in 12-week sprints with fixed pricing. Every project ships with a complete CI/CD pipeline on GitHub Actions, automated test coverage above 80 percent, and Sentry error monitoring already configured.
- Junior or mid-level developers
- Hourly billing with no budget cap
- No architecture document upfront
- No CI/CD pipeline at handoff
- Test coverage below 40 percent
- No production monitoring
- Senior engineers only (8+ years Node.js)
- Fixed price agreed in Roadmap phase
- Complete data model and API contract in week 2
- GitHub Actions CI/CD from day one
- Test coverage above 80 percent
- Sentry and Datadog configured before deployment
Our 4-phase Node.js backend consulting process
Every engagement follows the same proven structure: Idea, Roadmap, Product, Release.
We do not start coding in week 1. The Roadmap phase (weeks 1-2) produces a detailed architecture document with database schema, API endpoints, authentication strategy, and deployment plan. This phase costs $3,500 and is fully refundable if you decide not to proceed.
The Product phase (weeks 3-12) is where we build your backend. We use TypeScript throughout, write integration tests for every endpoint, and deploy to a staging environment by week 6. The Release phase includes performance load testing, security audit, and production deployment.
What ships with every Node.js backend project
Every delivery includes production infrastructure, not just code.
When IRPR finishes a Node.js backend project, you do not get a zip file. You get a running production system with monitoring, error tracking, and a CI/CD pipeline that your team can use immediately. No configuration required.
We also include a handover session with your engineering team where we walk through the codebase, explain the deployment process, and show how to add new endpoints. Your team can start shipping features within 48 hours of handoff.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Automated test suite with Jest and Supertest
- API documentation via Swagger or Postman
- Docker Compose for local development
- Production Docker image on AWS ECR
- Sentry error tracking and alerts
- Datadog APM and infrastructure monitoring
- Deployment playbook and runbook
- One-week knowledge transfer session
What we ship in this practice.
Healthcare appointment scheduling API
Built a HIPAA-compliant Node.js API for a telehealth startup. The system processes 8,000 appointments daily, integrates with Twilio for SMS reminders, and stores data in PostgreSQL with row-level security. Reduced scheduling errors by 95 percent.
Fintech payment processing microservice
Designed a PCI-DSS compliant payment microservice using NestJS and Stripe. Handles 2,000 transactions per minute, with idempotency keys to prevent duplicate charges. Paved the way for SOC 2 certification in 5 weeks.
SaaS multi-tenant data dashboard backend
Built a multi-tenant Node.js backend with Express.js and MongoDB for a marketing analytics SaaS. Each tenant gets isolated data via collection prefixes. The system ingests 10 million events per day from Segment and Mixpanel.
Real estate MLS data aggregator
Created a Node.js ETL pipeline that pulls property data from 12 MLS providers every 15 minutes, normalizes it, and serves via a Fastify API. Reduced data latency from 6 hours to 15 minutes.
Ecommerce inventory sync service
Developed a real-time inventory sync service with RabbitMQ that connects Shopify, Amazon, and a warehouse WMS. Eliminated overselling completely. Syncs 50,000 SKUs per hour.
EdTech real-time collaboration backend
Built a WebSocket backend with Socket.IO and Redis for a classroom collaboration platform. Supports 500 concurrent rooms with latency under 200ms. Integrated with Google Classroom via OAuth.
Why teams hire us.
Fixed price, not hourly billing
Every Node.js backend project gets a fixed quote during the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. The price you see is what you pay.
Senior engineers only, no juniors
IRPR does not hire junior developers. Every consultant has 8 plus years of Node.js experience and has built at least 3 production backends from scratch. No training, no on-the-job learning.
Full code ownership from day one
You own every line of code, every Dockerfile, every CI/CD configuration. We never lock you into a platform. Transfer the repo to your team the day we ship.
Start in 2 weeks, not 2 months
Most new engagements begin within 14 calendar days. We kick off with the Roadmap phase and have a working staging environment by week 6. No extended scoping calls.
Built for compliance from the start
We bake HIPAA, PCI-DSS, SOC 2, and GDPR requirements into the architecture from day one. No expensive retrofitting. We have shipped compliant Node.js backends for 20 plus regulated companies.
Production monitoring included
Every project ships with Sentry error tracking, Datadog APM, and PagerDuty alerts. You know when things fail before your customers do. This is not an upsell; it is included in the fixed price.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
