Node.js Development ConsultantsDevelopment Consultants
Hire senior Node.js consultants who ship production systems in 8-12 weeks. Fixed pricing with no surprise invoices.
IRPR builds production Node.js backends, APIs, and full-stack applications for companies worldwide. Our consultants use Express, NestJS, Next.js, and PostgreSQL to ship high-throughput systems that handle millions of requests per day.
Projects ship in 8-12 weeks with a fixed price between $80K and $250K. Every system meets compliance standards like HIPAA (healthcare), PCI-DSS (payments), and SOC 2 (SaaS). We deliver source code, CI/CD, and documentation on day one of the launch.
Startup CTOs hire us to build their MVP without hiring a full team. Enterprise engineering managers bring us in for architecture redesigns or microservices migration. SaaS founders use us to add scalable API tiers and payment integrations. Each engagement starts with a paid Roadmap phase (week 2) that locks the scope and price.

Why companies hire Node.js development consultants
Node.js is the backbone of modern API-first products, and IRPR delivers production-grade systems in weeks.
Our consultants have shipped over 200 Node.js projects for companies across 50 countries. We build everything from REST APIs handling 100k requests/second to real-time collaboration tools serving 10k concurrent users. Every project ships with a complete CI/CD pipeline on GitHub Actions and monitoring through Sentry and DataDog.
We use a fixed price model that starts after a two-week Roadmap phase. During Roadmap, we write a detailed technical specification with wireframes, data models, and API contracts. The price and timeline are locked at the end of week 2. No hourly billing. No scope creep.
Generic dev shop vs IRPR Node.js development consultants
Most agencies assign junior developers and bill by the hour. IRPR gives you senior Node.js experts on a fixed price.
Generic shops often start with a vague proposal, assign developers from a bench, and charge for every email ping. You get a Node.js backend that works but has no tests, no CI/CD, and no scalability planning. Budgets balloon when you ask for a simple API endpoint.
IRPR assigns a lead architect (10+ years Node.js), a senior backend engineer, and a QA specialist to every project. We write integration tests, set up GitHub Actions, and deploy on AWS ECS or Lambda from day one. The price is fixed after the Roadmap phase, and you own the code.
- Hourly billing with no cap
- Junior engineers working on your code
- No test automation or CI/CD setup
- Unclear scope leading to change orders
- No compliance knowledge (HIPAA, PCI)
- No post-launch support plan
- Fixed price locked in week 2
- Senior Node.js engineers (10+ years)
- Full CI/CD (GitHub Actions, Sentry, Docker)
- Detailed spec from Roadmap phase
- HIPAA / PCI-DSS compliance built in
- 12 weeks of post-launch support included
How we work with Node.js development consultants
Our four-phase process ensures your Node.js project ships on time and on budget.
Phase 1 (Idea, week 1): We align on your product vision, user stories, and success metrics. You talk directly to a senior consultant who has built 20+ Node.js backends.
Phase 2 (Roadmap, week 2): We create a complete technical specification: data models, API contracts, deployment architecture, and a fixed price. You sign off on the spec and we start building.
What ships with every Node.js development engagement
Every project delivers more than just code. You get the entire production environment and documentation.
When IRPR ships a Node.js project, you receive a complete production system including automated tests, monitoring, and deployment scripts. Our consultants write everything in ES2022 and follow SOLID principles.
We also include a post-launch support period where we handle bug fixes, performance tuning, and minor feature additions. The code is fully owned by your company.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions and Docker
- Automated API tests (Jest, Supertest)
- Sentry error tracking and performance monitoring
- Infrastructure as code (Terraform, AWS CDK)
- API documentation (Swagger/OAS 3.0)
- Production deployment on AWS ECS or Lambda
- Database migrations and seed scripts
- Runbook with incident response procedures
- Post-launch support for 12 weeks
What we ship in this practice.
Real-time Collaboration Dashboard
Built a WebSocket-powered dashboard for a logistics company. The Node.js backend processes 50k location updates per second using Redis Streams and Socket.IO. Reduced report generation time from 4 hours to 3 minutes.
HIPAA-Compliant Telemedicine API
Developed a Node.js backend for a telehealth startup. Integrated with Twilio Video and Epic EHR via FHIR. Achieved HIPAA compliance with encryption at rest and in transit. Shipped in 10 weeks at fixed price.
Subscription Billing Engine for SaaS

Fixed price, not hourly billing
Every Node.js project gets a fixed quote after the two-week Roadmap phase. No time trackers, no surprise invoices. The price you see is the price you pay.

You own all source code, infrastructure scripts, and documentation. No monthly royalties, no IP restrictions. We push code to your repo from day one.
Compliance built-in (HIPAA, PCI-DSS, SOC 2)
Our Node.js consultants build with compliance from the start. We implement encryption, audit logs, and access controls required for healthcare, payments, and enterprise SaaS.
Post-launch support included
You get 12 weeks of post-launch coverage with a 4-hour response SLA. We fix bugs, tune performance, and help your team take over the codebase.
Idea → Roadmap → Product → Release.
