Senior Node.js App Development DevelopersDevelopers
We build production-ready Node.js apps in 12 weeks. Fixed pricing, senior engineers only — no hourly billing.
IRPR connects you with senior Node.js app development developers who build production-grade applications using Node.js, Express, TypeScript, and PostgreSQL. Every engineer has 5+ years of Node.js experience and has shipped apps for startups and Fortune 500s.
We deliver a fully functional MVP in 8-12 weeks with a fixed price between $80,000 and $250,000. All projects include automated testing, CI/CD pipelines, and compliance with HIPAA, PCI-DSS, or SOC 2 if required.
CTOs who need to scale engineering capacity without hiring. Founders who want a working prototype to raise funding. Product managers augmenting an in-house team for a critical Node.js backend. We work async-first but maintain daily syncs across US time zones.
Types of software we ship.
REST API development
Design and build scalable REST APIs with Node.js, Express, and PostgreSQL. Includes OpenAPI documentation and rate limiting.
GraphQL backend
Implement a GraphQL server with Apollo or TypeGraphQL. Perfect for complex data models and real-time subscriptions.
Real-time chat application
Build WebSocket-powered chat using Socket.io and Redis. Handles thousands of concurrent connections with message persistence.
Microservices architecture
Break monolithic apps into Node.js microservices with Docker, Kubernetes, and message queues like RabbitMQ.
Serverless functions
Deploy AWS Lambda functions with Node.js 20. Integrate with API Gateway, S3, and DynamoDB for event-driven workflows.
Webhook integration pipeline
Create a reliable webhook receiver and sender system using Node.js. Handles retries, logging, and authentication via HMAC.
Data processing pipeline
Process large files and streams with Node.js streams and Bull queues. Includes error handling and progress tracking.
Admin panel backend
Build the backend for admin dashboards with Node.js, Express, and JWT authentication. Supports role-based access and audit logs.
We build for every business type.
Senior Node.js App Development Developers deliver measurable results
Every project ships with proven metrics from our portfolio of 200+ Node.js applications.
Our senior Node.js developers have built everything from payment processing APIs processing $50M/year to real-time dashboards serving 100,000 daily users. We track every project against time, cost, and quality benchmarks.
With a 12-week average timeline and 98% on-time delivery, IRPR ensures your Node.js app development stays predictable. You get a fixed price quote after the 2-week Roadmap phase, and we never exceed it.
Our Node.js development process is different by design
Most agencies assign junior developers and bill by the hour. We do the opposite.
Generic dev shops hire cheap talent and hope for the best. You end up with a tangled codebase, missed deadlines, and a surprise bill at the end. Our senior Node.js app development developers work on retainer-grade architecture from day one.
IRPR builds with a fixed price, senior-only team, and a clear architecture blueprint delivered in week 2. You review the plan, approve the price, and then we build. No scope creep, no hidden fees.
- Hourly billing with unpredictable costs
- Junior developers fresh from bootcamps
- No architecture documentation
- Slow response times across time zones
- You don’t own the repository
- Manual testing, if any
- Fixed price per project, no surprises
- Senior engineers with 5+ years Node.js
- Architecture blueprint delivered in week 2
- Daily standups with US overlap
- Full source code transferred to your GitHub
- Automated CI/CD with 95% test coverage
How we build your Node.js app in 12 weeks
Our four-phase process moves from discovery to production, with milestones at every step.
The Roadmap phase (week 1-2) locks in scope, architecture, and price. After you approve, we enter two-month development sprints. Each sprint delivers a deployable increment.
Final deployment includes infrastructure setup on AWS or GCP, CI/CD configuration, and a one-month free maintenance period.
What ships with your Node.js project
Every project includes a production-ready software package, not just code.
When IRPR delivers, you get more than a running backend. We ship everything needed to maintain and scale the application independently.
- Source code in your private GitHub repository
- CI/CD pipeline with GitHub Actions and automated tests
- Postman collection for every API endpoint
- OpenAPI 3.0 documentation (Swagger UI)
- Docker Compose configuration for local development
- Unit and integration tests with 90%+ coverage
- Deployment scripts for AWS ECS or similar
- Sentry error tracking and Datadog monitoring
- Database migration scripts (TypeORM or Prisma)
- 30-day post-launch support and bug fixes
What we ship in this practice.
Real-time analytics dashboard for ecommerce
Built a Node.js backend with WebSocket streaming and Redis caching to serve live sales metrics. Reduced data refresh time from 60 seconds to under 1 second. Tech stack: Node.js, Express, Socket.io, Redis, PostgreSQL.
Payment processing API for a fintech startup
Developed a PCI-DSS compliant API integrating Stripe and Plaid for subscription billing. Processed $5M in transactions within the first month with 0 chargebacks. Tech stack: Node.js, TypeScript, Stripe, Plaid, PostgreSQL.
Microservices migration for a logistics company
Broke a monolithic Node.js app into 12 microservices with Docker and Kubernetes. Cut deployment time from 4 hours to 10 minutes. Tech stack: Node.js, Docker, Kubernetes, RabbitMQ, MongoDB.
HIPAA-compliant backend for a healthtech SaaS
Created a secure Node.js backend managing patient health records. Achieved HIPAA compliance with PHI encryption, audit logs, and BAA. Helped the client raise $200K seed funding. Tech stack: Node.js, HAPI, PostgreSQL, AWS.
Video streaming backend for a media company
Built a Node.js pipeline for video transcoding and delivery using FFmpeg and AWS S3. Delivered 50,000 hours of video per month to users worldwide. Tech stack: Node.js, FFmpeg, AWS Lambda, S3, CloudFront.
Real-time chat app for real estate platform
Implemented Socket.io chat with typing indicators, read receipts, and message history. Handled 10,000 concurrent users on a single instance. Tech stack: Node.js, Socket.io, Redis, PostgreSQL.
Why teams hire us.
Senior-only teams, no juniors
Every engineer on your project has at least 5 years of Node.js experience. We don’t apprentice on client projects. Our average engineer has shipped 15+ production apps.
Fixed price, not hourly
You get a fixed price quote after week 2. No hourly billing, no scope creep charge, no surprise invoices. The price we quote is the price you pay.
Production-ready code, not a prototype
We ship with automated CI/CD, monitoring (Datadog, Sentry), and 90% test coverage. Your code is ready for production traffic on day one.
Full code ownership
Every line of code belongs to you. We deliver source code in your GitHub repository with a permissive license. No licensing fees, no lock-in.
12-week delivery guarantee
Our process is optimized for speed. 98% of projects complete on time. If we miss the target, we fix the issues at no extra cost.
Post-launch support included
You get 30 days of free bug fixes and minor adjustments after deployment. We stay on Slack for priority issues during that window.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
