Our Node.js backend expertise in numbers
We build systems that ship fast and stay reliable.
Our team has completed 200+ Node.js projects over 7 years. Average delivery is 10 weeks from spec to deploy.
We maintain a 98% on-time delivery rate and a 4.9/5 client satisfaction score. Our backends handle over 500M API calls monthly.
Why senior Node.js developers matter
Most development shops assign junior devs to your backend. We don't.
Generic dev shops often cut costs by using mid-level or junior Node.js engineers. You get slower delivery, technical debt, and undocumented code.
IRPR assigns senior engineers with 8+ years of Node.js experience. Every line of code is reviewed, tested, and documented. You get a production-ready backend in 8-12 weeks.
- Junior or mid-level developers
- Hourly billing with no cap
- No dedicated project manager
- Code is rarely documented
- No CI/CD or monitoring setup
- Security compliance is extra cost
- Senior Node.js engineers (8+ yr avg)
- Fixed price from Roadmap phase
- Dedicated PM and technical lead
- Full documentation (API docs, Swagger)
- CI/CD pipeline (GitHub Actions, Sentry)
- HIPAA, PCI-DSS, SOC 2 included
How we build your Node.js backend
Four phases from concept to deployment.
Our process starts with a 2-week Roadmap where we define the API schema, data model, and infrastructure. You get a fixed quote and a timeline.
We then build the product in 6-9 sprints, deploy to staging, and run load testing. Final release includes migration to production and monitoring setup.
What ships with your Node.js backend
No surprises. Everything listed here is included.
Every project includes source code in your private GitHub repo, a fully configured CI/CD pipeline on GitHub Actions, and a staging environment on AWS or GCP.
We also deliver Swagger/OpenAPI documentation, a Postman collection for testing, and a comprehensive deployment guide.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Staging environment on AWS or GCP
- Swagger/OpenAPI documentation
- Postman collection for API testing
- Unit and integration tests (80%+ coverage)
- Sentry error tracking and performance monitoring
- Database migration scripts (Node.js migrations)
- Docker Compose for local development
- Deployment guide and runbooks
What we ship in this practice.
Subscription billing API for SaaS
Built a Stripe-integrated Node.js API that handles 50K+ billing events per month. Reduced failed payment retries by 90% using automated dunning. Tech stack: Node.js, Stripe, PostgreSQL, BullMQ.
Real-time chat backend for health platform
Delivered a HIPAA-compliant chat backend using Socket.io and MongoDB. Supports 10K concurrent users with message encryption at rest and in transit. Tech stack: Node.js, Socket.io, MongoDB, AWS KMS.
Payment gateway microservice for fintech
Built a PCI-DSS compliant payment processing service that handles 100K transactions daily. Integrated with multiple acquirers (Stripe, Adyen) and added fraud detection scoring. Tech stack: Node.js, Express, Adyen, Redis, Docker.
Inventory API for ecommerce marketplace
Created a scalable inventory management API using Node.js and Elasticsearch. Handles 2M SKUs with real-time stock updates across 50+ warehouses. Reduced inventory sync latency from 5 minutes to 3 seconds.
Notification engine for logistics platform
Developed a multi-channel notification service (email, SMS, push) for delivery updates. Processes 500K+ notifications daily with 99.9% delivery rate. Tech stack: Node.js, Twilio, SendGrid, AWS SQS.
API gateway for media streaming service
Built an API gateway that routes requests to 12 microservices, handles rate limiting, and caches responses. Reduced average response time from 200ms to 45ms. Tech stack: Node.js, Fastify, Redis, AWS API Gateway.
Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote after the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. Average backend project costs $80K-$250K.
Senior engineers only
Our team averages 8+ years of Node.js experience. We never outsource or use junior developers. Each project is led by an engineer who has shipped 10+ production backends.
Compliance built in
We handle HIPAA, PCI-DSS, and SOC 2 compliance as part of the standard build. No separate audits or add-ons. Our backends pass security reviews on first submission.
Full code ownership
You own all source code, documentation, and infrastructure from day one. We transfer private GitHub repos, Docker images, and cloud accounts on release.
8-12 week delivery
We ship production-ready backends in 8-12 weeks using agile sprints. Our average on-time delivery rate is 98% across 200+ projects.
Post-release support included
Every project includes 2 weeks of hyper-care after release where we monitor, fix issues, and optimize. Optional ongoing support at $5K/month retainer.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
