Why Choose a Professional Node.js App Development Firm
IRPR delivers production-ready Node.js applications with predictable timelines and costs.
Our team of senior Node.js engineers has shipped over 200 products across 50 countries. We focus on clean, maintainable code and automated testing from day one.
Each project follows a structured roadmap: discovery, architecture, sprint cycles, and release. We use GitHub Actions for CI/CD, Sentry for error tracking, and Datadog for monitoring.
How IRPR Differs from Generic Development Shops
Most agencies overpromise and underdeliver. IRPR fixes that.
Generic shops use junior developers, charge hourly, and disappear after launch. They hand off unmaintainable code with no documentation.
IRPR assigns senior engineers only, works on a fixed price, and includes ongoing support. All code is documented, tested, and deployed with CI/CD.
- Junior developers learn on your project
- Hourly billing with no budget cap
- No code documentation or tests
- Post-launch support costs extra
- Unclear milestones and timelines
- No compliance or security expertise
- Senior Node.js engineers only (6+ years experience)
- Fixed price from roadmap (week 2)
- Full test coverage and typed documentation
- 2-week support window included post-launch
- 2-week sprint cycles with weekly demos
- HIPAA, SOC 2, PCI-DSS compliance built in
Our Node.js App Development Process
From idea to production in 8-12 weeks.
We start with a discovery sprint to define architecture and data flow. Then we build in 2-week iterations, delivering working software every sprint.
Your team gets daily access to the repo, automated deployments, and a staging environment. We handle infrastructure as code and security hardening.
What Ships with Your Node.js Application
Every deliverable includes the following by default.
No hidden handoffs. You get everything needed to run and extend your Node.js app.
- Source code in your private GitHub repository
- CI/CD pipeline with GitHub Actions and automatic deployments
- Sentry error tracking and Datadog monitoring configured
- Comprehensive test suite (unit, integration, e2e)
- API documentation (Swagger/OpenAPI) for all endpoints
- Infrastructure as code (Terraform or Pulumi scripts)
- Docker containers for local development and production
- Post-launch support for 2 weeks (bug fixes and tweaks)
- Engineering handoff session and architecture walkthrough
- One year of hosting recommendations and scaling plan
What we ship in this practice.
Real-time Chat Platform Backend
Built a WebSocket-based chat backend handling 10,000 concurrent connections using Node.js, Socket.io, and Redis. The client reduced latency from 500ms to under 50ms.
Multi-Tenant SaaS Backend
Developed a multi-tenant Node.js backend for a billing SaaS using Nest.js, PostgreSQL, and Stripe. Enabled the client to onboard 50 new enterprise customers in 3 months.
E-commerce Order Processing Service
Created a microservice for order processing handling 5,000 orders/day with Node.js, Bull queues, and MongoDB. Cut order fulfillment time by 40%.
HIPAA-Compliant Patient Data API
Built a Node.js API for patient health records with end-to-end encryption, audit logs, and FHIR integration. Achieved HIPAA compliance audit in 2 weeks.
Fintech Payment Reconciliation Engine
Engineered a Node.js reconciliation service that matches 100,000+ transactions daily using Express, PostgreSQL, and AWS Lambda. Reduced manual reconciliation from 20 hours to 2 hours per week.
Real Estate MLS Data Aggregator
Developed a Node.js data pipeline that aggregates MLS listings from 10 sources into a unified API. The client saw a 300% increase in data freshness.
Why teams hire us.
Senior Engineers Only
Every project is staffed with Node.js engineers who have a minimum of 6 years of experience. No junior developers, no training wheels.
Fixed Price from Week 2
After the Roadmap phase, we lock in a fixed price for the entire project. No hourly billing, no surprise invoices, no scope creep charges.
8-12 Week MVPs
Most of our projects deliver a production-ready MVP in 8 to 12 weeks. We have a 98% on-time delivery rate across all projects.
Compliance Built In
We bake HIPAA, SOC 2, PCI-DSS, and FERPA compliance into the architecture from day one. No retrofitting security later.
Full Code Ownership
You own all source code, IP, and documentation. We transfer repos to your GitHub organization immediately upon launch.
Post-Launch Support Included
Every project includes 2 weeks of post-launch support for bug fixes and adjustments. We also provide a one-year hosting and scaling recommendation.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
