Node.js Development Case StudiesCase Studies
See exactly how we built production Node.js apps for startups and enterprises. Each case study shows the problem, the stack, and the outcome.
IRPR builds production-grade Node.js applications for startups and enterprises. We use Express, NestJS, Fastify, Prisma, Redis, RabbitMQ, and AWS Lambda to ship scalable backends. Every case study here represents a real project delivered on time and on budget.
Our Node.js MVPs ship in 8-12 weeks with fixed pricing from $80K to $250K. We handle HIPAA, PCI-DSS, SOC 2, and GDPR compliance. After launch, we provide ongoing DevOps and scaling support with 99.9% uptime SLAs.
Our clients are CTOs who need a proven backend partner, founders building their first API-driven product, and product managers replacing a legacy PHP or Ruby stack with Node.js. They hire IRPR to reduce risk and ship faster.

Node.js Development Case Studies by the Numbers
Our Node.js projects ship fast because we use battle-tested patterns and senior engineers.
We have delivered over 200 products across 50 countries. Every Node.js case study includes a measurable outcome, whether it is API response time improvement, cost reduction, or user growth.
Our average Node.js MVP ships in 12 weeks. Over 98% of our projects launch on time. We achieve 99.9% uptime for production backends running on AWS or GCP.
How IRPR Delivers Node.js Projects That Work
We are not a body shop. Every Node.js case study starts with a fixed price and a clear roadmap.
Generic agencies promise 'expertise' but hand your project to juniors. They bill hourly and extend timelines. We do the opposite.
IRPR assigns senior engineers only. We give you a fixed price in week 2 of the Roadmap phase. Our Node.js case studies show real outcomes like '50% faster API' or 'zero downtime during Black Friday'.
- Assigns junior developers
- Bills hourly with no cap
- No compliance expertise
- Delivers incomplete tests
- No post-launch support
- Code doesn't scale past 100K users
- Senior engineers only, 10+ years average
- Fixed price after Roadmap phase
- HIPAA, PCI-DSS, SOC 2, FERPA built in
- 100% test coverage for critical paths
- DevOps and monitoring included for 6 months
- Architected for millions of users
Our Node.js Development Process: From Idea to Production
Each case study follows the same repeatable process that reduces risk for your team.
We break every project into four phases. The Roadmap phase costs a fixed $5K and takes 1-2 weeks. You get a detailed spec and exact price before we write a line of code.
After the roadmap, we build your MVP in 8-12 weeks. Then we release it to your users and provide 6 months of ongoing DevOps and monitoring.
What Ships with Every Node.js Project
Every case study project includes these deliverables. No hidden extras.
We believe in shipping production-quality code from day one. Your team gets everything needed to run and maintain the Node.js backend after launch.
- Full source code in your private GitHub repo
- CI/CD pipeline using GitHub Actions or CircleCI
- Automated tests with Jest, Supertest, and Cypress
- Sentry error tracking with performance monitoring
- Prometheus + Grafana dashboards for metrics
- Swagger or GraphQL Playground documentation
- Docker Compose for local development
- Terraform scripts for AWS/GCP provisioning
- Runbook with deployment and recovery steps
- 6 months of DevOps support
What we ship in this practice.
Real-time analytics dashboard for a fintech startup
Built a Node.js backend using Express, WebSocket, and Redis Streams to stream transaction data to a live dashboard. Reduced data latency from 15 seconds to under 200ms. Handles 10M+ events per day. Stack: Node.js, PostgreSQL, Redis, AWS Fargate.
HIPAA-compliant patient messaging platform
Developed a secure messaging API with Node.js, Express, and AES-256 encryption. Integrated with Epic and Cerner EHRs. Passed HIPAA audit on first submission. Supports 500+ concurrent providers. Stack: Node.js, PostgreSQL, Twilio, AWS KMS.
Headless e-commerce backend for a multi-brand retailer
Built a Node.js backend with NestJS, Prisma, and Stripe Connect that manages inventory across 12 brands. Replaced a monolithic Magento system. Reduced page load time by 60%. PCI-DSS Level 4 compliant. Stack: NestJS, PostgreSQL, Redis, Stripe, Vercel.
Microservices platform for a real estate SaaS
Architected a set of 8 Node.js microservices with RabbitMQ, Docker, and Kubernetes. Each service handled a domain: listings, users, tours, payments. Reduced deployment time from 2 hours to 5 minutes. Stack: Node.js, Express, RabbitMQ, PostgreSQL, Kubernetes.
Serverless video processing API for EdTech
Created a serverless Node.js backend on AWS Lambda that transcodes, captions, and streams educational videos. Uses FFmpeg on Lambda layers and DynamoDB for metadata. Onboarded 50K students in the first month. Stack: Node.js, AWS Lambda, DynamoDB, S3, CloudFront.
GraphQL API for a manufacturing IoT platform
Built a GraphQL API with Apollo Server and Prisma that aggregates sensor data from 2,000+ machines. Real-time alerts via WebSocket. Reduced report generation time from 3 hours to 12 minutes. Stack: Node.js, Apollo Server, GraphQL, PostgreSQL, InfluxDB, MQTT.
Why teams hire us.
Fixed price, not hourly billing
Every Node.js project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we start building.
Senior engineers only
Our team averages 10+ years of Node.js experience. No junior developers. Every engineer has shipped production Node.js apps handling millions of requests. You get a senior architect on every project.
Compliance built-in from day one
We embed HIPAA, PCI-DSS, SOC 2, and GDPR controls in the architecture, not as an afterthought. Our Node.js case studies include audit-ready setups for regulated industries.
Proven methodology: Idea to release in 8-12 weeks
Our 4-phase process (Idea, Roadmap, Product, Release) has shipped over 200 Node.js products. Every phase ends with a deliverable you can review and approve.
Full test coverage and DevOps included
We deliver 100% test coverage for critical paths, CI/CD pipelines, Sentry error tracking, and 99.9% uptime SLAs. Your team gets a production-ready backend, not a prototype.
You own all the code
The source code, infrastructure scripts, and documentation are yours. We never use proprietary frameworks. You can take the project in-house or to another vendor at any time.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
