Best Node.js App Development ServicesApp Development
We build production-ready Node.js applications for startups and enterprises. Ship in 8-12 weeks with a fixed price and full code ownership.
IRPR builds high-performance Node.js applications using Express.js, NestJS, and Fastify for API development, with React or Next.js on the frontend. We deploy on AWS Lambda or EC2 with Docker and CI/CD pipelines.
Every project includes source code in your Git repo, automated testing with Jest and Cypress, and a CI/CD pipeline on GitHub Actions. Timeline is 8-12 weeks for an MVP, with pricing from $80K to $250K. We handle compliance for HIPAA, PCI-DSS, SOC 2 as needed.
CTOs at funded startups who need a scalable backend, product managers replacing legacy PHP or Python systems, and enterprise teams requiring real-time data processing. Also, founders launching SaaS platforms who want a reliable Node.js backend.

Why Node.js is the right choice for your backend
Node.js delivers performance, scalability, and a massive ecosystem.
Node.js uses an event-driven, non-blocking I/O model that handles 10,000+ concurrent connections with a single server. It is built on Chrome's V8 engine, making it faster than Python or Ruby for most use cases.
With npm, Node.js gives you access to over 2 million packages, accelerating development. Companies like Netflix, Uber, and LinkedIn use Node.js for its speed and scalability.
Why IRPR beats generic dev shops for Node.js projects
Most agencies overpromise and underdeliver. IRPR ships on time with fixed prices.
Generic dev shops often start coding without a clear roadmap, leading to scope creep and missed deadlines. They use junior developers and mark up hourly rates.
IRPR starts with a 2-week Roadmap phase where we define every API endpoint, database schema, and deployment plan. You get a fixed price quote before any code is written.
- Starts coding without specification
- Uses variable rates and hourly billing
- Assigns junior or offshore developers
- Delivers late or over budget
- No CI/CD or automated testing
- Code ownership unclear
- 2-week Roadmap phase with full specification
- Fixed price quote before development
- Senior developers with 10+ years experience
- 8-12 week delivery with 98% on-time rate
- CI/CD pipeline with Jest, Sentry, and Docker
- Full code ownership from day one
Our Node.js development process in 4 phases
From idea to production, we follow a repeatable 4-phase system.
Phase 1: Idea validation and architecture planning. We map out the product strategy, choose the right Node.js framework (Express, NestJS, or Fastify), and define the data model.
Phase 2: Roadmap creation. We write user stories, design the database schema, and create a detailed technical specification. You approve the plan before any code is written.
What you get with every Node.js project at IRPR
Every deliverable is concrete and ready for production.
Every project includes a fully functional Node.js backend deployed on AWS or your own server. You get the source code in your GitHub repo with a CI/CD pipeline already running.
We also ship a Postman collection or OpenAPI spec for your APIs, plus a monitoring dashboard on Sentry and New Relic. Your team inherits complete documentation and deployment scripts.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Automated tests with Jest and Cypress (90%+ coverage)
- API documentation via Swagger or Postman
- Docker containerization for easy deployment
- Sentry error tracking and New Relic performance monitoring
- Database schema and migration scripts
- Deployment playbook and runbook
- 30 days of post-launch support
- Full production deployment on AWS/GCP/Azure
What we ship in this practice.
