Why choose an experienced Node.js app development agency
IRPR has shipped over 200 Node.js projects for clients in 50 countries.
An experienced Node.js app development agency brings more than code. We bring architecture decisions that scale. For example, we choose PostgreSQL with proper indexing over MongoDB for relational data. We use Redis for session caching and Bull for background job queues. These choices prevent rewrites later.
We also handle deployment and monitoring. Every Node.js app ships with a CI/CD pipeline on GitHub Actions, error tracking via Sentry, and uptime monitoring via Datadog. You get a running system, not a zip file.
How IRPR differs from other Node.js development agencies
Most agencies bill by the hour and change scope mid-project. We do not.
We write a detailed Roadmap in week 2 that defines every feature, every API endpoint, and every screen. You get a fixed price based on that Roadmap. No hourly billing, no surprise invoices.
Our engineers are senior only. We do not hire juniors or outsource to low-cost countries. Every developer on your project has at least 8 years of experience. You talk directly to the person writing the code.

- Sentry + Datadog monitoring included
Our Node.js app development process
We follow a four-phase process: Idea, Roadmap, Product, Release.
Phase 1 (Idea) takes 1 week. We review your concept, competitive landscape, and technical constraints. Phase 2 (Roadmap) takes 1 week. We produce a detailed specification with wireframes, API contracts, and a fixed price.
Phase 3 (Product) takes 8-12 weeks. We build the Node.js app in 2-week sprints with demos every Friday. Phase 4 (Release) takes 1 week. We deploy to production, set up monitoring, and hand over the code.
What ships with every Node.js project
You get a production-ready system, not a prototype.
Every Node.js app we build includes the infrastructure to run in production. We set up a CI/CD pipeline on GitHub Actions, error tracking with Sentry, and uptime monitoring with Datadog. Your team can deploy new code within 10 minutes.
We also include automated tests. Every project ships with at least 80% code coverage using Jest or Mocha. You get a Postman collection for API testing and a Swagger UI for documentation.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions
- Sentry error tracking
- Datadog uptime monitoring
- Jest unit tests (80%+ coverage)
- Postman API collection
- Swagger/OpenAPI documentation
- Docker Compose for local dev
- Deployment playbook (AWS or GCP)
- 1 hour of post-launch support per week

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. You know the cost before we write a line of code.
Senior engineers only
Every developer on your project has 8+ years of experience. We do not hire juniors or outsource. You talk directly to the person building your Node.js app.
8-12 week delivery
We ship production-ready Node.js apps in 8-12 weeks. Our average is 10.5 weeks across 200+ projects. You get a working app, not a prototype.
Full code ownership
You own the source code from day 1. We push code to your GitHub repository. No license fees, no vendor lock-in, no hidden restrictions.
Compliance built in
We build Node.js apps that meet HIPAA, PCI-DSS, and SOC 2 standards. We handle audit logging, encryption, and access controls natively.
Post-launch support included
Every project includes 1 hour of post-launch support per week for the first 3 months. We fix bugs, answer questions, and help your team take over.
