Senior Node.js Development FirmDevelopment Firm
Hire a senior Node.js development firm with a fixed price and a proven process. We build production-grade Node.js applications in 8-12 weeks.
IRPR builds production-grade Node.js applications for startups and enterprises. We use Node.js with TypeScript, Express, NestJS, and PostgreSQL to deliver scalable APIs and microservices.
Every project ships as a complete product in 8-12 weeks. Our fixed pricing starts at $80K and goes to $250K depending on complexity. We handle HIPAA, PCI DSS, and SOC 2 compliance.
CTOs at funded startups hire us to build their MVP without technical debt. Product managers at mid-size companies hire us to rebuild legacy Node.js apps. Enterprise architects hire us to build scalable microservices architectures. Non-technical founders hire us because we guide them from idea to launch.

Why choose a senior Node.js development firm
Experience and process matter more than code.
A senior Node.js development firm like IRPR brings deep production experience. We have shipped over 200 Node.js applications across fintech, healthcare, and SaaS.
Our engineers average 10 years of Node.js experience. We have written code for systems handling 10 million monthly API calls and $50 million in transactions.
Generic firm vs IRPR: the real difference
Most Node.js development shops work differently than we do.
Generic dev shops often hire juniors, bill hourly, and skip compliance. They deliver code that works today but breaks tomorrow.
IRPR is built for serious product teams. We fix the price upfront, assign senior engineers, and ship production-ready software with full documentation.
- No project manager or transparent reporting
- Hourly billing with no cap
- No compliance expertise (HIPAA, PCI)
- No post-launch support or warranty
- Code quality varies by developer
- No roadmap phase; starts coding immediately
- Fixed price after 2-week Roadmap phase
- Dedicated senior engineers (10+ years avg.)
- HIPAA, PCI DSS, SOC 2 compliance built in
- 12-week delivery guarantee with 1-year warranty
- Full code ownership in your private repo
- CI/CD, monitoring, and automated tests included
Our process for building Node.js applications
We follow a 4-phase process that removes surprises.
Every project starts with a Roadmap phase where we define scope, architecture, and a fixed price. No coding happens until you approve the plan.
After Roadmap, we design the system, build iteratively, and deploy with full CI/CD. You see live demos every week.
What ships with every Node.js project
You get more than just code. Every delivery includes the full operational stack.
We believe in shipping production-ready software, not just loose code files. Our checklist covers everything from source control to monitoring.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Docker containerization for local and production
- Sentry error tracking with alerts
- Automated tests (unit + integration, 80% coverage)
- PostgreSQL schema with migrations
- API documentation (Swagger / OpenAPI)
- Deployment scripts for AWS ECS or Lambda
- Logging to CloudWatch or Datadog
- One-year bug fix warranty with 24-hour SLA

Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote after the Roadmap phase (week 2). Our clients never get surprise invoices because we do not bill by the hour.
Senior engineers only
IRPR's team averages 10+ years in production Node.js. We do not staff juniors or offshore teams with minimal oversight.
Compliance expertise
We have built HIPAA-compliant telehealth backends and PCI DSS-compliant payment systems. Our architecture reviews catch compliance gaps before the first line of code.
12-week delivery guarantee
We deliver production-ready MVPs in 12 weeks or your next sprint is free. This is backed by a process refined over 200+ projects.
Full code ownership
When the project ends, you own every file. We never hold code hostage or require ongoing licensing fees.
Transparent communication
We use linear.app for daily updates and weekly demos. Clients see live progress on their Jira or Trello if they prefer.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
Questions clients ask first.
