Leading Node.js API Development ConsultantsAPI Development
We build production-grade Node.js APIs for startups and enterprises. Ship your MVP in 8-12 weeks with a fixed price.
IRPR builds high-performance Node.js APIs using Express, Fastify, and NestJS. We integrate with PostgreSQL, MongoDB, and Redis, and deploy on AWS Lambda or ECS.
We ship production-ready APIs in 8-12 weeks with fixed pricing from $80K to $250K. Every API meets PCI-DSS, HIPAA, or SOC 2 compliance as needed.
Who hires us: CTOs scaling backend without hiring in-house, startup founders launching a SaaS MVP, enterprise architects modernizing legacy APIs, and product managers needing a reliable external team.
Types of software we ship.

Why leading Node.js API development consultants choose IRPR
We have shipped over 200 Node.js APIs for clients in 50+ countries.
Our team of senior engineers has delivered APIs for fintech, healthcare, ecommerce, and SaaS companies. Every project uses modern tooling like Docker, CI/CD, and automated testing.
We maintain a 98% on-time delivery rate across all projects. Our fixed-price model means no budget surprises, and we include 1 month of free post-launch support.
How we differ from generic dev shops
Most agencies bill hourly and deliver late. We don't.
Generic dev shops often start without clear scope, leading to cost overruns and missed deadlines. They rarely have compliance expertise or post-launch support built in.
IRPR gives you a fixed price after a 2-week Roadmap phase. We deliver in 8-12 weeks, include compliance (HIPAA, PCI, SOC 2), and hand over full code ownership.
- Unclear scope
- Hourly billing
- No compliance expertise
- Long timelines (6+ months)
- No post-launch support
- Code ownership unclear
- Fixed price from day one
- 8-12 week delivery
- HIPAA/PCI/SOC 2 ready
- Full code ownership
- CI/CD included
- Dedicated project manager
Our process for Node.js API development
From idea to production in 4 phases.
We start with a 2-week Roadmap to define scope, architecture, and fixed price. Then we build your API in 2-week sprints with weekly demos.
After development, we deploy to your cloud account and provide 1 month of free support. You own the code and documentation from day one.
What ships with every Node.js API project
You get more than just code.
Every API project includes production-ready infrastructure, documentation, and monitoring. We set up everything needed to run in production from day one.
- Source code in your Git repo
- CI/CD pipeline (GitHub Actions)
- API documentation (Swagger/OpenAPI)
- Unit and integration tests
- Docker containers
- Monitoring with Datadog
- Error tracking with Sentry
- Deployment scripts for AWS/GCP/Azure
- Postman collection
- 1-month post-launch support
