Premium Node.js API Development VendorAPI Development
We build production-grade Node.js APIs for SaaS, fintech, and healthcare. 200+ APIs shipped in 50+ countries.
IRPR builds premium Node.js APIs using Express.js, Fastify, and NestJS. We pair these with PostgreSQL, Redis, Kafka, and Docker for scalable, production-grade systems.
Every API ships in 8-12 weeks with fixed pricing between $80K and $250K. We deliver with full compliance: HIPAA for healthcare, PCI-DSS for fintech, and SOC 2 for SaaS.
Our clients are CTOs needing a scalable API backbone, startup founders building a SaaS MVP, enterprise architects migrating to microservices, and fintech companies requiring PCI-compliant payment APIs.

Why choose a premium Node.js API development vendor?
A premium vendor delivers APIs that scale, comply, and ship on time.
IRPR has built over 200 Node.js APIs for clients in 50+ countries. Our APIs handle 10,000+ requests per second and maintain 99.9% uptime. We use automated CI/CD pipelines with GitHub Actions and Docker.
Every API includes comprehensive test coverage (unit, integration, load) and security audits. We write OpenAPI specs before writing code, so your team can start integrating immediately.
Premium vs. generic: the real difference
Not all Node.js API vendors are equal. Here is what sets IRPR apart.
Generic dev shops bill hourly, skip compliance, and deliver undocumented code. IRPR gives you a fixed price, full documentation, and production-ready APIs that pass audits.
We assign senior engineers only (7+ years experience). Every API is built with monitoring (Datadog), error tracking (Sentry), and automated deployments from day one.
- Hourly billing with no cap
- No compliance experience
- Unclear delivery timelines
- Minimal test coverage
- No CI/CD pipeline
- You do not own the full codebase
- Fixed price from the start
- HIPAA, PCI-DSS, SOC 2 ready
- 8-12 week delivery with milestones
- 90%+ test coverage
- CI/CD with GitHub Actions and Docker
- Full code ownership, no lock-in
Our API development process in 4 phases
We follow a structured process to deliver your Node.js API on time and on budget.
Every project starts with a 2-week Discovery phase where we map your data model, endpoints, and compliance requirements. You get a detailed roadmap with fixed pricing.
Development runs in 2-week sprints with daily standups and a staging environment. We deploy to production only after load testing and security review.
What ships with every premium Node.js API
Every API delivery includes these production essentials.
You get more than code. Every project includes documentation, infrastructure-as-code, and monitoring so your team can operate independently from day one.
We also include a 30-day post-launch support period with a 4-hour SLA for critical issues. After that, we offer ongoing maintenance plans.
- Full source code in your private GitHub repo
- OpenAPI 3.0 (Swagger) documentation
- CI/CD pipeline using GitHub Actions
- Docker Compose and Dockerfile for local dev
- Datadog monitoring and alerting setup
- Sentry error tracking integration
- Security audit report (OWASP Top 10)
- Load test results (k6 or Artillery)
- Postman collection for all endpoints
- 30-day post-launch support with 4-hour SLA
What we ship in this practice.

Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. Our average project is $80K-$250K.
Senior engineers only
We hire senior Node.js engineers with 7+ years of experience. No juniors, no offshore teams. Every engineer has shipped at least 10 production APIs.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliant APIs from day one. Our infrastructure uses encrypted data at rest and in transit, audit logs, and access controls.
8-12 week delivery
Our process is designed for speed. We ship a production-ready API in 8-12 weeks. 98% of our projects finish on time or early.
Full code ownership
You own every line of code. No proprietary frameworks, no lock-in. We hand over the complete source code, documentation, and CI/CD pipeline.
Post-launch support included
Every project includes 30 days of post-launch support with a 4-hour SLA for critical issues. We also offer ongoing maintenance at $5K-$10K per month.
