Professional Node.js API Development VendorAPI Development
We build production-grade Node.js APIs for B2B SaaS, fintech, and healthcare. 200+ products shipped, 50+ countries, fixed pricing from $80K.
IRPR builds professional Node.js API development services for companies that need scalable, secure backends. We use Node.js with Express or Fastify, TypeScript, PostgreSQL, Redis, and Docker.
Every project ships as a production-ready API with automated CI/CD, error tracking (Sentry), and monitoring (Datadog). Timeline is 12-14 weeks for a full MVP, with fixed pricing from $80K to $250K depending on complexity and compliance needs (HIPAA, PCI-DSS, SOC 2).
Who hires us: CTOs at Series A startups who need a v1 API in 12 weeks, engineering leads at enterprise who need a compliance-ready data layer, and product managers building multi-tenant SaaS platforms that must scale to 100K users.

Why Companies Choose IRPR for Node.js API Development
Our track record speaks for itself.
IRPR has shipped 200+ Node.js APIs for clients in fintech, healthcare, and SaaS. 98% of projects delivered on time and on budget.
We deploy production-grade APIs with Sentry error tracking, Datadog monitoring, and CI/CD pipelines. Average timeline is 12 weeks from kickoff to release.
How We Compare to Generic API Shops
Not all Node.js API vendors are the same. Here is the difference.
Most agencies charge by the hour and hand off code without monitoring or documentation. You get a zip file and a bill that grew 30%.
IRPR delivers a production-ready API with observability, compliance, and ongoing support. You own the code and get a fixed price from week 2.
- Hourly billing with no cap
- No compliance expertise (HIPAA/PCI)
- Hand-off after delivery, no support
- No monitoring or error tracking
- Single developer risk (bus factor)
- Scope creep is your problem
- Fixed price from week 2 (no hourly)
- HIPAA, PCI-DSS, SOC 2 built in
- Ongoing support and maintenance ($5K/mo)
- Full observability stack (Sentry, Datadog)
- Senior engineers only, 2-3 per project
- No surprises - roadmap phase defines everything
The IRPR Node.js API Development Process
We follow a proven four-phase process to ship your API on time and on budget.
Each phase has clear deliverables and a fixed price. The Roadmap phase (week 2) locks the final quote.
You receive weekly demos, a Slack channel with the team, and full visibility into progress via Linear.
What Ships with Every Node.js API from IRPR
Every project includes these deliverables by default. No extra fees.
You get a production-ready API with full documentation, CI/CD, monitoring, and deployment scripts. All code is yours.
We also include a deployment playbook so your team can take over or extend the API at any time.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Sentry error tracking and performance monitoring
- Datadog dashboards for API latency and errors
- PostgreSQL database with migrations
- Swagger/OpenAPI documentation
- Docker containerization with Docker Compose
- Deployment playbook for AWS or GCP
- Unit and integration tests (80%+ coverage)
- Rate limiting, authentication, and input validation

Why teams hire us.
Fixed Price, Not Hourly
We quote a fixed price after the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. 98% of projects ship on time and on budget.
Senior Engineers Only
Every project has 2-3 senior Node.js engineers (7+ years experience). No juniors, no contractors, no hand-offs. Your API is built by the same team from start to finish.
Compliance Built In
We handle HIPAA, PCI-DSS, SOC 2, and FERPA out of the box. Certified engineers configure encryption, audit logs, and access controls as part of every project.
Production-Ready From Day One
We ship with Sentry error tracking, Datadog monitoring, CI/CD pipelines, and automated testing. Your API is production-ready the day it deploys.
Full Code Ownership
You own 100% of the source code, documentation, and deployment playbooks. No licensing fees, no vendor lock-in, no restrictions.
Global, Async-First Collaboration
Our team spans 50+ countries with 4+ hour overlap with US time zones. We use Slack, Linear, and Notion for daily standups. You get a dedicated project manager and weekly demos.
