Hire expert Node.js API consultants who ship in 8-12 weeks. Fixed pricing from $80K with full code ownership.
IRPR builds production-grade Node.js APIs using Express, NestJS, GraphQL, and REST. We use PostgreSQL, Redis, Docker, and GitHub Actions to deliver scalable, secure backends that handle millions of requests.
We have shipped 200+ products across 50+ countries. A typical Node.js API takes 8-12 weeks and costs $80K-$250K. All projects include compliance for HIPAA, PCI-DSS, or SOC 2 when required.
Our clients are CTOs needing scalable APIs for SaaS platforms, startup founders building MVPs for market validation, enterprise teams migrating legacy systems to microservices, and product managers requiring secure third-party integrations.
Types of software we ship.
REST API Development
Stateless RESTful APIs with Express, JWT authentication, and PostgreSQL. Ideal for CRUD-heavy mobile and web apps.
GraphQL API Development
Flexible GraphQL APIs using Apollo Server. Clients fetch exactly what they need, reducing payload size by 40% on average.
Microservices API Architecture

Why Professional Node.js API Development Consultants Matter
Our track record proves we deliver.
IRPR has shipped 200+ Node.js APIs for clients in 50+ countries. Every project includes senior engineers, fixed pricing, and a clear 8-12 week timeline.
We write testable, documented code with CI/CD pipelines from day one. You get a production-ready API with monitoring, error tracking, and full ownership.
Generic Dev Shop vs IRPR
The difference is measurable.
Most agencies bill hourly with vague scopes and junior developers. IRPR gives you a fixed price, senior engineers, and a clear contract.
We own the outcome, not the hours. Every project includes compliance, documentation, and 3 months free support.
- Hourly billing with no fixed scope
- Unclear code ownership
- No compliance expertise
- Junior developers learning on your dime
- No dedicated project manager
- No post-launch support
- Fixed price from $80K with scope locked in Roadmap phase
- Full code ownership in your repo
- HIPAA, PCI-DSS, SOC 2 compliant
- Senior engineers with 10+ years Node.js
- Dedicated PM with weekly demos
- 3 months free support after launch
Our 4-Phase Node.js API Development Process
From idea to production in 12 weeks.
We break every project into four phases: Idea, Roadmap, Product, Release. Each phase has a clear deliverable and a go/no-go decision.
You see working code every 2 weeks. No surprises at the end.
