Expert Node.js API Development DevelopersAPI Development
We build production-ready Node.js APIs in 8-12 weeks. Fixed price, senior engineers, full ownership.
IRPR builds expert Node.js API development for startups and mid-market companies. We use Node.js, Express.js, PostgreSQL, Redis, and AWS Lambda to create fast, secure, and scalable APIs. Our senior engineers handle everything from RESTful endpoints to GraphQL, WebSockets, and third-party integrations.
We ship your API in 8-12 weeks with fixed pricing from $80K to $250K. Every project includes full code ownership, CI/CD pipelines, Sentry error tracking, and 99.9% uptime SLAs. We have delivered APIs for HIPAA-compliant healthcare systems, PCI-DSS compliant fintech platforms, and SOC 2 compliant SaaS products.
Founders with a validated idea hire us to build their first API. CTOs who need to scale a legacy system hire us to modernize their backend. Product managers at funded startups hire us to ship a new integration layer in weeks, not months.

Why expert Node.js API development developers matter
A poorly built API costs you time, money, and users.
IRPR has shipped 200+ Node.js APIs for clients in 50 countries. Our senior engineers write clean, tested, and documented code that handles 10,000+ requests per second. We use Express.js, Fastify, or Koa based on your traffic patterns.
Every API we build includes automated tests with Jest, API documentation with Swagger, and monitoring with Datadog. We deploy on AWS using ECS or Lambda, with auto-scaling and 99.9% uptime. No spaghetti code, no hidden tech debt.
Generic dev shop vs IRPR
Most agencies overpromise and underdeliver on API projects.
We have fixed this problem for 200+ clients. Our process is transparent, our pricing is fixed, and our engineers are senior only. No junior developers, no offshore teams, no hidden fees.
You get a dedicated team lead who writes code every day. You get a Slack channel, weekly demos, and full access to the repo from day one. We ship on time or we tell you early.
- Hourly billing with no cap
- Junior developers learning on your project
- No documentation or tests
- Offshore team with timezone lag
- No monitoring or error tracking
- You own nothing after payment
- Fixed price from $80K to $250K
- Senior engineers with 10+ years experience
- Swagger docs and 90%+ test coverage
- US-based team with 4-hour overlap
- Sentry, Datadog, and PagerDuty monitoring
- Full code ownership from day one
Our Node.js API development process
We follow a 4-phase process that de-risks your project.
Phase 1: Idea validation and technical feasibility in 1 week. We map your requirements, choose the right stack, and give you a fixed price. Phase 2: Roadmap with wireframes and database schema in week 2.
Phase 3: Build your API in 8-12 weeks with weekly demos. Phase 4: Deploy to production with CI/CD, monitoring, and documentation. We support you for 30 days post-launch.
What ships with your Node.js API
You get more than code. You get a production-ready system.
Every API project includes infrastructure, monitoring, and documentation. You can deploy to production on day one without hiring another engineer. We set up everything you need to run at scale.
Our standard stack includes Node.js, PostgreSQL, Redis, AWS ECS or Lambda, and GitHub Actions. We add Sentry for error tracking, Datadog for performance monitoring, and PagerDuty for alerts.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Automated tests with Jest (90%+ coverage)
- API documentation with Swagger/OpenAPI
- Sentry error tracking
- Datadog performance monitoring
- AWS infrastructure as code (Terraform)
- PostgreSQL database with migrations
- Redis cache for high performance
- Post-launch support for 30 days
What we ship in this practice.
Real-time chat API for a telehealth app

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. You know the exact cost before we build.
Senior engineers only
Our team averages 12 years of experience. No junior developers learning on your project. Every engineer has shipped at least 5 production APIs.
Full code ownership
You own everything from day one. Source code, documentation, infrastructure scripts, and IP. No licensing fees, no vendor lock-in.
8-12 week delivery
We ship your MVP in 8-12 weeks. Our process is optimized for speed without sacrificing quality. 98% of our projects ship on time.
Production-ready from day one
Every API includes CI/CD, monitoring, error tracking, and auto-scaling. You can deploy to production immediately without hiring another engineer.
Compliance built in
We build HIPAA, PCI-DSS, SOC 2, and GDPR compliant APIs. Our engineers know the regulations and bake compliance into the architecture from the start.
