Why Hire Top Node.js API Development Developers
Our team has built over 200 APIs for startups and enterprises across 50 countries.
Every API we ship is designed for scalability and security. We use Node.js with Express or Fastify, PostgreSQL or MongoDB, and deploy on AWS or GCP with Docker containers.
We deliver in 8-12 weeks with a fixed price. You get full ownership of the code, automated CI/CD pipelines, and compliance with HIPAA, PCI-DSS, or SOC 2.
IRPR vs Generic Development Shops
Most agencies promise quality but deliver junior developers and vague timelines.
We see clients who lost months with hourly-billed teams that delivered incomplete APIs. They came to IRPR for a fixed price, senior engineers, and a clear 8-12 week roadmap.
Our process starts with a 2-week Roadmap phase where we define the API contract, data model, and deployment plan. No surprises, no scope creep.
- Vague timelines and hourly billing
- Junior developers learning on your project
- No compliance expertise (HIPAA, PCI, SOC 2)
- No code ownership guarantee
- No CI/CD or monitoring by default
- Slow response after launch
- Fixed price from $80K, no surprises
- Senior engineers with 8+ years Node.js experience
- Built-in HIPAA, PCI-DSS, SOC 2 compliance
- Full source code ownership from day one
- CI/CD with GitHub Actions, Sentry, and Docker
- 2-week kickoff and ongoing support
Our Node.js API Development Process
We follow a four-phase process that guarantees on-time delivery.
Every project starts with a Roadmap phase where we write user stories, define the API schema, and set up the cloud infrastructure. You get a fixed price and timeline before any code is written.
During development we work in 2-week sprints with daily standups and a shared Jira board. You see working endpoints every sprint and can adjust priorities.
What Ships With Every Node.js API Project
You get a production-ready API with everything needed to scale.
Every deliverable includes the source code, infrastructure as code, and monitoring tools. No hidden dependencies or vendor lock-in.
- Source code in your private GitHub repository
- CI/CD pipeline with GitHub Actions and Docker
- API documentation via Swagger or Postman
- Sentry error tracking and performance monitoring
- Unit and integration tests with 80%+ coverage
- Database migrations and seed scripts
- Deployment scripts for AWS or GCP
- Security audit report covering OWASP top 10
- Post-launch support for 30 days

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 total cost before we write a single line of code.
Senior Engineers Only
Our team averages 8+ years of Node.js experience. Every developer has built production APIs handling millions of requests. No junior developers learning on your project.
8-12 Week Delivery
We ship a production-ready API in 8-12 weeks. Our process is optimized for speed: parallel sprints, reusable components, and automated testing. 98% of our projects deliver on time.
Full Code Ownership
You own every line of code from day one. We deliver the source code in your repository with no proprietary libraries or hidden dependencies. You can run the API anywhere.
Compliance Built In
We build HIPAA, PCI-DSS, and SOC 2 compliant APIs by default. Our infrastructure includes encryption, audit logs, and access controls. We have passed over 50 compliance audits.
Post-Launch Support
We provide 30 days of post-launch support for every project. We monitor the API, fix bugs, and help your team take over. After that, we offer ongoing maintenance at a fixed monthly rate.
