Node.js API Development AgencyAPI Development
We build production-ready Node.js APIs in 8-12 weeks. Fixed price, senior engineers only.
IRPR builds production-grade Node.js APIs using Express, Fastify, NestJS, and microservices patterns with PostgreSQL, MongoDB, Redis, and AWS Lambda. Every API ships with CI/CD, Docker containers, and OpenAPI documentation.
We deliver a fully tested, documented, and deployed API in 8-12 weeks. Pricing is fixed from the Roadmap phase and ranges from $80K to $250K depending on complexity. Our APIs are built to HIPAA, PCI-DSS, and SOC 2 compliance standards when required.
CTOs scaling their product infrastructure hire us for custom backend development. Startup founders use us to build their MVP API in under 12 weeks. Enterprise product managers need us for secure third-party integrations. Engineering leaders outsource complex microservices to our senior team.
Types of software we ship.
RESTful API Development
Stateless APIs using Express or Fastify with PostgreSQL, Redis caching, and JWT authentication. Includes OpenAPI 3.0 spec generation.
GraphQL API Development

Why Node.js for API Development?
Node.js powers over 80% of modern APIs with its event-driven, non-blocking architecture.
Node.js handles 10,000+ concurrent requests with ease, making it the top choice for real-time and high-traffic APIs. Its massive npm ecosystem (1.5 million+ packages) means we never reinvent the wheel.
IRPR has shipped 200+ Node.js APIs across 50 countries. We use proven patterns like dependency injection, error handling middleware, and request validation to ensure your API is secure, scalable, and maintainable.
Generic Dev Shop vs IRPR
Not all Node.js API development agencies deliver the same quality.
Many shops bill by the hour, assign junior developers, and hand you code with no documentation. You end up with a fragile API that breaks in production and no one to fix it.
IRPR works differently. Every project gets a fixed price, senior engineers with 10+ years of experience, and a complete production-ready API with documentation, monitoring, and CI/CD built in.
- Hourly billing with no cap
- No dedicated project manager
- Junior developers learning on your dime
- No CI/CD pipeline
- No API documentation included
- Code ownership unclear
- Fixed price from day one
- Senior engineers with 10+ years
- CI/CD with GitHub Actions and Docker
- OpenAPI/Swagger docs included
- Full code ownership
- 12-week delivery guarantee
How We Build Your Node.js API
A transparent process from idea to deployment, with clear milestones and deliverables.
We start with a two-week Roadmap phase where we define endpoints, data models, authentication, and third-party integrations. You get a fixed price and timeline before any code is written.
Then we build, test, and deploy in 6-10 weeks using feature branches, code reviews, and automated testing. Every API ships with a monitoring dashboard and a one-month post-launch support period.
What Ships With Every API
Everything you need to run in production, from day one.
Our Node.js API development agency delivers more than just code. Each project includes a complete operational toolkit so your team can deploy, monitor, and extend the API immediately.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions with auto-deploy
- Dockerized deployment scripts for any cloud
- OpenAPI 3.0 documentation with Swagger UI
- Postman collection with example requests
- Sentry error tracking and performance monitoring
- Datadog dashboard for API metrics and alerts
- Load testing report with k6 results
- Security audit report (OWASP top 10)
- 1 month post-launch support with on-call engineer

Fixed Price, Not Hourly
Every Node.js API project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges.
Senior Engineers Only
Our team averages 10+ years of Node.js experience. No junior developers, no outsourcing, no code quality issues.
Full Code Ownership
You own every line of code from day one. We never use proprietary frameworks or lock you into our infrastructure.
CI/CD from Day One
Every project starts with a GitHub Actions pipeline, Docker containers, and automated tests. Your API is deployable within the first week.
Post-Launch Support Included
All projects include 1 month of post-launch support with a dedicated engineer. We fix bugs, answer questions, and help your team take over.
Compliance Ready (HIPAA, PCI-DSS, SOC 2)
