Experienced Node.js API Development PartnerAPI Development
We build REST and GraphQL APIs in Node.js that scale to millions of users. 200+ products shipped, fixed pricing, 8-12 week delivery.
IRPR builds production-grade Node.js APIs for SaaS platforms, fintech apps, and ecommerce backends. We use Express, Fastify, NestJS, PostgreSQL, Redis, and deploy on AWS ECS or Lambda for serverless endpoints.
Every API project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle authentication (JWT, OAuth 2.0), rate limiting, logging (Sentry, Datadog), and database migrations. Compliance covered: HIPAA, PCI-DSS, SOC 2.
CTOs hire us when their in-house team lacks Node.js depth. Startup founders hire us to build a v1 API that investors can trust. Enterprise architects hire us to replace legacy SOAP APIs with modern REST or GraphQL endpoints.

Why You Need an Experienced Node.js API Development Partner
Building a production API is more than writing routes. It's about reliability, security, and performance from day one.
A poorly designed API costs you months of refactoring. IRPR's team has built over 200 APIs across 50 countries. We use Node.js 20 LTS, TypeScript, and automated testing (Jest, Supertest) to catch bugs before they hit production.
Every API ships with OpenAPI 3.0 documentation, Postman collections, and a CI/CD pipeline on GitHub Actions. You get full code ownership, zero vendor lock-in, and a team that answers Slack within 2 hours during business hours.
The Difference Between IRPR and a Generic Dev Shop
Most agencies build APIs that work today but break tomorrow. IRPR builds APIs that scale with your business.
Generic shops often skip testing, documentation, and monitoring. They hand over a codebase with no tests, no CI/CD, and no error tracking. You inherit a black box.
IRPR delivers a production-ready API with automated tests, CI/CD pipelines, Sentry error tracking, and Datadog performance monitoring. You get a system you can deploy and maintain yourself.
- No automated tests
- No API documentation
- No CI/CD pipeline
- No error monitoring
- No rate limiting
- No security audit
- 100% test coverage on critical paths
- OpenAPI 3.0 docs with Postman collection
- GitHub Actions CI/CD pipeline
- Sentry error tracking in production
- Rate limiting with Redis and IP blocking
- OWASP security audit before launch
Our Node.js API Development Process
From idea to production API in 8-12 weeks. Each phase has a clear deliverable.
Phase 1 (Week 1-2): Roadmap. We define endpoints, data models, authentication strategy, and integration points. You get a fixed price and timeline.
Phase 2 (Week 3-8): Build. We implement the API in weekly sprints with continuous deployment to a staging environment. You test each endpoint as it ships.
What Ships with Every Node.js API
Every deliverable includes these items. No hidden extras.
All code is yours from day one. We never use proprietary frameworks or libraries.
- Source code in your private GitHub repo
- OpenAPI 3.0 specification (YAML/JSON)
- Postman collection with example requests
- CI/CD pipeline on GitHub Actions
- Sentry error tracking configured
- Datadog or CloudWatch performance monitoring
- Rate limiting with Redis
- JWT or OAuth 2.0 authentication
- Database migration scripts (Knex or Prisma)
- Deployment runbook for AWS ECS or Lambda
