Top Node.js API Development FirmAPI Development
Build secure, scalable APIs with Node.js. Our senior engineers deliver production-ready REST and GraphQL APIs in 8-12 weeks.
IRPR builds custom APIs with Node.js, Express, and TypeScript. We design RESTful and GraphQL endpoints that handle thousands of requests per second with sub-50ms latency.
Every API ships with a CI/CD pipeline, automated testing, and API documentation. Timelines range from 8-12 weeks for a complete MVP. Pricing is fixed: $80K-$250K. We comply with HIPAA, PCI-DSS, and SOC 2.
We work with CTOs scaling their product, startup founders needing a production-ready API, and SaaS companies migrating to microservices. Each client gets a dedicated senior Node.js engineer.

Why Choose a Top Node.js API Development Firm
IRPR delivers production-ready Node.js APIs with measurable results.
Our teams have shipped over 200 products across 50 countries, with 98% on-time delivery. Every API passes security audits for HIPAA, PCI-DSS, and SOC 2.
We use automated testing covering 90%+ code coverage and integrate Sentry for real-time error tracking. Average response times under 50ms.
How IRPR Compares to Generic Dev Shops
Not all API development firms deliver the same quality. Here is the difference.
Generic agencies often use hourly billing and lack dedicated senior engineers. They may use outdated patterns and skip documentation.
IRPR assigns a senior Node.js engineer to every project, uses fixed pricing from the Roadmap phase, and delivers comprehensive API documentation and monitoring.
- Hourly billing that inflates costs
- Junior developers with no Node.js expertise
- No automated testing
- API docs are an afterthought
- No CI/CD pipeline
- No post-launch monitoring
- Fixed-price quotes from week 2
- Senior Node.js engineers only (8+ years)
- Automated tests with 90%+ coverage
- OpenAPI/Swagger docs by default
- GitHub Actions CI/CD
- Sentry and Datadog monitoring
Our Node.js API Development Process
We follow a proven 4-phase framework: Idea, Roadmap, Product, Release.
In the Idea phase, we clarify requirements and define endpoints. Roadmap week 2 delivers a fixed quote and architecture plan.
Product phase is iterative, with bi-weekly demos. Release includes deployment, monitoring, and documentation.
