Why Choose IRPR for Node.js API Development
We have shipped over 200 products using Node.js, with a 98% on-time record.
Our API projects average 12 weeks from kickoff to production. We use TypeScript, Prisma, and PostgreSQL for type safety and performance. Each API is load-tested for 10K requests per second before deployment.
We assign senior Node.js engineers only. Everyone has 10+ years of backend experience. You get a fixed price after the 2-week Roadmap phase. No hourly billing, no scope creep.
How IRPR Compares to Generic Dev Shops
Generic agencies overpromise and underdeliver. IRPR gives you a fixed roadmap and real code.
Most agencies bill by the hour and change requirements every sprint. IRPR uses a fixed-price model defined during the Roadmap phase. You know the cost before any code is written.
Our team writes unit tests, integration tests, and API contract tests by default. We deploy via GitHub Actions to AWS with staging and production environments. You get full access to all repositories from day one.
- Hourly billing with no cap
- Scope creep every sprint
- Untested code in production
- You don't own the IP
- Slow email-only communication
- No DevOps or monitoring
- Fixed price after Roadmap
- Clear scope in week 2
- Full test coverage
- You own all code and IP
- Daily Slack updates
- CI/CD and Sentry included
Our Node.js API Development Process
From idea to deployment in 12 weeks.
We follow a 4-phase process. Phase 1 is the Roadmap: we define architecture, endpoints, data models, and compliance needs. This takes 2 weeks and costs a fixed $5K, which is deducted from the total project price.
Phase 2 is the Build: 6 weeks of development with 2-week sprints. Phase 3 is Testing: load testing with k6, security audit with OWASP ZAP, and documentation. Phase 4 is Deployment to production with CI/CD and monitoring.
