Why IRPR is the top Node.js API development vendor
We deliver production-grade Node.js APIs that handle millions of requests per day.
IRPR has shipped 200+ Node.js projects across 50 countries. Our APIs handle an average of 500,000 requests per day with 99.9% uptime. Every endpoint is load tested with k6 before launch.
Our fixed pricing model (USD 80K to 250K) covers everything from architecture to deployment. You get a serverless or containerized API running on AWS Lambda or ECS, complete with CloudWatch monitoring and Datadog dashboards.
How we differ from generic Node.js development shops
Most agencies deliver one thing: a working API. IRPR delivers a scalable, documented, and monitored system you can hand off to any engineering team.
Generic dev shops often skip load testing, omit API documentation, and hand you a codebase with no CI/CD. Their hourly billing model encourages slow progress and scope creep.
IRPR works differently. We build APIs with OpenAPI specs, automated test coverage above 80%, and deploy via GitHub Actions to staging and production environments. Every project includes a post-launch documentation runbook.
- Hourly billing - unexpected invoices
- No load testing under realistic traffic
- No API documentation generated
- No CI/CD pipeline included
- No monitoring or alerting set up
- No compliance or security audit
- Fixed price - no surprises
- k6 load testing with 5000+ virtual users
- OpenAPI 3.0 docs autogenerated
- GitHub Actions CI/CD pipeline
- Datadog monitoring with PagerDuty alerts
- HIPAA/PCI/SOC 2 compliance checked
Our Node.js API development process in 4 phases
From discovery to deployment, we follow a structured process that ensures your API ships on time and on budget.
Every engagement starts with a 1-week discovery phase. We map your data models, define endpoints, and agree on performance benchmarks. By day 5 you have a written specification.
Development runs in 2-week sprints with demo reviews every Friday. We use TypeScript, Prisma, and Zod for type safety. The final phase includes documentation, load testing, and deployment to your cloud account.
What ships with every Node.js API project
You don't just get code. You get a complete system that your team can own and extend immediately.
Every API project from IRPR includes the source code, CI/CD pipeline, monitoring, and documentation. We never hold your code hostage. The entire repository lives in your GitHub or GitLab account from day one.
Post-launch, you receive a runbook with architecture diagrams, deployment instructions, and troubleshooting guides. Our team stays on call for 30 days to handle any issues.
- Full source code in your GitHub/GitLab repo
- CI/CD pipeline with GitHub Actions
- Docker image for local development
- OpenAPI 3.0 documentation (Swagger UI)
- k6 load test scripts with 5000+ VUs
- Datadog monitoring dashboards
- Sentry error tracking integrated
- Rate limiting and API key authentication
- Database migration scripts (Prisma)
- 30-day post-launch support and runbook
What we ship in this practice.
Real-time auction API for a travel platform

Why teams hire us.
Fixed price, not hourly
Every API project gets a fixed quote after the 1-week Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges. The price shown is the price paid.
Senior Node.js engineers only
IRPR only hires developers with 8+ years of Node.js experience. Each engineer has shipped at least 5 production APIs using TypeScript, Express, and PostgreSQL.
Full code ownership from day one
All code lives in your GitHub repository from the first commit. We never hold your IP. You can terminate the engagement at any time with zero loss.
12-week MVP guarantee
We guarantee a production-ready MVP within 12 weeks. Every project includes load testing, documentation, and CI/CD. Over 98% of our projects launch on time.
Compliance ready (HIPAA, PCI, SOC 2)
We build APIs that pass health, payment, and security audits. Our templates include encryption, audit logging, and access controls for HIPAA, PCI-DSS, and SOC 2.
Weekly demos and transparency
You see a working demo every Friday. Our project dashboard tracks sprint progress, open issues, and deployment status. No black box development.
Idea → Roadmap → Product → Release.
