Senior Node.js API Development StudioAPI Development
We build production-grade Node.js APIs in 12 weeks. Fixed price, senior engineers only, zero surprises.
IRPR is a senior Node.js API development studio that builds RESTful and GraphQL APIs using Express, Fastify, and NestJS. We design APIs that handle millions of requests per day with sub-50ms response times.
Every project ships in 12-14 weeks with a fixed price between $80K and $250K. We handle compliance for HIPAA, PCI-DSS, and SOC 2 out of the box. You get a production-ready API with documentation, tests, and a CI/CD pipeline.
CTOs who need a reliable backend for a SaaS product. Product owners launching a mobile app that requires a scalable API. Healthcare companies that need a HIPAA-compliant data layer. Fintech startups that require PCI-DSS certified APIs.
Types of software we ship.
RESTful API
Standard JSON APIs built with Express or Fastify. Includes versioning, rate limiting, and Swagger documentation.
GraphQL API
Flexible GraphQL APIs using Apollo Server or Yoga. Supports real-time subscriptions and federated schemas.
Microservices API
Decoupled services connected via message brokers like RabbitMQ or NATS. Each service is independently deployable.
Webhook API
Event-driven APIs that push data to external systems using Stripe, Slack, or custom webhook endpoints.
Streaming API
Real-time data streams using Server-Sent Events or WebSockets. Built for live dashboards and notifications.
Third-party API Integration
Custom connectors to Shopify, Salesforce, HubSpot, or any REST/GraphQL API. Handles authentication and rate limits.
API Gateway
Centralized gateway using Kong or Express Gateway for authentication, throttling, and routing to multiple services.
Admin API
Internal APIs for managing users, roles, and system settings. Built with RBAC and audit logging.
We build for every business type.

Why a Senior Node.js API Development Studio Matters
Your API is the backbone of your product. A junior team will cost you time and money. We ship production-grade APIs in 12 weeks.
A poorly designed Node.js API breaks under load, leaks data, and costs thousands in rework. IRPR builds APIs that handle 10,000 requests per second with 99.9% uptime. We use Express, Fastify, and NestJS with PostgreSQL, Redis, and RabbitMQ.
We write comprehensive tests using Jest and Supertest. Every endpoint has a test suite that runs in CI. We also include Swagger documentation so your frontend team can start integrating on day one.
The Difference Between a Junior Freelancer and a Senior Studio
Hiring a single freelancer for your Node.js API is a gamble. IRPR gives you a team of senior engineers with a fixed price and a clear timeline.
Freelancers often disappear, underdeliver, or use inconsistent code standards. They skip tests, ignore security, and leave you with undocumented code. IRPR assigns a pod of 3-5 senior engineers who work synchronously across time zones.
We use code reviews, automated testing, and continuous integration. Every API we ship includes a Postman collection, a CI/CD pipeline on GitHub Actions, and a deployment guide. You get a production-ready API, not a prototype.

How We Build Your Node.js API in 12 Weeks
We follow a proven 4-phase process that eliminates guesswork. Every phase ends with a deliverable you can review and approve.
Phase 1 is the Roadmap. In week 2, we deliver a detailed technical specification, API contract, and a fixed price. You approve the plan before we write a single line of code.
Phase 2 is the Build. We work in 2-week sprints, deploying to a staging environment every sprint. You see progress in real time. Phase 3 is the Release, which includes load testing, security audit, and production deployment.
What Ships with Every Node.js API Project
Every API we build includes these deliverables by default. No hidden costs, no missing pieces.
We ship more than just code. Every project includes documentation, tests, a CI/CD pipeline, and a monitoring setup. Your team can start using the API immediately after deployment.
- Source code in your private GitHub repository
- Swagger/OpenAPI documentation
- Postman collection with example requests
- CI/CD pipeline on GitHub Actions
- Sentry error tracking
- Datadog monitoring dashboards
- Load testing report (k6 or Artillery)
- Security audit report (OWASP top 10)

Why teams hire us.
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. The price you see is the price you pay.
Senior engineers only
Every developer on your project has 8+ years of Node.js experience. We do not hire juniors or outsource to low-cost shops. You get a pod of 3-5 senior engineers who work full-time on your API.
12-week delivery guarantee
We ship production-ready APIs in 12 weeks, not 6 months. We have delivered 200+ projects on time with a 98% on-time record. If we are late, you do not pay for the extra weeks.
Built-in compliance
We build HIPAA, PCI-DSS, and SOC 2 compliant APIs out of the box. We handle data encryption, access controls, audit logs, and vulnerability scanning. You do not need a separate security audit.
Full code ownership
You own 100% of the source code, documentation, and infrastructure. There is no license fee, no vendor lock-in, and no recurring royalty. You can take the code to any team after the project ends.
30 days free support
After launch, we provide 30 days of free bug fixes and monitoring support. We help your team onboard and ensure the API runs smoothly. After that, you can extend support at a fixed monthly rate.
