Node.js API Development DevelopersAPI Developers
We build production-ready Node.js APIs in 8-12 weeks. Fixed pricing, senior engineers, full ownership.
IRPR builds Node.js APIs using Express, Fastify, and NestJS with PostgreSQL, Redis, and Docker. Our senior engineers design RESTful and GraphQL endpoints that handle thousands of requests per second.
Every API ships in 8-12 weeks with a fixed price between $80K and $250K. We support compliance standards like HIPAA, PCI-DSS, and SOC 2 out of the box.
We work with CTOs scaling their product, startup founders launching an MVP, enterprise teams migrating legacy APIs, and product managers adding new features to existing platforms.
Types of software we ship.
REST API
Stateless, cacheable endpoints using Express or Fastify with OpenAPI documentation and JWT auth.
GraphQL API
Flexible data queries with Apollo Server, TypeGraphQL, and Prisma for type-safe resolvers.
Microservices API
Decoupled services communicating via RabbitMQ or NATS, deployed on Kubernetes with Docker.
Real-time API (WebSocket)
Low-latency bidirectional communication using Socket.io or WS, with Redis pub/sub for scaling.
Third-party API Integration
Connect Stripe, Salesforce, HubSpot, or custom endpoints with retry logic and rate limiting.
Internal API / Backend for SaaS
Private APIs for your SaaS platform with role-based access, audit logs, and database migrations.
API Gateway / Proxy

Serverless API (AWS Lambda)
Event-driven functions with API Gateway, DynamoDB, and CloudFormation for auto-scaling.
We build for every business type.
SaaS companies
Mobile apps
Ecommerce
Fintech

Why choose IRPR for Node.js API development
We deliver production-grade APIs on time and on budget.
Every API we build is designed for scale from day one. Our senior engineers use Node.js 20, TypeScript, and automated testing to ensure 99.9% uptime and zero-downtime deployments.
We have shipped APIs for 200+ products across 50 countries. Our average delivery time is 12 weeks, and 98% of projects finish on schedule.
How IRPR differs from other Node.js API shops
Most agencies bill hourly and hand off messy code. We do the opposite.
Generic dev shops often use junior developers, change scope mid-project, and deliver undocumented APIs. You end up with technical debt and surprise invoices.
IRPR assigns senior engineers only, locks the scope in a Roadmap phase, and delivers clean, documented code with full ownership from day one.
- Junior developers learning on your project
- Hourly billing with no cap
- Scope creep without change orders
- No automated tests or CI/CD
- Code ownership unclear
- Average delivery 6+ months
- Senior engineers with 10+ years experience
- Fixed price from the Roadmap phase
- Scope locked in week 2
- Automated tests, CI/CD, and monitoring
- Full code ownership from day one
- 8-12 week delivery
Our 4-phase process for Node.js API development
From idea to production in 8-12 weeks.
We follow a structured process that removes guesswork. Each phase has a clear deliverable and a fixed price.
You see working software after the Roadmap phase and can give feedback every week.
What ships with every Node.js API project
You get everything needed to run in production from day one.
We don't just send code. Each delivery includes infrastructure, documentation, and monitoring so your team can take over immediately.
All projects include a 30-day warranty period where we fix any bugs at no extra cost.
- Source code in your GitHub/GitLab repo
- CI/CD pipeline on GitHub Actions or GitLab CI
- Docker Compose and Kubernetes manifests
- API documentation with Swagger/OpenAPI
- Automated unit and integration tests (Jest, Supertest)
- Sentry error tracking and Datadog monitoring
- Database migrations (Prisma or Knex)
- Postman collection for testing
- Deployment guide and runbook
- 30-day post-release support
What we ship in this practice.
Real-time chat API
Built a WebSocket-based chat API using Socket.io and Redis for a social app. Handles 50,000 concurrent connections with 200ms latency. Reduced server costs by 40%.
Payment processing API
Developed a PCI-compliant payment gateway API with Stripe integration and idempotency keys. Processes 10,000 transactions per hour with 99.99% uptime.
Inventory management API
Created a RESTful API for a nationwide ecommerce chain using Express and PostgreSQL. Syncs inventory across 200 warehouses in under 2 seconds.
Telehealth appointment API
Built a HIPAA-compliant API with NestJS and AWS HealthLake. Handles scheduling, video calls, and EHR integration. Reduced no-show rate by 25%.
SaaS analytics API
Designed a GraphQL API for a B2B analytics platform using Apollo Server and ClickHouse. Queries return aggregated data in under 100ms for 1M+ records.
MLS data API for real estate
Developed a REST API that aggregates MLS listings from 50+ sources using Node.js and Elasticsearch. Provides full-text search with geolocation filters.
Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges.
Senior engineers only
We don't use juniors. Every engineer has 10+ years of experience and has shipped at least 5 production Node.js APIs.
Compliance built in
We handle HIPAA, PCI-DSS, and SOC 2 requirements from day one. Your API is audit-ready from the first deployment.
Async-first, global team
Our team works across 50+ countries with 4+ hours of overlap with US time zones. You get daily updates without waiting for meetings.
Full code ownership
You own every line of code from day one. No licensing fees, no lock-in, no restrictions on reuse.
12-week delivery guarantee
We ship most APIs in 8-12 weeks. If we miss the deadline, you get 10% off the final payment.
