Premium Node.js API Development DevelopersAPI Development
Hire senior Node.js engineers who build production-grade APIs in 8-12 weeks. Fixed pricing, full ownership, no surprises.
IRPR builds premium Node.js APIs using Express.js, Fastify, and Next.js for web apps, mobile backends, and microservices. Every API ships with OpenAPI docs, JWT authentication, and a CI/CD pipeline on GitHub Actions.
We deliver a fully production-ready API in 8-12 weeks with fixed pricing from $80K to $250K. All projects meet compliance standards: SOC 2 for SaaS, HIPAA for healthcare, PCI-DSS for fintech.
CTOs scaling B2B SaaS platforms hire us for load-tolerant REST APIs. Fintech founders need PCI-compliant payment APIs. Healthcare startups require HIPAA-safe patient data backends. Enterprise teams trust us to replace legacy Node.js code with maintainable microservices.
Types of software we ship.
REST API Development
Stateless RESTful endpoints with Express.js, rate limiting via Redis, and Swagger documentation. Ships in 8 weeks.
GraphQL API Development
Apollo Server with type-safe resolvers, batching, and real-time subscriptions. Integrates with PostgreSQL and MongoDB.
Microservices API
Decoupled services communicating via gRPC or RabbitMQ. Dockerized with Kubernetes orchestration for horizontal scaling.
Real-Time API (WebSocket)
Socket.io or WebSocket API for live chat, notifications, and streaming data. Handles 1M+ concurrent connections.
Third-Party Integration API
Stripe for payments, Twilio for SMS, SendGrid for email, and Salesforce CRM sync. Built with webhook handling.
Legacy Migration API
Reverse-engineer old monolithic APIs and rebuild them as clean Node.js services. Includes data migration scripts.
API Gateway Development
Central gateway using Kong or Nginx to route, rate-limit, and authenticate all internal services. Reduces latency by 40%.
Serverless API (AWS Lambda)
Event-driven APIs on Lambda with API Gateway for auto-scaling. Writes data to DynamoDB or Aurora Serverless.
We build for every business type.
SaaS platforms
Fintech companies
Healthcare organizations
Ecommerce brands
Logistics and travel
Why Premium Node.js API Development Matters
Your API is the backbone of your product. It must scale, stay secure, and ship fast.
We build Node.js APIs that handle 10K+ requests per second using Fastify and Redis caching. Every API has load testing via k6 and error tracking with Sentry. Our clients see 99.9% uptime from day one.
Security is baked in: JWT or OAuth2 authentication, input validation with Joi, and encrypted data at rest and in transit. We also include rate limiting, IP whitelisting, and SQL injection prevention.
Generic Node.js Shops vs. IRPR
Not all Node.js developers deliver premium APIs. The difference is in process, talent, and transparency.
Most shops bill by the hour, assign junior developers, and ship undocumented code. They often leave you with no CI/CD, no tests, and surprise maintenance costs after launch.
IRPR assigns senior engineers with 10+ years of experience. We write 100% test coverage, set up GitHub Actions pipelines, and hand over full code ownership. Our fixed-price model means no scope creep charges.
- Hourly billing, no fixed quote
- Junior devs with no code review
- No written unit or integration tests
- No CI/CD pipeline
- Code stays with the shop
- Bug fixes cost extra per hour
- Fixed price from Roadmap phase
- Senior engineers only, 10+ years experience
- 100% code coverage for critical paths
- CI/CD on GitHub Actions (automatic deploy)
- Full code ownership on day one
- 2-week post-release support included
Our 4-Phase API Development Process
We move from idea to production API in 8-12 weeks with no wasted cycles.
Phase 1 (Idea & Discovery, 2 weeks): We define your API endpoints, data models, threat model, and integration points. You get a detailed scope document and fixed price.
Phase 2 (Roadmap & Architecture, 2 weeks): We produce an architecture diagram, tech stack lock (Express vs. Fastify), database schema, and CI/CD setup. No surprises later.
What Ships with Every Premium Node.js API
You get production-ready code with full ownership. No black boxes.
Everything listed below is delivered in your private GitHub repository on day one of deployment.
- Source code in your GitHub or GitLab
- OpenAPI / Swagger documentation
- CI/CD pipeline (GitHub Actions)
- PostgreSQL or MongoDB database schema
- Authentication (JWT, OAuth2)
- Error tracking via Sentry
- Rate limiting and caching (Redis)
- Load testing report (k6)
- Deployment playbook (Docker, AWS)
- Two weeks of post-release support
What we ship in this practice.
Payment Processing API for Fintech
Built a PCI-compliant payment API handling 10M transactions monthly. Reduced checkout time by 40%. Stack: Node.js, Fastify, Stripe, PostgreSQL.
Patient Data API for Healthcare
Developed a HIPAA-compliant FHIR API that cut data retrieval from 5 seconds to 200ms. Stack: Express, GraphQL, PostgreSQL, AWS KMS.
Real-Time Chat API for SaaS
Designed a WebSocket API supporting 1 million concurrent users with under 100ms latency. Stack: Socket.io, Redis, Node.js.
Ecommerce Product Search API
Created a search API integrating with Shopify and Stripe. Reduced product sync time by 80% and improved search relevance by 35%. Stack: Elasticsearch, Fastify, Node.js.
Fleet Tracking API for Logistics
Built a real-time location API processing 50,000 data points per hour with 99.9% uptime. Stack: MQTT, Node.js, TimescaleDB, AWS IoT.
Social Media Aggregation API for Media
Developed an API aggregating data from 6 social platforms (Twitter, Instagram, LinkedIn, Facebook, YouTube, TikTok). Reduced manual reporting by 20 hours/week. Stack: Express, Node.js, Redis.
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. Over 200 projects delivered on budget.
Senior engineers only (10+ years)
We don't hire juniors. Every developer on your Node.js API has 10+ years of experience. Average tenure at IRPR is 5 years, so you get a stable team.
Full code ownership from day one
Code lives in your private repository from the first commit. No licenses, no vendor lock-in. You can deploy it yourself or any team can maintain it.
100% test coverage for critical paths
We write unit tests with Jest and integration tests with Supertest. Our CI pipeline fails if coverage drops below 80%. Bug rate at launch is under 0.5%.
98% on-time delivery rate
We track every project with weekly milestones. In the last 50 projects, only one missed the deadline (by 3 days due to client scope change).
Transparent weekly demos
Every Friday you see a live demo of working endpoints. No surprise reports, no waiting until the end. You can redirect or stop at any time.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
