Node.js Development
I build backend systems with Node.js that are reliable, fast, and easy to maintain. From REST APIs to event-driven microservices, I design server-side architectures that scale with your business. Every project uses TypeScript by default for type safety and long-term code health.
key benefits
- — RESTful and GraphQL API development with Express or Fastify, structured for clarity and performance
- — Type-safe backend code with TypeScript and MikroORM for predictable PostgreSQL interactions
- — Microservice architectures with clear domain boundaries, message queues, and independent deployability
- — Real-time features using WebSockets and Server-Sent Events for live updates and collaboration
- — Comprehensive error handling, logging, and monitoring so issues surface before users notice them
what i build with node.js
REST and GraphQL APIs
Well-documented, versioned APIs with auth, rate limiting, and validation baked in from day one.
Microservices
Independently deployable services communicating via message queues or HTTP, designed for team scale.
Real-Time Applications
Chat systems, live dashboards, notification services, and collaborative tools powered by WebSockets.
Background Job Processors
Reliable task queues for email delivery, data processing, report generation, and scheduled workflows.
