About this gig

Need a backend that actually works in production not just on localhost?

I build clean, well-structured backend systems using Node.js/NestJS and Java Spring Boot, with real databases, proper authentication, and code you can actually maintain and scale.

What I can build for you:

  • REST APIs for web and mobile apps
  • Authentication systems (JWT, OAuth 2.0, role-based access)
  • Database design and integration (PostgreSQL, MongoDB)
  • E-commerce backends (products, orders, payments)
  • Booking and reservation systems
  • Admin dashboards and management APIs
  • Dockerized, deployment-ready applications

Tech I work with:

  • Runtime/Framework: Node.js, NestJS, Express, Java Spring Boot
  • Databases: PostgreSQL, MongoDB, Redis
  • Auth: JWT, OAuth 2.0, RBAC
  • DevOps: Docker, GitHub Actions, AWS deployment
  • API Design: REST, clean architecture, proper error handling

Recent projects I've built:

  • Microservices-based Delivery Management Platform (Spring Boot + Kafka + Kubernetes)
  • Full E-Commerce backend with inventory, orders, and payment workflows
  • Medical Clinic Reservation System with booking logic and user management
