About this gig

Are you looking for a reliable back-end developer to build, fix or improve your system?


I can help you create REST APIs, authentication systems, database integrations, backend features and scalable services using Java, TypeScript, Node.js, Redis, PostgreSQL, MySQL or MongoDB.


I have experience working with real-world backend systems, including infrastructure for high-traffic Minecraft networks with hundreds of simultaneous users.


What I can do for you:

  • REST API development
  • Backend feature implementation
  • Bug fixing
  • Database modeling
  • JWT authentication
  • Redis integration
  • Docker setup
  • API documentation with Swagger/OpenAPI
  • Clean code and maintainable structure


Please contact me before placing an order so we can discuss your requirements.
