Projects

Justas's portfolio
This is the website you are currently on! I created this portfolio to have a central space where I can put my projects in and demonstrate some of them.

Nordic + Baltic BTE
As a co-owner of the Nordic + Baltic BTE digital video game project, I serve as the technical lead, focusing primarily on server management.

Build The Earth
As a support team member for the Build The Earth digital game project, I assist users with their requests and issues.

A highly experimental chess bot I'm creating for educational purposes. It is not designed to be used in chess game analysis or to compete with others.
