George Hadjidemetriou


I graduated from the University of Cyprus in 2019 with a bachelor's degree in Computer Science and I am currently studying for my master's degree in Interaction Technology at the University of Twente.

I consider myself a strong-willed individual with high motivation to complete any required task and provide, as an outcome, a product of the best possible quality. I am mostly interested into web development and game development, since I find myself spending a lot of time searching new technological trends in these areas and I am always eager to enhancing my skills with every opportunity.
