Orfeas Liossatos

I study Data Science and Mathematics at EPFL in Switzerland, and I'm currently an intern at Ubisoft.

I want to make video games, become a swordsman, play in a band, and understand the universe and myself.

Resume

Education

• Masters degree in Data Science, EPFL [2022-now]
  • Minor in Mathematics, EPFL
• Bachelors degree in Computer Science, EPFL [2019-2022]

I completed a full-year exchange program at the University of Edinburgh in the third year of my bachelor's degree.

Languages

I speak English and French fluently. I speak German, Greek, and Japanese at an intermediate level. I'm currently learning Mandarin.
