About
I’m Sefer Tasdemir. After a BUT in Computer Science (AGED track) at IUT d’Annecy and a year as an apprentice Data Analyst, I’m now doing a Master’s in Machine Learning for AI at Lyon 2.
I speak French and Turkish, and English at a professional level (TOEIC: 900 points). Away from code, I play chess and do sports.
