Education

  • Master DNE
    Université Bordeaux Montaigne
    2021
    DNE - Dispositifs Numérique Educatifs Une formation professionalisante centrée sur la transmission des savoirs numériques et la création de séquences éducatives adaptées au numérique, avec un socle commun comprenant notamment de la gestion de projets numérique, des projets de création de sites internet, des notions de branding et de mise en page. La formation était centrée autour de projets concrets avec de réels clients, et encourageait la recherche d'information et l'apprentissage en auto-didacte, ce qui m'a permis de me tourner vers le design graphique. Depuis cette formation, je continue de me former et m'améliorer en autonomie.
