Introduction
J’ai plus de 14 ans d’expérience en IT et cybersécurité, avec un focus fort sur l’architecture réseau et sécurité. Aujourd’hui, je pilote des programmes à l’international (28 pays) en faisant le lien entre stratégie, architecture et opérations. Concrètement, je conçois des socles réseau et sécurité qui tiennent la route, puis je m’assure qu’ils vivent bien dans le run. J’aime quand c’est clair, déployable, et vraiment utilisable par les équipes, sans compliquer la vie de tout le monde.
