Karim Hcini
CEO, PomeLabs
" J'ai recruté et j'étais la manager de Noëlie pendant plusieurs années. Elle s'est bien intégrée à l'équipe et a rapidement pris des responsabilités au-delà de son périmètre de manière autonome. Elle était très efficace et fournissait des développements de qualité. Elle a su aussi d'immerger dans un code complexe et volumineux rapidement et faire des correctifs / ajouts de qualité. "
Marion Lok
Chef de projet, SEFI
" J'ai eu l'occasion de travailler avec Noëlie pendant deux ans chez SEFI, et j'ai pu apprécier sa fiabilité. Rigoureuse et méthodique, elle a su délivrer un code de qualité, fiable et maintenable. Elle se distingue également par un excellent relationnel, marqué par une attitude collaborative et un vrai sens du collectif, dans un esprit « low ego ». "
