Profile bio

About Grégoire Cousin

Actuellement employé en tant que “FullStack Web Engineer”, j’ai d’abord obtenu en 2012 un “bachelor en ingénieur du son”. J’ai ensuite travaillé pour plusieurs studios d’enregistrement internationalement reconnus. Cependant, désireux de compléter mes connaissances, je me suis tout naturellement tourné vers l’informatique, et dans la foulée, ai obtenu en 2019, un Master en “computer sciences”, ce qui équivaut à un bac +5. Ma passion pour la technologie ne pouvait pas être complète, sans un long passage chez Apple, aux États-Unis, puis en France. J’ai eu l’occasion de me diversifier. Par exemple, j'ai intégré l'équipe qui a mis en place la partie client pour l'Ademe, un programme de service d'appui à la transition énergétique. J'ai ensuite travaillé pour la SNCF en tant que FullStack Developer, sur une application pour les transports en commun où j'ai participé à la construction de son architecture et les flux transverses exploités à travers leurs services. Suite à mon experience chez la SNCF j'ai intégré l'Oreal où j'ai travailler sur des fonctionnalités de leurs nouvelles architectures, ainsi qu'intégrer l'équipe transverse dont le but était d'harmoniser les differents services dans leurs eco-system.Enfin, j'ai abordé un projet de sécurité chez la SNCF Connect dont le but de la mission est de récupérer les flux des applicatifs interne, traiter les failles de sécurité et de mettre à disposition les résultats de ces analyses sur une plateforme développée en React / AWSCette diversité de conception dans la programmation, ne connaît pas de limites, donnant à mon sens à la technologie, le pouvoir de stimuler le progrès à un rythme exponentiellement rapide et efficace, jamais égalé. C’est cela, qui correspond parfaitement à ma nature curieuse et passionnée. Parallèlement à mon travail, je mène mes propres projets personnels: certains relatifs aux differentes architectures qui peuvent supporter une application, d’autres concernant la sécurité en général des logiciels et enfin ceux concernant “l’humanisation “ de l’informatique.
