About Xavier

Ingénieur en sécurité applicative depuis 6 ans, je dispose d'une expérience riche dans la sécurité d'applications à forts enjeux économiques. Je suis compétent pour réaliser des audits de sécurité sur des applications web2 telles que des applications financières, des plateformes e-commerce, des solutions SaaS, des ERP, tant en mode boîte noire que boîte blanche. De plus, je possède aussi une expertise dans les audits d'applications web3 (EVM et Solana).

Ma capacité à m'exprimer couramment en français et en anglais me permet d'assurer une communication fluide, facilitant ainsi la collaboration sur divers projets d'audit, de la définition des cibles jusqu'à la mise en place des mesures correctives.

Je ne suis disponible que pour des périodes courtes (maximum 2-3 semaines).
Je suis en mesure de vous accompagner tout au long du processus d'audit et de fournir un rapport détaillé.

N'hésitez pas à me contacter pour discuter de vos besoins en matière de sécurité applicative et pour envisager une collaboration fructueuse.
