I have an initial background in accounting and management (DCG degree) and three years of experience in this field before successfully transitioning to software development. This transition was validated by the demanding training at École 42, founded by Xavier Niel, at the 42Nice campus, which allowed me to deepen and certify my IT skills.

- Digital Technology Architect., Programming / Computer Developer, General42 Nice2023Tronc commun Afin de valider mon apprentissage autodidacte, j'ai entrepris plusieurs projets à l'école 42 dans les domaines suivants : C, CPP, Script SH, Python (y compris Django, NumPy, Numpy+Matplotlib), et Docker. - Dans le cadre du projet final réalisé, j'ai travaillé en FullStack nodejs (NestJS, Prisma (PostgresSQL), React, Mui, Auth JWT + API). - J'ai réalisé un projet de serveur HTTP en CPP à partir de zéro, en utilisant les sockets, inspiré du fonctionnement de nginx. J'ai également mis en place des tests unitaires, en utilisant les Github Actions. - J'ai opté pour un projet de RayTracing en C, où je dessinais des formes 3D pixel par pixel à l'écran, avec calcul de lumière et d'ombre. Cela m'a permis de pratiquer l'intégration de formules mathématiques dans le code. Ces réalisations ont été des expériences enrichissantes qui m'ont permis de consolider mes compétences dans divers langages et technologies, ainsi que dans la gestion de projet et le travail en équipe.
