Education
- MSC Artificial Intelligence and Big DataEpitech2023Je réalise et développe différents projets en data science et développement full-stack, couvrant plusieurs domaines complémentaires. Côté machine learning, j’ai travaillé sur l’analyse de séries temporelles appliquées aux marchés financiers, notamment l’étude des tendances et comportements du marché boursier américain. Ces projets m’ont permis de manipuler des modèles de prévision, d’exploration de données financières et d’extraction de signaux pertinents. En computer vision, j’ai exploré des cas d’usage liés à la détection et à l’analyse d’images, en mettant en œuvre des modèles de deep learning pour résoudre des problématiques concrètes de classification et de reconnaissance. Enfin, sur la partie développement web, j’ai conçu plusieurs applications complètes, notamment une application de time management permettant l’organisation et le suivi des tâches, ainsi qu’une plateforme liée aux cryptomonnaies intégrant des fonctionnalités de suivi et de visualisation de données en temps réel.
- Bachelor's degree in Mathematical Engineeringuniversity of bordeaux2021J’ai acquis une solide base en programmation avancée en Python et C++, me permettant de concevoir des solutions performantes et adaptées à des problématiques complexes, aussi bien en data engineering qu’en data science. Je travaille régulièrement sur le traitement d’images, en explorant des techniques de vision par ordinateur et de deep learning pour l’analyse et l’extraction d’informations à partir de données visuelles. Mes compétences incluent également l’analyse de données et l’optimisation, avec une approche orientée performance, qualité des résultats et amélioration continue des traitements. Sur le plan théorique, je m’appuie sur des bases solides en algèbre linéaire et en modélisation informatique en Python, qui me permettent de comprendre, construire et optimiser des modèles algorithmiques efficaces.
