About Julien

Vous cherchez à accélérer vos développements, automatiser vos analyses ou fiabiliser vos modèles de simulation ? J'accompagne les équipes d'ingénierie dans leurs projets de simulation, d'analyse de données et de développement d'outils techniques sous MATLAB et Python afin d'améliorer leur efficacité et leur prise de décision.

Ingénieur Performance Véhicule avec plus de 13 ans d'expérience en Formula E, IMSA et IndyCar, j'ai contribué à des programmes ayant remporté les 500 Miles d'Indianapolis (2025 et 2026), plusieurs championnats IndyCar ainsi qu'un titre mondial en Formula E.

Ma valeur ajoutée réside dans ma capacité à transformer des données complexes en solutions concrètes : développement de modèles, corrélation simulation/essais, optimisation de performances, automatisation de workflows, création d'outils d'ingénierie et aide à la décision technique.

J'interviens régulièrement sur des projets de :
  • simulation et modélisation
  • analyse et visualisation de données
  • développement MATLAB et Python
  • automatisation de processus d'ingénierie
  • optimisation d'algorithmes et d'outils internes
  • validation et corrélation de modèles.

J'aime intervenir sur des problématiques techniques complexes où une approche rigoureuse, pragmatique et orientée résultats permet de faire gagner du temps, de fiabiliser les analyses et d'améliorer les performances.
