Summary

10+ years experience in data science in automotive. PhD in machine learning for thermodynamic control, more than 3 years experience in fullstack software development with SCRUM, 2 years experience in technical and budget responsible project management (Kanban) for Japanese and German car manufacturers like Mercedes AMG, Nissan, Mitsubishi.

My passion for data and all the, beforehand unknown, findings generated from data analysis raise my enthusiasm for the data science. Either working focused on exciting projects in a team or leading engineers and scientists within complex projects generates happiness and personal well-being. Even though I love trying to find the optimal solution, I’m always focused on the project goals and best price for value output. Due to my engineering background, my greatest expertise can be found in data science for technical systems.
