Back to original languageAbout Maël
Flexible, enthusiastic, and friendly engineer with strong interpersonal skills. I would be happy to work on concrete projects, discuss and establish solutions, whether it's Python automation, Data Analysis, Data Science, or other IT fields.
Curious and always eager to learn more, a skill that is initially missing is not a barrier for me, but rather an additional motivation. You will not have to worry about my autonomy or my ability to work in a team.
