Freelancer profile translated to English.

Description

Hello, I'm Marcel. As a mathematician by training, I've always been passionate about solving complex problems; today, I apply that analytical rigor to data science to help companies make informed strategic decisions.

My background in pure mathematics allows me to go beyond simply using tools: I understand the logic behind the models. This makes it easier for me to design, optimize, and create tailor-made data analysis solutions, adapted to the specific needs of each business.

I have solid technical experience in process automation (ETL/ELT), database structuring, and high-impact visualization using Python, SQL, and Power BI.
