About Sondoss

Data Science Engineer and PhD in Artificial Intelligence, I design data and AI solutions to transform complex business needs into reliable and operational decision-making tools.
Specialized in predictive modeling, data analysis, optimization, and model development (ML/LLM), I have worked in an AGILE environment with industrial clients and public authorities on high-value-added projects.

I master the entire data chain: collection, preparation, modeling, evaluation, visualization, and integration into real-time applications.
I also have strong expertise in creating interactive dashboards (Power BI, Tableau, Python) to improve understanding, steering, and decision-making.

Curious, rigorous, and results-oriented, I combine technical expertise, business understanding, and the ability to deliver concrete, high-performing solutions tailored to users.
