I’m an aspiring Data Scientist and AI practitioner with a background in Computer Science and more than ten years of experience in digital solutions. Currently training in AI & Data Science at Masterschool, I build data-driven projects using Python, SQL, Machine Learning, and Data Visualization.
My portfolio includes exploratory data analysis, predictive modeling, clustering, recommendation systems, and computer vision projects, with a strong focus on clean, reproducible workflows and model evaluation. I enjoy turning complex datasets into actionable insights and creating solutions that combine analytical rigor with practical business value.
I’m particularly interested in machine learning, computer vision, explainable AI, and the application of data science to real-world decision-making.

I find beauty in both nature and numbers. When I’m not analyzing data or creating vector images, you’ll find me designing cakes 🎂, tending to my garden 🌱, or practicing yoga & tai chi 🧘♀️. Creativity and logic are the two forces that shape my world.
