I'm passionate about data and technology, with seven years of experience turning raw data into real business insights.
I've worked in e-commerce, retail, and marketing, both in multinational companies and startups, always focusing on
making data meaningful and actionable.
My expertise includes SQL, Python, and visualization tools, as well as data quality, ETL, data modeling, Machine Learning, and LLMs.
I love hands-on work—cleaning, organizing, and analyzing data to create dashboards, reports, and models that drive smarter decisions.
