About Me

My Avatar

I'm a recent engineering graduate specialized in Data Science and Artificial Intelligence, now focused on Data Analytics and Business Intelligence.

PL-300 certified, I specialize in transforming raw data into actionable insights through data modeling, interactive dashboards, and clear visual storytelling. I have hands-on experience designing end-to-end analytical solutions, from data preparation and SQL querying to building Power BI reports that support strategic decision-making.

I'm passionate about helping organizations become data-driven by delivering reliable metrics, meaningful KPIs, and user-friendly dashboards that create real business impact. I believe data is a powerful lever for performance and innovation, and I aim to turn complex datasets into clear, valuable insights that drive smarter decisions.
