Hi, I’m Giulio D’Errico: data enthusiast, Tableau developer, knowledge sharer and lifelong learner.

With a background in Bioengineering and a passion for both logic and creativity, I found in data visualization the perfect space to combine mathematical thinking, coding, and design.

I use coding as a reasoning tool, breaking down and reconstructing datasets to uncover patterns, anomalies, and insights that matter.

For me, Tableau is not just a BI tool: it is a creative environment where I can explore, experiment and bring abstract data to life through engaging and intuitive visuals (and also have fun).

On this blog I share dashboards, visual experiments, practical tutorials and technical notes.

This space is both my personal archive and a knowledge base designed to help and inspire others facing similar challenges, to make a positive impact on their learning and growing data journey.

Beyond the keyboard, I’m a trained saxophonist. Music taught me collaboration, attention to rhythm, and how to listen: essential skills that I carry with me in every project and that shaped the way I relate to others.

If you're passionate about data, design, logic and creative problem-solving, you're in the right place.

Welcome!
