Welcome to my Data & BI Portfolio

Junior Data Analyst & BI Developer | Developing expertise in Data Visualization & Storytelling

Welcome to my GitHub!
I’m a Junior Data Analyst and BI Developer with a strong background in eCommerce and digital marketing, now focused on data visualization, dashboard design, and business insights.

After several years as an eCommerce Specialist, I developed a deep understanding of how data supports decision-making — from user behavior to performance tracking.
This evolved into a passion for turning complex datasets into clear, visual stories with Tableau, Power BI, and Excel.
