Hello! Welcome to my portfolio :)
This is where I share my journey in the world of data. It all began in 2023 when a YouTube channel called Alex Τhe Analyst sparked my curiosity and motivated me to explore more of this world. Working with data made me realize how impactful and valuable it can be. From uncovering patterns and creating clarity from complexity to presenting information in an approachable way.
I started by learning tools like Excel and MSSQL, then expanded to Tableau, Power BI, and Python to clean, analyze, and present data in ways that make it accessible and meaningful.
Thank you for visiting, and I hope you discover something new!
