About Me
My name is Alexandre Turgut Gulsoy.
I pride myself on my dedication, hard work, and adaptability to any organization I am a part of. My programming skills are versatile and span a wide array of languages such as Python, Java, JavaScript, and C programming. My specialties consist of SQL and Microsoft Excel to model, modify, and clean my datasets. And I prefer to use Tableau as my primary visualization tool to professionally present my data as interactive visual dashboards.

PROJECTS
European Sales Dashboard
Composed of 3 interactable visualizations, and one KPI, the dashboard represents the overall home/office product sales of all of Western Europe throughout the year of 2024. The metrics I chose to display are to provide the end user with multiple ways of analyzing the data provided. Finally, the KPI is to provide the end user with a complete picture of the total number sales, the profit made that year, and the number of customers the data is based on.
Adidas USA Sales
Comprised of 4 visualizations and 3 filters, the dashboard represents the product sales made by the Adidas brand in the US from December 2019 - December 2021. Each visualization presents the end user with a different metric by which to analyze the data. Finally, the filters were put in place to simplify the cross-analysis process between sales by product, region, and year.
Netflix Overview for 2025
Composed of 6 interactable visualizations the dashboard represents the overall number of movies & TV shows Netflix added from 2008 - 2020. The metrics I chose to display are to provide the end user with multiple ways of analyzing the data provided. I also provided the user the option to select a specific movie or TV show and see what its release date, duration, rating, genre, and description are.
