In my experience, I've primarily used Python for data analysis, leveraging libraries such as Pandas for data manipulation and Matplotlib for data visualization. Additionally, I've worked with MySQL for database management and querying. For instance, during my internship at Exposys Data Labs, I was part of a project that involved analyzing customer data to identify purchasing patterns. I used Python to clean and transform the data, then utilized MySQL to query the database for specific insights. Finally, I created visualizations using Matplotlib to present the findings to the team, which helped in making data-driven decisions for marketing strategies.
