What I'm looking for

I'm looking to build practical data, analytics, and AI solutions, learn new technologies, and apply Python, SQL, and machine learning to real-world problems.

I'm studying Data Science while building practical analytics and machine learning projects that turn raw data into useful insights.

In my Wine Reviews Analysis project, I analyzed 130,000 wine reviews, using data cleaning, segmentation, categorization, SQL, SQLite, Python, and pandas to identify patterns in expert ratings.

I also explored the relationship between generative AI use and academic performance, comparing machine learning models with R², RMSE, and MAE. For customer churn prediction, I evaluated Logistic Regression and Random Forest models using accuracy and recall.

I enjoy learning new technologies, building projects from scratch, and applying data and AI to real-world problems through Python, SQL, Power BI, and visualization.
