Data exploration, cleaning, and integration to uncover insights into product sales trends, customer behavior, and sentiment analysis of reviews. Key findings were visualized in an interactive dashboard, highlighting KPIs and actionable business recommendations.

The insights aimed to provide a detailed overview of the competition, athlete performance, and event statistics.

HOUSING PRICE/MACHINE LEARNING

The project aimed to develop a machine learning model to predict the sale price of houses based on various features such as location, size, number of rooms, and other property characteristics. This was conducted as part of a Kaggle competition to enhance predictive accuracy using a structured dataset.
