Projects Deliverables1.HOUSING IN MEXICO: I analyzed 21,000 property records to determine if real estate prices are influenced more by size or location. Tasks included importing and cleaning CSV data, creating visualizations, and examining variable relationships using correlation.2.APARTMENT SALES IN BUENOS AIRES: I built a linear regression model to predict apartment prices in Argentina. I created a data pipeline to impute missing values and encode categorical features, improving model performance by reducing overfitting.3.AIR QUALITY IN NAIROBI: I developed an ARMA time-series model to predict particulate matter levels in Kenya. I extracted data from a MongoDB database using pymongo and improved model performance through hyperparameter tuning.4.EARTHQUAKE DAMAGE IN NEPAL: I constructed logistic regression and decision tree models to predict earthquake damage to buildings. I extracted data from a SQLite database and identified biases in data that can lead to discrimination.5.BANKRUPTCY IN POLAND: I created random forest and gradient boosting models to predict company bankruptcies. I navigated the Linux command line, addressed imbalanced data through resampling, and considered the impact of precision and recall on performance metrics.6.CUSTOMER SEGMENTATION IN THE US: I built a k-means model to cluster US consumers into groups. I used principal component analysis (PCA) for data visualization and created an interactive dashboard with Plotly Dash.7.A/B TESTING AT WORLDQUANT UNIVERSITY: I conducted a chi-square test to determine if sending an email could increase program enrollment at WQU. I built custom Python classes to implement an ETL process and created an interactive data application following a three-tiered design pattern.8.VOLATILITY FORECASTING IN INDIA: I developed a GARCH time series model to predict asset volatility. I acquired stock data through an API, cleaned and stored it in a SQLite database, and built an API to serve model predictions.
