      Developed an ensemble machine learning model combining a random forest regressor and gradiant boosting regressor in Python predicting proportion of students living in poverty based on school district characteristics that had an RMSE of 5% at the national level and was able to get under 3% at the state level. Using R, extracted then analyzed data from Twitter to find out who is the most popular Stoic philosopher on the platform. Participated in Titanic Kaggle Contest developing a machine learning model classification model in Python that predicts possibility of surviving the disaster based on passenger characteristics with an accuracy of around 78% (within top 15% competing at the time).
