• Constructed a variety of Supervised and Unsupervised machine learning models with 85+% accuracy.
• Produced descriptive data visualizations and interpreted findings in documentation and presentations to tell coherent stories to technical and non-technical holders.

• Developed and presented a predictive model using supervised machine learning algorithms to be able to determine if the next pitch any MLB Pitcher throws will be a fastball or an off-speed pitch.
• Performed feature and data analysis of pre-pitch categorical and continuous feature variables to determine whether each of these variables are statistically significant to determining whether a pitch is a fastball.
• Used GridSearchCV to hyper-parameterize the features of our Classification Models. Resulted in a model accuracy of 66%, which is an improvement of 14% from initial machine learning model’s baseline accuracy of.

• Examined client, Big Mountain Resort, current facility features and compared them to other competitive markets to create a predictive pricing modelto investigate if the company can raise resort prices and by how much.
• Developed baseline performance machine learning model to as a comparator for other subsequent models built. Designed models built to gain insight into what Big Mountain's ideal ticket price could/should be, and how.
