Some of my greatest achievements as a Data Scientist include: - I developed a machine learning model for predicting the power draw of a SAG mill. I managed to reduce the power consumption by 1.5% - I developed a pricing model for a bank, which calculated the price for all products for each customer. The model allowed to automate the process of evaluating customer risk and determining the prices of the products. The number of customers evaluated per day increased by 12% and the income by 0.8%. - I developed an economic evaluation model considering risk for a big project of a mining company. The model allowed us to evaluate more than 50 mining plans. The model included predictive model simulation and real options.
