Notable Skills
- Machine Learning Implementation
- Data analysis and Interpretation
- Data visualizations
- Data Reporting
In this project I analyzed a Human Resource dataset with information of employees who stayed and left an organization. The purpose of the analysis is to analyze the significant factors that drive employee turnover, by performing survival analysis, to then implement a Supervised Machine Learning classification model to predict whether an employee is going to quit, and analysis its main features to discussed how to improve the causes for quitting.
Notable Skills
- Data extraction and Transformation
- Data analysis and Interpretation
- SQL Efficiency
- Problem Solving
In this project, I studied the patterns of FitBit users during their product usage. I considered the number of steps as an estimator of their physical activity, and weight, BMI (Body Mass Index), and gender as estimator for their BMR (Basal Metabolic Rate). The goal was to determine if whether users achieved their weight loss goals, as well as suggestions to improve clients-product relationship.
Notable Skills
- Data analysis and Interpretation
