• Data Scientist

  • Feb 2018 - Jun 2019

  I was responsible for designing projects that used machine learning techniques to leverage the clients' performances; I was also responsible for looking through the clients' data and communicating interesting insights that can be used to explain the patterns of certain phenomena; I created machine learning pipelines - from data pre-processing to model validation - that could be scheduled or triggered on demand, resulting in models to be deployed on a proper environment; I communicated the statistical models' capabilities to non-technical stakeholders in simple ways by showing the impact on a macro perspective, which is closer to the business and usually easier to comprehend; I collaborated with internal data science/machine learning courses and seminars, aiming to strengthen our team; I had lots of fun :) Show less
