Felipe has a background in academia which helps him during the research and development of deep learning models. Combined with his knowledge of Python and ML libraries such as TensorFlow, business intelligence (BI) is a significant part of his interests. He has experience using tools such as Looker, Tableau, and Microsoft Power BI. For Felipe, science goes hand in hand with the engineering aspects. For that reason, he always looks at ways to use the best software development practices.
