Introduction
I'm a Data Scientist, and Software Engineer, with 10 years of experience in the research, design, and implementations of Data Processing platforms. I am passionate about the challenge of crafting quality software able to transform big amounts of data in useful, and understandable insights, and I enjoy all the different phases of this quest, from data collection, to data visualization, going through data modeling, system architecture, algorithms design, and software deployment.
