Data Scientist

Hello, my name is Alessandra Recordare and I am 26 years old. I have a bachelor's degree in computer science that allowed me to learn the basics of programming, studying languages such as C, C++, Java, JavaScript, OCaml, C#, Python, SQL, R. I later obtained a master's degree in Data Science and Business Informatics at the University of Pisa. During my Master's degree I focused particularly on data analysis, data mining and machine learning, in fact in the two years following my degree I worked as a researcher at the CNR in Pisa in a research group dealing with cybersecurity on social networks, so I used to working with very different types of datasets, which most of the time were very large, mainly using Python and popular machine learning libraries for predictive modeling such as PyTorch and TensorFlow.

I am now looking for new professional opportunities as Data Scientist, in Italy or full remote.
