My name is Matheus Zani. I am a Brazilian citizen, with a bachelor`s degree in Production Engineering at the Polytechnic School of the University of São Paulo in 2019 (best engineering and technology faculty in Latin America according to the 2019 QS World University Rankings). My last professional experience was at Mastercard (Brazil), in the Customer Fraud Management area, where I was able to improve my analytical skills, especially in data engineering and data analysis. My activities involved: handling large databases (using SQL language); handling cubes in excel in order to retrieve data and organize them in Pivot Tables; calculation of indexes (general ones and KPIs) related to authorization, fraud and chargebacks of credit card transactions; creation of dashboards using Excel+VBA+PowerPoint, PowerBI and Tableau; annual presentation of the Mastercard Academy’s Fraud Principles course for Card Issuing Entities. In addition, I also have familiarity with Machine Learning and the Python language (and with its ML and mathematical libraries), which I used in my thesis - whose long title is Comparative analysis between two machine learning approaches - logistic regression and random forest - in a fraud detection model for e-commerce credit card transactions. The thesis was written in conjunction with my university and Mastercard, and the use of masked data from the latter was authorized. Having exposed the above content, I am looking for a position, outside of Brazil, as a data analyst, data engineer, data scientist or similar/relative. My preference is to find a job in a country located in Europe. I have already visited more than 24 countries and I am very interested in learning about other cultures and meeting/working with people from other countries. In addition, I am in the process of obtaining Italian citizenship - and I aim to complete this process by staying 3 months in Italy in the first quarter of 2021. Therefore, I would only need help to obtain a work visa for 2020 and for the beginning of 2021. ©
