Master in Computing Science at Federal University of Rio Grande do Norte (2018-2020) when I have been involved with the development of solutions in the area of software repository mining, applying data manipulation, statistical testing, and machine learning models to understand the impact of software engineering practices on the quality of open-source projects. During this time, I acquired some experiments in Python libraries for data science, such as Pandas and Numpy for data manipulation. Scikit-learn and Scipy for machine learning and statistical tests.In the past four years developing financial and banking solutions for B2B and B2C. During this time, I acquirer experience in Java and Kotlin development, using Spring Boot as the main framework and knowledge in relational and non-relational databases, reactive and non-reactive data streams such as Kafka, development using an event-driven paradigm, and integrated and unitary testing framework. In addition to technical knowledge, I developed knowledge about financial and banking business, working with acquirer and subacquirer relationship, payment process, food and meal voucher regulations, fixed income applications, internal bank transfers.
