I really care about technology and what it represents in our society. I have been working with such things for about a decade, since technologies applied in industry, such as PLC and microcontrollers, as high-level languages designed for enterprise solutions, like Java and .NET. I believe that people solve problems, not technologies, and there is no reason to be held hostage by frameworks or even libraries, as long as you have a strong grounded concepts both provided by theory and experience.

Software Developer at SAP Latin America Labs. I received the Information Systems bachelor degree in 2017 and the Big Data, Data Science and Data Analytics graduate degree in 2019. In 2021 I got my Masters degree in Applied Computing in the Graduate Program at the University of Vale do Rio dos Sinos (Unisinos). Nowadays, I work as a Software Developer , solving business problems using cutting-edge technologies and guiding other developers in the software development process. Also, I do research in Software Engineering area, seeking for developing tools capable of improving developer’s productivity and bringing to them a better life quality. Aiming to improve myself everyday, I'm currently doing a MBA in Leadership and Management 4.0.
