Campo Grande, Brazil

Professional working in information technology for over eight years. Even before entering the job market I was already interested in technology, I went to college at 2011 and graduated in Computer Engineering from the Federal University of Mato Grosso do Sul - UFMS at 2016, working in several projects throughout five years of course, such as: robotics, programming logic and computational optimization; I was regional finalist (MS) in 2012 of the Programming Marathon, 3rd Place by the ARARABOTS UFMS team at the Latin American Robotics Competition (LARC) - SEK 2012 Category; and finalist in 2015 of the Intel Embedded Systems Competition. My main academic interests are artificial intelligence, IoT and computer architecture; The latter earned him an article accepted by the Chilean Magazine of Engineering in 2020 about microprocessors using Quaternary Logic. I started my professional career as an intern at Tecsinapse - a company focused on the automotive sales market, with clients such as BMW, Mercedes and Audi; working on building web systems based on Java (EJB and Spring, HTML5 and JS) for helpdesk management. Migrating to the Product Innovation Lab - LIP, I started to work using technologies such as Javascript, React and Node.js. building cross-platform applications for the company's flagship CRM product for dealers, as well as creating and maintaining front-end components and libraries in Javascript, React, and their ecosystem. In 2015, I founded startup Indext, part-time, working in a variety of roles, including as an Agrotech-linked software project manager, as a requirements analyst, architect and software developer React using cloud services such as AWS. and Firebase. I completed my activities in September 2019 to take over the leadership of LIP - Tecsinapse. I always like to bring innovation to the work day using new technologies or making processes more productive. I like to take responsibility for project, taking it as part of me. I like to elevate user experience by creating products that are enjoyable to use; and also elevate the developer experience with libraries or tools that as mentioned earlier make your life easier.
