Responsible for leading a group of 4 engineering students to design and build all parts of the prototype related to the Structure subsystem, like the roll cage and the body panels.May 2014 - Feb 2015: Team leader. Responsible for leading the whole team (20 engineering students) with the task of reaching the best results in the project.What is the Baja Project?It is a motivational project in which students have the chance to put in practice the knowledge acquired in classroom, by the development of an offroad recreative prototype, that must be marketed to an enthusiastic public. Each team is responsible for the conception of the project and the construction of the prototype, according to the SAE rules. Show less
