In a team of five, we designed, tested, and developed a go-kart within just one semester, with the limitation of purchasing only the motor, steering wheel, tires, and wheels. We engineered all mechanical components as well as electrical elements such as wiring harnesses, connectors, and lighting systems. Using CAD software, we modeled the entire project while applying the technical knowledge gained during the course. The project involved iterative testing and improvements to ensure optimal performance, safety, and functionality, showcasing effective teamwork and practical application of multidisciplinary skills.

During my initial professional internships, I applied the knowledge and skills gained in my studies to support the design and development of an injection mold for producing the mirror housings of the Nissan March. I conducted tests using 3D printing to validate prototypes and optimize the design before manufacturing. Additionally, I performed detailed studies and modeling using CAD software such as SolidWorks and CATIA, ensuring the mold’s precision and functionality met the required quality standards.
