Questions about a Portafolio

Hi Everybody! My name is Paola (but you can call me Itachi) and I’m an Industrial Design student at “Instituto Tecnologico de Estudios Superiores de Monterrey” ITESM in Monterrey, Mexico and also I like anime, manga and all that japanese stuff XD. I’m new at this forum.

I want you to ask something that maybe its a little bit stupid but, I dont know how to start my own Portafolio to search for a job.

¿Anyone can help me with some ideas to how to start?

Thanks everybody!
