Who I am?

Hi, I'm Juan Calahorro Villar Computer Engineer, developer, programmer and graphic designer.

The best way to introduce myself is to show what I do, what I like and what I am capable of. I may be a programmer and graphic designer, I will not announce myself as the best in my field since I am not, maybe someday I will be. I just hope you like my work, and if so, that you consider me to carry out any of your projects or offer me a job in your company.

Not only am I Technical Computer Systems Engineer and Graphic Designer, I have also specialized in my hobbies, met other jobs, and tested different experience. If I didn't, life would be very boring.

  • Collector and comic book fan. I have always been fascinated by comics, superheroes and science fiction, and I have always liked to collect from books, comics and movies, to figures and other related merchandising, and following this hobby, for some years I have discovered another of my big hobbies: cosplay, become my favorite characters for a while, and go to events to share this hobby with my friends.
  • Rock and Music. I am continuously listening to music, mainly rock in all its versions: hard rock, punk, metal, heavy ... with my ariculars, or on vinyl if I am at home.
