About me

A small introduction about myself

Fidel Montesino

Freelance Android & Web Developer

My main goal is to learn, keep growing and become a bit better developer every day.
I consider myself a self-demanding person, so I always try to do my work as best as I can.
When I was 9 years old, a Visual Basic book fell in my hands and I started coding small programs. At the age of 11, I already had in mind studying Computer Engineering and becoming a software developer.
Programming is one of my greatest hobbies, as well as traveling around the world and getting in touch with new cultures.
I cannot imagine life without music, and it gets better if I can see it live.
