À propos de moi


Learn and teach.


Hallo, wie geht es dir?

Ich heiße Oscar Marques.


Здравствуйте, Как поживаешь?

Mеня зоbут оскар маряес.


I'm especially interested in vulnerabilities analysis and developing.

I also study this topics not related to computers:

- History, weapons, military systems and tatics, radio communication, planes, hunting, camping, music, religions, languages.

I have some language skills, I speak portuguese, english and spanish. Now I'm studying german, dutch and russian.
I hope to learn arabian, chinese, japanese, french, italian, swedish, norwegian, finnish, turkish and greek someday.

I'm trying to play music, trying to boost some sounds out of my flutes. I like black and folk metal, andean music, classical.

I like some games: chess, AA, ET Wolfenstein, Battlefield. If you want to have my nickname just let me know.

I 'm a crazy coder, smart sysadmin, dangerous and insane guy but I can love you...

Pourquoi je suis sur Couchsurfing


I went to a CS meeting in Mercadinho, Laranjeiras - Rio de Janeiro - Brazil.


Meeting foreign people to learn more about their country, culture etc..
