My passion is hacking, that is why, for me, my job is more than my profession, it is my hobby and my philosophy of life. In my career, I have worked with international clients from different sectors such as banking and finance, telecommunications, government agencies, training, superstores and presence in countries such as Spain, Brazil, Colombia, Peru, United States, Chile, Argentina, Uruguay, Mexico, United Kingdom, France, Canada… I currently work as Senior Security Consultant at Telefonica. I like to enjoy nature on the beach and in the mountains, I practice surf, body surf, gym, meditation, trekking and mountain bike. Whenever my investigations and offensive security training allows me to.
