I was born in Madrid, Spain, in 1996. Since I was a child I knew my future was in front of a computer. I was attracted to computer security right after I started college.

I use this blog with a double purpose. I want it to serve as a source of constancy and motivation to continue learning. But I would also like to be able to share the knowledge I am acquiring with all the people who want to learn, and thus bring the wonderful world of hacking closer to those who don’t know it. Just like they did with me.

I write this blog in Spanish and English. In this way I can reach more people with the knowledge I am acquiring, and I can improve my writing in English.

I have a degree in Computer Engineering and a master’s degree in ICT Security.

If I had to choose a country, it would be Norway. I was there for a while and fell in love with its cities and inhabitants. However, I love to travel, and I would very much like my work to take me to many corners of the world in the future.


In 2019 I decided to voluntarily quit my job in Madrid and move to Dublin to get out of my comfort zone and improve both personally and in my career as a pentester. Once there I started looking for work and after assessing several companies I found my place next to a team of security experts in a large corporation. This opportunity is allowing me to quickly increase my knowledge and improve my English skills. However, I continue to work hard on my own with hackthebox, pentesteracademy and computer security books such as The Hacker Playbook saga. In addition, I have in mind to obtain the OSCP certification in a few months.

In this blog you will be able to see articles and PoC of those interesting topics of computer security that I learn in my work or in my studies.

But not everything is hacking: in my free time, I have a large number of hobbies. Among others, I practice martial arts (taekwondo and hapkido), I perform aerial acrobatics in a circus school, and make woodworking and pyrographs.

I hope you like my blog, and if you have any questions or suggestions I would love to help you, so I encourage you to contact me.
