Trying to work on interesting things with interesting people.

About

Economics

Universidad Autónoma de Madrid

Mathematics

Universitat Jaume I

My purpose in life is to give back to society everything it has given me, creating impact and inspiring others, while being concerned about the future of human beings both as individuals and as a collective.

I have always been connected to technology. When I was younger, I was obsessed with understanding how smartphones worked. I compared devices, watched tech channels like Topes de Gama on YouTube, and by the age of 12 I was already exploring iPhone and iPod Touch hacking to install customizations and apps outside the App Store.
