Professionally
Graduated in Information Sciences – Journalism by the UCH-CEU University of Valencia. Since first grade I discovered what was my first passion: radio. During the following years I did several programs in this media and directed my own daily sports program.
From then on, a change in my career took place that led me to the world of Tourism, studying a Master in Hotel Management that allowed me to work in fascinating places such as London, where I spent more than a year in an interesting project in charge of my own team.
During this time I was already very interested in marketing and content creation: I started several projects such as online video game magazines, niche thematic websites or restaurant and leisure websites, already in Barcelona.
Continuous readings and a great self-taught eagerness kept me active in the way of Marketing, which finally led me to do the Master SEO-SEM Professional at KSchool, where I consolidated my knowledge and discovered that SEO, a fundamental branch within marketing, was what I was really passionate about.
At present, I try to continue learning day by day in an industry that does not remain static even for a minute.
On a personal level
I am passionate about the world of online content, which has led me to dedicate myself to SEO. I like to keep up to date and read about Marketing and, specifically, SEO.
On the other hand, I love to communicate. I have a weakness for the world of radio – to go back to making a program is a dream for the future – as well as for the creation of content in all its forms.
Another of my hobbies is traveling: so far I have climbed to the summit of Mount Fuji in Japan, visited Pompeii, participated in a Holi party in Jaipur (India) and enjoyed much of the European continent, although I hope to explore many other places.
Sports, retro video games and good TV series are other hobbies of mine.
