Hi! I’m Marco!  

As you may have already noticed, I am a Freelance System Engineer but that’s not all about me! I enjoy life in several ways and little things make me happy. I escape the daily-life now and then by traveling and taking photos.  It’s a way to keep my feet on the ground and to focus on values that matter the most. 

I like sports, I like doing sports! Don’t ask me about any football matches that had happened during the last weekend, I don’t care! I do swimming and I play tennis. I like also climbing and biking.  I am not professional at any of them, I simply like the different challenge that each sport set for me.

I love hiking because mountains remind me how little we are and how perseverance and dedication can lead anybody towards a goal. I am also a novice diver looking forward running into Captain Nemo during my next dive.

I keep learning from people around me, from books and life experience. Life is a continuous journey of amazing rides and challenges at times, why not joining it?

If you wish to stay in contact, drop me a line!

Thanks for passing by! Take care!
