Life

The beauty of a transient world

Ex solo-traveler who loved to explore hidden gems and meet new people in hostels, where I learnt the beauty of bonding in a transient world. Now, I prefer traveling on my motorcycle, alone or with my closest people. Still hunting for hidden beauties, but now with more fun, freedom and lotta more adrenaline.

In an abusive relationship with my motorcycle

The epitome of fun. I am really sorry to my motorcycle for the abuse I put it through, but I have promised it that there's only glory ahead, and that's through Valhalla.

Throwing sophisticated haymakers

Martial arts was one of my life catalysts. As a kid I tried a lot of different sports, but none sparked like kickboxing did. After a few years I transitioned to MMA, and as of today, the journey has come full circle and I continue as a fan of the sports.

Touch some grass

To find balance in the fast paced life and the sins of software-engineering, I try to spend some time outdoors, reflecting and enjoying the simple things.
