Hello, I'm Mario Nikolaus, a Javascript Developer based in Zagreb, Croatia. My passion for technology started at very early age and for more than 15 years I have been working on my front-end skills. A variety of interests led me to become active in numerous volunteer-based projects.
In my free time I am a big fan of watching and playing all kinds of different sports (played volleyball professionally for 15 years), all other group activities, photography and travel.
I strive to work in dynamic and stimulating enviornment with people who are passionate about what they do and give much attention to design details, clean code and reusability. I am always eager to learn new things and I am not afraid of challenges. I am a team player and I am always ready to help my colleagues.
