Hello, I am Balazs Koren

Husband of one, father of three, teacher of many...

Father I am proud father of three. Everything I do would be impossible without the support of my lovely wife. It is the best thing in my life to have a loud and cheerful home. I admit it is sometimes tiring a bit. :)

Teacher When I am working, I do something related to teaching. Being a father means that teaching doesn't end when I am getting home. Being a teacher is a profession 0-24. In the last 2 years I travelled around the world to bring the GeoGebra community closer together. Teaching how to use the software, when to use it and how to get involved in the community.

Geek Yes, I am a geek. I am interested for every kind of gadget. Photography gear, laptops, tablets, smartphones, etc. Founded androidportal.hu with 2 friends, the site is now one of the biggest Android community site in Hungary. But I do use Apple products too, iTouch.hu is the iOS part of me.

Hobbies Every kind of sport what has to do something with rolling or sliding, it is likely, that I tried it. Inline Skating, freeline, windsurf, sailing, snowboard, ski, just to name a few examples. I like to take photos, traveling, concerts, portraits, etc.
