about me

I am married, I have a beautiful wife Kate who is a teacher at Primary School in Warsaw. We like traveling and visiting foreign countries and cities. We spend our leisure time playing the board games, reading interesting books or watching good movies.

At work I believe I am hard-working, I am able to organize and plan the work. I am flexible, I am able to adapt to new conditions and new environment. I am always happy to learn new technologies and all the time I try to keep an optimistic approach. I don't regret the failures but only missed chances.

I spend free time in an active way. I'm keen on running and riding bicycle as well as trekking. From time to time I participate at running events in Warsaw - mainly 10km, half-marathons and marathons.
I am also fascinated by Spanish language and culture. I speak Spanish and all the time I try to improve my language skills. I am great fan of Carlos Ruiz Zafón and I am keen on reading his books in Spanish. I speak also a little German.

And eventually I have just started writing a blog.
