About me

Hi, my name is Łukasz Czerwiński. I am a C++/Python developer with some experience in math. For me, programming is a passion and not a job. I am currently working as a contractor for NYSE financial company as a Senior Software Developer. All of my professional work is related to server/core applications which were implemented mostly in C++.

I am a proud member of Mensa Poland.
