Hello, my name is Konrad :)

I have been programming professionally for years and more as a hobby.
While in game industry I had opportunity to work on low-level cpu and gpu programming with focus on high performance. As a tool and graphics programmer I worked closely with people from other disciplines, graphics and sound artists, localization team, UI programmers etc.
In my free time I play with electronic, 3D printing, game jams and sometimes security CTFs/wargames.
