    About me Below are listed programming languages, technologies, frameworks, engines and tools which I've used and projects in which I was involved. Beside that information I would like to also mention that I'm addicted to Open Source. My working station is based on the Gentoo Linux. The Linux is the system where I feel myself at home.
