I work as Linux administrator, I create embedded designs and I write software (preferably lowlevel, parallel, respecting the UNIX philosophy, from the field of signal processing, networks or cryptography). I can quickly introduce myself into almost any programming language or technology and produce drafts of seemingly impossible things. You can find some of my projects below.
I have finished bachelor program General Computer Science (thesis) and master program Software and data engineering (thesis) on Charles University. I was an active member of brmlab, the Prague hackerspace. Though I'm a "computers guy" by profession, my interests are much broader, including everything from biology over physics to engineering.
I ride bike as the only mean of commuting everyday. Once a while I go to a longer biketrip too. You can join me if you wish :)
