I am programmer ever since I remember. My father bought me Atari 65XE when I was 12 years
old, and that's how I got started. I was bored just playing games, so I started to write programs
in BASIC. When this language was too slow for me I learned Assembler. I created different
programs for my friends, for school. Then there was PC, DOS, Windows 3.0... 1995 - and found
out what Linux is all about. I started to learn C...... my CV is testimony to the continuation of
development of my skills....
