I have strong knowledge in RFID/NFC technology as I have been working in that sector since 2007. I have been interested about crypto currencies since 2013 when I made for myself script to help find best crypto pair for trading.
I have strong knowledge in programming with Perl and unix systems (Solaris, openSuse, Ubuntu, Fedora, Manjaro, open BSD), because I have been working with those around 15 years.
My first touch to programming was when I was just a kid (don't remember age, but around 10 I believe), I try to do some programming with MSX. It was mostly copy & paste code from books, but any way it spark fire in my soul. Later age I studied C and C++. Seriously programming started with Java and then I found Perl, which I prefer most of all.
