Got a decent background in several databases and at least heard about every script language out there. But I only speak Java and Perl proficiently. I dabble in ECMAScript, Pascal/Delphi, C(++), less so in Python or Ruby and try to ignore C# and Go. But in the end, I will talk in whatever is needed to command the uprising machines!
P.S.: Secretly in love with the more obscure workings of PCRE... But don't tell anyone!
