About

Half of me is a computer #nerd working as #gamedev engine #programmer at #Ubisoft in #Montreal #Canada where I live. Not really a gamer. I run my own #linux servers and is into #retrocomputing, #demoscene and #opensource and anything #science. I mostly listen to #ebm, #industrial, #metal and #synth. I have a weak spot for #art. The other half of me doesn't hash tag.
