About my background, I've done a lot of C, slightly less Objective C, slightly less assembly, and far too much Perl for my liking. Also some Awk and sed, but that only ties in to being able to write proper Perl (sometimes). I don't really know what I hope to do wrt LJ, maybe a client, maybe backend code, maybe web interface stuff.
Who knows. But anyway, here I am, since you asked (well, kinda :), at your service.
