They identify as agender and asexual, as they find things like sexuality and romance bothersome and illogical. They spend most of their time in their room in front of one of their computers (all of them selfbuilt, of course), programming and hacking for fun. They are also interested in mathematics, physics and chemistry. If you're not versatile in any of these topics, don't even bother trying to talk to them.
