Mine’s been that way for a few years now. It’s an oblique reference to the “Tinker, tailor, soldier, sailor...” children’s rhyme and the novel “Tinker Tailor Soldier Spy” by John le Carre, one of my favorite spy novels. 

It also encompasses my hobbies and professional skills, hah. I used to have a longer version on my profile - I think it said “Tinker, tailor, builder, dancer, hacker, lover, thief.” But who has that kind of attention span, hm? ;)
