I'm a trans guy working as a professional software eng, and yeah, I'm stealth.
I'm sorry I (and presumably many others) don't act as real life representation save for these online spaces! I promise you we are out there, and being trans doesn't have to be a barrier.
I don't think I'd be in hot water if I came out or anything either; I just work at a company that is largely older and conservative so I'm just personally being extra cautious in not wanting to add any unnecessary social tension.
