Biologically and functionally speaking, he's whatever and everything. Practically speaking, he chooses to have a dick and look like a big muscular man that looks nothing like his previous form (so its even more deliberate), so it seems the only thing that survived his ascention was his gender identity.
You're saying you got out of college ten years ago, and worked for exactly one company that entire time, and you can't say who it was or what you did because of an NDA?
Even if you don't mention who you signed it with? There's quite a bit difference between saying "I've signed NDA" and "I've signed NDA with company (name)"
Not normally, that wouldn't make much sense. It's easier to just say you signed an NDA and anyone with sense knows you're not allowed to talk about the work.
