In our industry traditional titles are exhausted so early so here's localized quantification [0] (on a lighter note, no disrespect to OP or anyone). I'm in KSD title range.
Real senior developers with lots of experience are usually shown the finger in our industry. There’s no such title to reflect 57 years of experience; i’ve heard it unofficially refered as baggage
Sadly that is a very common situation. Thus even more fitting to celebrate those who are still working, learning and enjoying their programming careers.
I'm a young pup compared to the OP - started programming in 1973 (unless you count the DigiComp I..) My children had a license plate frame made for me that has has my current title (at least around the family): Granddaddo, Gerihacktrics Specialist! (At work I'm currently a Principal Software Engineer. Last gig, I was Senior Principal. Would be fun to make Fellow one of these days.)
What your current title?
