I have spoken a few times. My favorite self intro is:
Slide with title "about me"
Next slide: "who cares"
Then I say "you came here to learn about <topic>, not me. Feel free to Google me if you want".

* someone has read or at least scanned my speaker bio
* folks want to get straight to the content
* my expertise is shown by the fact I'm speaking and the content I'm conveying
But maybe I'm wrong.
Probably not.
As I wrote in another comment, a quick context-set and contact information in probably useful but quick is the operative phrase especially for any background that isn't directly relevant to the material at hand.
I'll do it after, if your talk catches my attention.
This is why I now love attending talks remotely. If you annoy me, I can mute you and focus on something else and unmute the stream when the next speaker comes up.
"you came here to learn about <topic>, not me. Feel free to Google me if you want. Just please keep in mind that all teenagers make mistakes. It's not my fault you only made boring mistakes."
To make it work, you need to deliver the last line while seemingly preoccupied with something presentation-related. Otherwise, it seems hostile. An example could be as simple as pretending to change settings on microphone or moving one slide back, then forward twice. It conveys it was intended to be inner monologue
