Over the last year or two @jeffgeerling.com has definitely become one of my favorite technical YouTubers. One of the few channels where I watch almost every video. Nice interview with him posted on Raspberry Pi's site. Congrats! www.youtube.com/@JeffGeerling

Do you think he has something to share for self-taught, aspiring programmer?

Definitely, he writes lots of docs and explains things very well. There are probably better sources for starting out but it is probably still interesting/useful.
