If I'd have been interviewing you we'd have talked about those two projects a lot. Especially the OS kernel :)

I currently have two hobby projects "in development". An bot trader (it broke even over 6 months with pretend money).

And a logic analyser using a Raspberry Pi Pico board and the excellent sigrok software - this project took a baby step to being non hobby when another dev found it and raised some issues.

Don't stop with the hobby projects
