My bad, I'm not a native English speaker.
I've always though that about tinkering as in "being in love to work with inner working of things and understanding the internals, mastering stuff". Nothing pejorative.

More in line with your definition would be artisan or craftsman; although fwiw craftsman can have a negative slant in modern (American) English as some people use it in lieu of blue-collar workers.
