For me, there are no "red" flags when looking at someone's public code.

I consider them as conversation items. I don't think anyone is expecting to see multiple completed products with 1k+ stars.

The worst case is, you waste time agonising over the quality of your code and either: don't publish, or no one even looks at it (highly likely)

You're not about to get code-reviewed. At most, if anything, it would be:

"explain this class/function": I'd expect you to vaguely know the answer after reading it

or, "why did you do <something> this way?": answers like "I got it from SO", "I don't know of a better way" are perfectly fine.
