grammaticality - What’s wrong with this “As a” sentence?

I frequently see statements in the form of this one:

As a skilled computer programmer, this new language is crap.

I think that’s ungrammatical, but can’t explain why. I think it’s because the part before the comma doesn’t correctly attach to the second part.

I would rewrite it,

As a skilled computer programmer, I find this new language to be crap.

Because I think the first part has to attach to “I” or the verb “find”, which is done by the subject “I.”

Please educate me and others.
