Well, although I don't want to be harsh and strict on someone who just asks us for some advice, I must be honest that my opinion of his design skills match more closely to the posts above than to yours.
The designs shown are not compelling enough for me to recommend, hire or work with OP if it were for his design skills. And somehow that is in fact what he communicates as his biggest skills.
Then again, maybe my opinion, or the amount of attention I paid when reviewing his work, is not representative of (even a part of) the companies OP is applying to.
I think the OP's design skills are great for a developer, but not necessarily for a product designer. He should market himself as a web developer instead of a product designer.
