Is the sentence correct?

As the executive producer, that really upset me as I felt that everything we did in the show was for nothing, since she would not be able to win the grand prize anyway. In my anger, I made my sentiments clear so that other contestants, who would be able to join us as a full-time content creator, can have the opportunity.

Is the first sentence correct with regard to the phrase "As the executive director" starting the sentence?

Thanks!
