1. 有一点点小问题： Actually, what renders me qualified and competen is, in my own view, my rich experience which makes me a perfect candidate for it.2. qualified and competent 是宾语补足语，说明宾语me的情况或状态的。3. 不太对。 这句话的核心句是 What renders me qualified and competent is my rich experience. 因此，is 之后是一个名词词组在做表语；在这个词组之后又加了一个定语从句。4. my rich experience 是单数，如果用复数，就加s. 不加s 永远不可能表示复数。
