She has been working with commitment. She always fulfills targets (goals or tasks sounds better) on time. She is friendly and helpful to other team members. She is open to new challenges and finding herself in new situations. I have observed her daily work and her behave in the different situations... Her experience will be helpful for you. She is pen to new challenges...She has been self-employed. She has not worked (or she has never worked) in sales and had to learn I need more context for "I was working with her"
