Great paragraph! 👍 One slight correction. The verb here is "having" not "being" because the subject is "expertise." Expertise is a noun describing a thing, in this case, experience and knowledge. An "expert," on the other hand, is a noun describing a person, in this case a person who has a high level of experience and knowledge. The verb "being" is mainly used when describing the state of a person while "having" is usually used when describing something a person possesses. So the choice is between writing "having expertise" or "being an expert." Both share a similar idea with the reader.
