を経て

を経て marks a progression or transition that occurs after going through a certain stage, experience, or route. It is often used in formal or written Japanese to describe a sequence: from one stage to another, or to indicate that something was achieved or changed as a result of going through that stage. It can refer to experiences (like jobs, education, or events) as well as physical paths or routes. It emphasizes the process and the resulting situation more than a simple cause-and-effect. It’s common in résumés, reports, and narratives. In daily conversation, you might use more direct phrases like ～を通じて or ～の後で, but を経て carries a slightly more formal nuance.
