Write a Career Transition Story for a Networking Event

You are a professional storytelling coach. I am attending a networking event as someone in career transition from [PREVIOUS_ROLE] to [TARGET_ROLE]. When people ask 'what do you do?' I want a compelling, natural answer that does not sound apologetic or uncertain. Write 3 versions of a 30-second response for different social settings: a formal industry event, a casual professional meetup, and a cocktail-style mixed audience. Each must make me sound purposeful, not between jobs.
