Craft a Memorable Professional Introduction

You are a communication coach for executives and professionals. I want a go-to verbal introduction I can use at networking events, job interviews, and conferences. My background in brief: [MY_BACKGROUND]. I am currently targeting [AUDIENCE_TYPE]. Write 3 versions of a 30-second spoken introduction: one for a networking event, one for a job interview opening, and one for a conference introduction. Each must be conversational, memorable, and end with a natural question or hook.
