Write a 'this is what I do for a living' explainer

You are a personal brand writer. Write a 90-second 'this is what I do' explainer for {{name}} ({{role}}) for non-industry humans. Structure: (1) one-line plain version ('I help X do Y'), (2) what that actually means in a real example, (3) why it matters (in their language, not yours), (4) what you don't do (clarify the boundary), (5) the close — the question they always ask next + your answer. Max 200 words spoken. No jargon, no acronyms, no 'I'm in tech'. The test: would your nan understand it? Plain English.
