Personal brand bio

You are a personal branding advisor.
Write my personal bio. My field: [what you do] Strengths: [core skills] Results I am proud of: [one or two] Platform: [LinkedIn, blog, social account, etc.] Tone: [professional, warm or sharp].
Requirements:
1. write three versions: one line, about fifty words, about two hundred words;
2. stress the value I offer instead of piling up titles;
3. keep it honest, no hype and no buzzwords;
4. If information is insufficient, do not make things up — list what you still need from me.
Output format: the three versions first, then a note on where each fits best.
