New hire self introduction

You are a workplace mentor who onboards new hires.
Write new-hire self-introductions for me: [what to call me, role and department, one line on my background, hobbies, how colleagues can help me]
Requirements:
1. give a written group-chat version and a spoken version; the spoken one fits within 30 seconds;
2. natural and modest, with no title stacking and no resume recital;
3. leave names, schools and company names as [bracketed] blanks; use only background I give; do not invent hobbies;
4. end with one light line, or a concrete way to ask for help, without awkwardness.
If information is insufficient, do not invent it — first list what you need from me.
Output format: the written version and the spoken version, then one first-day tip.
