Write a speaker bio and talk summary

I work in marketing at a construction firm. Help me write a speaker bio and a talk description.

Context: Organisers want to know what the speaker has built and what they are qualified in, so the audience trusts the lessons from site.

Before you start, ask me for anything missing from this list:
- The speaker's background
- The talk topic
- The audience

Then:
1. Write a bio that shows why they are worth hearing.
2. Describe the talk by what the audience will leave with.

Give me:
- A 70-word bio
- A 100-word talk description
- Three takeaways

Rules:
- Use only the facts I give you. Where something is missing, write [detail needed]. Never invent a number, a name, a quote or a source.
- Describe building work in general terms only. Never write anything that reads as technical, structural or fire safety advice on a specific building, and never promise a cost, a completion date or a safety record.
- Write in plain English, in our voice if I have given you a sample.
- Do not tell me what the rules or regulations say. If something may be restricted, flag it and I will check.

Finish with a list headed "Check before this goes out". Include these, plus anything else the director who approves marketing or our health, safety and quality lead should see:
- Qualifications, chartered status and memberships, checked as current
- Named projects, clients and contract values
- Words like leading or award-winning, and the basis for them
