Write a LinkedIn post about your work that doesn't feel like bragging

Help me write a LinkedIn post about my work.

What happened: [project, milestone, lesson]
Who helped: [names or teams]
Why it matters: [to customers, the team, me]
What I learned: [one thing]
What I can't share: [e.g. client names, figures]

Ask me up to 3 short questions first if anything important is missing. Wait for my answers.

Then:
1. Two versions under 150 words: one story-led, one lesson-led. Each opens with a short first line that makes people stop scrolling.
2. Credit for others, in a natural way.
3. A note on who I could tag, for me to check with them first.
4. One question at the end to invite comments.

No buzzwords, and no more than two hashtags. Only use what I've told you, leave blanks for anything I haven't given, and don't invent facts, dates or results. UK English.
