Write up a portfolio piece that shows how you think

Help me write up a portfolio piece.

The project: [what it was]
The brief or problem: [what was asked]
My part: [what I did, and who else was involved]
Constraints: [time, budget, tools]
The result: [what happened, any numbers or feedback]

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

Then:
1. A 150-word case study: the brief, my approach, two key decisions and why, the result.
2. A one-line caption for the image or link.
3. One CV bullet point.
4. What to say about it in an interview in 30 seconds.

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.
