Help me write a case study for my portfolio. The client (or an anonymised description), the problem and the date: [CLIENT_PROBLEM]. What I did: [MY_ACTIONS]. Results and evidence: [RESULTS]. Whether I have permission to share: [PERMISSION].

Interview me first with five questions to uncover details I have forgotten. Then write a case study of 350 to 450 words with sections: situation, my approach, what changed, result, and what I learned. Use only facts I gave and mark gaps [ADD NUMBER]. Provide a short version of 80 words for a proposal and a pull quote suggestion. Check confidentiality: remind me to confirm what I can publish and to anonymise where needed.

Add a checklist for adding visuals, quotes and a call to action to the case study without exaggerating the results.

Add a section on structure and evidence. Offer two layouts, a long-form story and a one-page scannable summary with headline results, and recommend which suits my audience. Provide a checklist for evidence: before-and-after figures with dates, a screenshot with sensitive details hidden, a quote from the client, and a link only if permitted. Give guidance on honest attribution when a team contributed, on describing results that are partly outside my control, and on avoiding claims such as doubled sales unless I can show the basis. Write a short outline for a 90-second spoken version I can use on calls. Finish with a rule for updating the portfolio every quarter and removing work that no longer represents the services I want to sell.

Finally, add a one-page checklist for permission and accuracy before publication: written approval from the client, figures verified, confidential details removed, and a date for reviewing whether the case study still represents my work.

Tell me to keep a private file with the evidence behind every claim, such as screenshots and emails, in case a prospective client asks for proof.

Interview question 1: What was the situation before you were hired?
Draft (about 110 words, invented): 'A local bakery sent customers to a booking page that took five clicks. I redesigned the page with a single form and clearer photographs. Within eight weeks, online orders rose from about 12 to 20 a week [client-reported]. Lesson: simpler forms win. Used with the client's written permission.'
Gaps to fill: exact dates, how orders were counted [ADD NUMBER].
Pull quote suggestion (client-approved only): 'Orders became easier to place, and we saw the difference within weeks.'
