[Lede — one paragraph that sets the stakes. What problem the product actually solves; who the user is. Avoid the "senior capstone" framing — anchor to the users and the outcome.]
[Placeholder — the business/user context. Two paragraphs. Resist the urge to describe features; describe whose day this is trying to improve and what blocks them today.]
[Placeholder — concretely what you owned. In product/PM terms: roadmap, stakeholder calls, tradeoffs you made; in engineering terms: the parts of the system that have your name on them. Include the parts that weren't in your job description.]
[Placeholder — the shipped state. Screenshots, numbers, a dated milestone if one mattered.]
[Placeholder — honest postmortem.]
