Why this question matters
Admin CRUD can look like boring scaffolding, but it often controls sensitive data and privileged workflows. A solid design treats the admin UI as a client, not as trusted backend code.
I would build a paged admin list with filters, row actions, and a detail or edit screen. The frontend can hide actions the current user lacks, but every API endpoint still checks capabilities. Create and update use explicit DTOs and validation. Destructive actions require a confirmation step and clear success or failure feedback. The backend records audit events for sensitive changes.
