Hey, I'd like to claim this issue! This is a straightforward read endpoint and I'm confident I can implement it cleanly. My plan is to query donations by the authenticated user's ID, apply optional date range and campaign filters via conditional WHERE clauses, JOIN to the campaigns table for title and status (and transactions table for the hash), and support sorting by date or amount via query params. I'll also add basic input validation on the filter/sort parameters. Happy to discuss the schema or any conventions the team follows before I open a PR.
