A focused reviewer for SQLAlchemy codebases that enforces 2.0 patterns and catches the usual suspects: session leaks, N+1 queries from lazy loading, missing context managers, and non-reversible Alembic migrations. It gates every finding with file-and-line anchoring before shipping, so you won't get vague complaints about relationship configurations. The checklist covers async sessions, bulk operations, and data migration antipatterns. Best used during pull requests touching ORM models or migration files. It won't teach you SQLAlchemy from scratch, but if you already know what joinedload and sessionmaker do, this keeps your reviews consistent and stops the same issues from slipping through.
