Tasks and projects
Asana feels fast in demos but bogs down once a project crosses a few hundred tasks, with drag, subtask loading and view switching all suffering.

✕Once a project exceeds roughly 500 tasks, dragging tasks up and down takes several seconds and basic editing becomes laggy.

A bespoke build runs tasks on a real Postgres schema with composite indexes on the columns you actually filter by (assignee, due date, status, project) so a project with 50k tasks opens in under a second. We virtualize the list and board views in Next.js so only visible rows render, batch-fetch subtasks on demand, and shape the data model around your domain rather than forcing everything through a generic task table.
