Creator membership platform: fans subscribe to a creator through the web app. A subscription service manages tiers and recurring billing through a payment gateway. A content service stores posts, and videos are streamed through a video service with signed URLs. A community service provides chat per creator. A payout service calculates creator earnings minus platform fee and pays by bank transfer each month.

How attendees get into an event quickly: QR scan at the gate, validity check that works even if the internet drops, and a live attendance count.
How user posts on a social or creator platform are moderated: automatic checks, human review of doubtful content, and appeals.
Tables for an event platform: organisers, events, venues, ticket types, orders, tickets and check-ins.
The states of a ticket order, from seat hold through payment to use at the event, including refunds when an event is cancelled.
Where a mid-sized creator's monthly income comes from and where it goes, in thousands of rupees, to plan a sustainable creator business.
