I built ticketing for limited-quota premium events, with transactional booking to prevent overselling, payment webhooks, ticket tiers and QR e-tickets.
Highlights
- Prevented overselling through inventory locking
- Integrated payment gateway checkout with webhooks and an audit trail
- Reduced operations overhead by 40% through automated QR e-ticket generation and check-in (self-reported)
