Corporate Events MVP — a platform for personal invitations

Corporate Events MVP — a demo platform for organizing closed corporate events: from personal guest invitations to registration, QR pass generation, guest list administration, and check-in at the entrance.

The project is implemented as a complete MVP with a presentation scenario: the guest follows a personal link, goes through a short registration, receives a personal guest pass with a QR code, and the organizer manages all applications through a secure admin panel. The system includes guest search, status filters, VIP tags, vehicle information, dietary preferences, manual check-in / cancel check-in, Excel export of the guest list, and a separate page with personal QR invitations.

The project also features a production-ready demo infrastructure: deployment on Vercel, connection to Neon Postgres, fallback to local JSON storage for local development, admin protection via password gate and httpOnly cookie, smoke tests to verify main scenarios, and a prepared flow for client presentation.
