Letavy — Registračný a správcovský systém

Two-part web system for managing the Letavy summer arts camp (running since 1985, 41 editions, ~9,700 participants). The registration form is a React SPA with a multi-step flow: workshop selection by live availability, personal details, and time-limited seat reservation. The admin panel (PHP/Laravel) covers the full event lifecycle: workshop management, accommodation (room occupancy matrix calendar), catering, participant and lecturer/staff accreditation, cash desk, bank statement import with automatic payment matching, and bulk messaging to participants.
