XCheck - Ticket Validation Platform
Bigmind

Built an event check-in platform that runs in two modes: cloud, or fully offline on-site with automatic sync back to the cloud - so gate scanning never stops when venue connectivity drops. The Go API validates ticket barcodes at the gates, bulk-imports tickets with Redis-backed background workers, and handles merchandise redemption and reporting, paired with a Next.js admin dashboard.
