MeeeetUp FaceID
Face recognition check-in platform for events, offices, hotels, and venues — people register their face once through an invite link, then cameras at entry points recognize them automatically and mark them as arrived, with no tickets, scanning, or app needed. Currently in active development. Sold as a face-ID provider service other products integrate with. Built as a Turborepo monorepo: a Hono + Bun API with layered repository/domain/service architecture, Drizzle ORM + PostgreSQL, a versioned public API with auto-generated OpenAPI docs, Vite + React + TanStack Router consoles, and a distributable cross-platform face-capture SDK (web MediaPipe + React Native ML Kit) that scores faces on-device and uploads only the best frame per person.Next.jsReactReact NativeViteTypeScriptHonoPostgreSQLDrizzle ORMTanStack QueryshadcnTailwind CSSAWSDocker
