MeeeetUp — Event & Coworking Platform

An event and coworking platform for the Japanese market: hosts publish events, sell and approve tickets, and check attendees in at the door, while coworking operators list spaces, manage rooms, and track who is currently in the building.

Overview

Two products ship from one codebase — an events site where anyone can discover an event, apply through a host-configured form, pay, and get approved, and a coworking site where a space owns its rooms and its own recurring events. Hosts get a dashboard for registrations, communication, analytics, and door check-in; operators additionally get room booking and automatic checkout.

Key Achievements

• Two products, one platform — Events and coworking run from a shared feature and design-system layer with build-time path branching instead of forked codebases, so a fix ships to both
• Face check-in at the door — Camera-based reception recognises arriving attendees and checks them in or out, with liveness verification, manual search, and QR fallback so reception never dead-ends
• Host-configurable application forms — Hosts compose their own registration forms (text, number, radio, checkbox, dropdown) instead of requesting a schema change per event
• Per-event email customisation — Hosts override subject and body of participant emails with live preview, while the shared template keeps branding consistent
• Analytics dashboard — Registrations, approvals, check-ins, conversion, and revenue with time-series breakdowns, filters, and CSV export
• Bulk email pipeline — Participant mail is queued and processed by a dedicated worker rather than sent inline, keeping request latency independent of audience size
• Feature-flag discipline — Every user-facing change ships behind a flag resolved from a single source of truth, so incomplete work merges safely
• Design system with visual docs — Shared component library documented in Storybook, covered by unit and end-to-end tests

Key Features

• Event publishing & discovery — Public event pages with search, map, categories, and calendar subscription
• Registration & ticketing — Application forms, approval and sold-out flows, ticket types, and card payments
• Host & participant dashboards — Separate surfaces for organisers and attendees, including co-organiser access
• Coworking spaces & rooms — Spaces own rooms and child events; management pages with server-side search, filter, sort, and pagination
• Automatic checkout — Scheduled job closes forgotten check-ins
• Facial reception — Real-time detection with confidence scoring, auto-confirm on a single match, and a signup path for first-time visitors
• Recurring events — Repeat scheduling for regularly held sessions
• Localisation — Multi-language UI with generated translation types
• Platform admin — Internal console for operating the platform
• Public API reference — Self-documenting API reference for integrators
